は別として (wa betsu toshite): Meaning, Grammar, and Usage

A grammatical breakdown of は別として: its structure, nuances, and use in setting a matter aside or marking an exception.

Category: grammar-breakdowns

What does は別として (wa betsu toshite) mean in Japanese, and how do you use it to set a matter aside or mark an exception?

Depending on the context, は別として (wa betsu to shite) can be translated as “leaving aside…,” “regardless of…”, or, when it introduces an exception, “except for…”.

The construction is used to keep one element separate from what the speaker intends to state in the rest of the sentence.

The speaker can:

  • Set one aspect of the issue aside and focus on something else;
  • Distinguish one case from the rest and exclude it from a general statement.

These two uses share the underlying idea of “considering separately,” but apply that separation in different ways. In the first, the speaker continues without taking a particular aspect into account or without first resolving a preliminary issue; in the second, the scope of the following statement is limited by identifying an exception.

An aspect that is set aside may still be important: the construction simply signals that it is being excluded from consideration for what follows.

The basic structure is Aは別として、B: A indicates the element treated separately, while B contains what the speaker goes on to address. は can be preceded by a noun or noun phrase, but (as we will see) also by an issue expressed through a clause followed by かどうか, “whether… or not.”

The construction can therefore set aside either a specific element or the question of whether a particular situation occurs.

An initial breakdown lets us distinguish は, 別, and として.

  • は is the particle that presents A as the topic of the first part of the sentence and helps distinguish it from what the rest of the sentence focuses on;
  • 別 (べつ, betsu) expresses the idea of something distinct, separate, or to be treated on its own;
  • として, finally, links this first part to the following clause.

To understand how these elements work together to produce the meaning of the construction, however, we need to recognize the form from which として derives.

In 別として, として is the -て form of とする: the particle と remains unchanged, while the verb する takes the form して. The connection with とする, already examined in the article devoted to that construction, is therefore essential.

Here とする has the value “to regard or treat as”: と introduces the qualification 別, while する expresses the idea of treating the element in question in those terms. 別とする can therefore be understood as “to regard as separate,” “to treat as a separate case.” With 別として, this operation is linked to what follows: “regarding … separately,” and thus, more naturally in English, “leaving … aside.”

We can therefore reconstruct an initial overall logic: A is presented by は, treated as separate through 別とする, and linked to what follows by the -て form.

The idea of separation remains recognizable within the expression and applies to the organization of discourse: what is set aside or excluded is distinguished from what the speaker intends to state.

Starting from this initial reading, we will examine the meaning and usage in greater depth, clarify the formation, and analyze the individual components before recombining them and assessing how transparent the overall meaning is. Register, usage contexts, and examples will then show how this mechanism operates in actual sentences.

は別として (wa betsu toshite): Meaning and Usage in Japanese

The core of は別として is treating something separately from what the speaker intends to state. In the structure Aは別として、B, the speaker identifies an element A and separates it from the consideration expressed in B. This separation may concern an aspect that is set aside in the discourse or a case that is excluded from the scope of the following statement. This gives rise to the construction’s two main readings: “leaving A aside” and “except for A.”

In the first use, A represents an aspect of the issue that the speaker chooses not to dwell on, in order to focus on what follows. A criterion of evaluation, a possible objection, a decision yet to be made, or an issue that the speaker prefers to examine separately can all be set aside.

Apart from the price, this computer is easy to use.

The sentence separates the price from the computer’s ease of use. The judgment concerns the latter, while the cost is left out of consideration.

The speaker may consider the computer too expensive while still wanting to acknowledge that it is easy to use; alternatively, they may want to discuss its features before addressing the issue of price. Any reservation about the cost is inferred from context: は別として, by itself, does not state that the price is high or disadvantageous.

This use is particularly helpful when one evaluation needs to be separated from another. An object can be functional regardless of its appearance, an experience can have value regardless of the outcome achieved, and an argument can deserve attention regardless of whether one agrees with it.

The construction makes it possible to specify the aspect being evaluated, preventing one consideration from being automatically extended to all the others.

The element set aside can also be an entire issue expressed through かどうか, “whether… or not.” In this case, the speaker proceeds without treating the answer to that question as a prerequisite for what they intend to say or do.

Leaving aside for the moment the question of whether we agree or not, let’s first listen to the explanation.

Here two operations are kept distinct: listening to the explanation and deciding whether to agree. The proposal to listen remains valid without first having to resolve the question of agreement. は別として does not in itself express approval or disapproval: it allows that evaluation to be kept separate from the proposed action.

Likewise, when the question of whether something is possible, successful, or advisable is set aside, the rest of the sentence may concern a fact, a judgment, a desire, or an invitation to act.

The setting aside applies to the current statement or stage of the discussion. Translating は別として as “leaving … aside for now” can therefore be natural, but this wording does not necessarily imply that the topic will be taken up again later.

The speaker may postpone it, deal with it elsewhere, or simply exclude it from the present consideration. Even an important aspect can be set aside when the aim is to examine another point separately.

The same function can apply to a topic already introduced in the conversation. With それは別として, “that aside” or “leaving that aside,” それ refers back to the preceding content and sets it aside so that the discourse can move on to another point. The separation therefore concerns the way topics are organized, rather than necessarily two characteristics of the same object.

In the second use, A is instead presented as a case to be treated separately from a rule, tendency, or general description. The most appropriate translation is then “except for…,” “excluding…,” or “unless…”.

Except for Sundays, this shop is open every day.

In this sentence, Sunday is separated from the other days: the statement that the shop is open every day applies to the rest of the week. The expression therefore limits the scope of 毎日, “every day,” by indicating which day must be treated separately. In context, it may be implied that the shop is closed on Sundays; the function of the construction is to present that day as an exception to the general description.

The distinction between the two uses depends on the relationship between A and what follows. In the computer example, price is a criterion left out of the judgment about ease of use. In the shop example, Sunday is a case excluded from the generalization about opening hours.

Translating both sentences with “except for…” would make the first unnatural; always translating them with “regardless of…” would instead obscure the exclusion reading of the second.

In the setting-aside use, は別として can be close in meaning to はともかく and はさておき, which are also used to put an issue aside and focus on something else. In the exception use, it is closer to を除いて, which literally means “excluding…”.

As already mentioned, the variant は別にして is also found and can express the same two meanings. These similarities need to be evaluated in context: whether one expression can replace another depends on the type of separation being made.

は別として: formation and grammatical structure

The final sequence は別として remains unchanged, while the form of the element that precedes it varies. A noun phrase, an issue expressed through an interrogative clause, a pair of alternatives, or a situation presented as a particular “case” can all be set aside.

In the patterns below, NP stands for a noun phrase: a noun, possibly accompanied by words that specify or modify it. Sinf instead indicates a clause whose predicate is in the plain form, that is, a form without です or ます. This label refers to the predicate of the clause embedded in the construction: the remainder of the sentence may still end in a polite form.

The plain form includes affirmative and negative forms, both non-past and past. The non-past, in turn, can refer to a present, habitual, or future situation. It is also important to distinguish the form used before か from the one used before 場合: with nouns and な-adjectives, the required form changes according to what follows.

NPは別として: a noun phrase

In this construction, は別として attaches directly to the noun phrase, with no copula inserted between the noun and は. The noun may refer to a person, a group, an object, an aspect of the issue, or a topic.

The noun phrase may consist of a single word, such as 費用, “cost,” or a more elaborate phrase, such as 費用の問題, “the issue of cost.” Words that modify the noun are part of the element being set aside.

Leaving aside the issue of cost, I am in favor of that plan.

Here 費用の問題 is the noun phrase to which は別として is added. The construction sets aside the issue of cost, while the following clause expresses a judgment about the plan.

This pattern must be distinguished from the interrogative pattern: 学生は別として sets students aside as a group; 学生かどうかは別として, by contrast, sets aside the question of whether someone is a student.

Sinfか(どうか)は別として: an issue to set aside

In this pattern, the clause preceding は別として is presented as a question: “whether a particular situation is true or not.” かどうか makes this alternative explicit, while か alone may be sufficient when the alternative is clear from context.

Both 来るかどうかは別として and 来るかは別として are therefore possible, with the meaning “leaving aside the question of whether they will come or not.”

The form used depends on the type of predicate.

With a noun, the だ of the non-past affirmative is dropped before か. Thus, 学生だ, “is a student,” becomes 学生かどうか, “whether someone is a student or not,” and then 学生かどうかは別として.

Regardless of whether he is a student or not, anyone can take part in this course.

The content being set aside is the entire question 彼が学生かどうか. The subject 彼が remains inside the interrogative clause; は instead attaches to the question as a whole.

With a な-adjective, the non-past affirmative だ is likewise dropped. From 便利だ, “is convenient,” we get 便利かどうか, with no な added before か.

Leaving aside the question of whether this method is convenient or not, we need to check its safety.

The form is therefore 便利かどうかは別として. な is used when the adjective modifies a noun and will be discussed again in the construction with 場合.

With an い-adjective, the non-past affirmative keeps its ordinary form: 高い → 高いかどうか. No copula is added between the adjective and か.

Leaving aside the question of whether the price is high or not, let’s check the quality first.

With a verb, the plain form required by the content of the clause is used. In the non-past affirmative, this is the dictionary form, such as 来る, “to come,” followed by か or かどうか.

Regardless of whether he comes or not, we will start the meeting as scheduled.

This example uses か on its own: the come-or-not alternative is still clear from context. The alternative could be made explicit with 彼が来るかどうかは別として.

The omission of だ applies specifically to the non-past affirmative of nouns and な-adjectives. Past and negative forms, by contrast, retain their own inflection: 学生だったかどうか, 便利だったかどうか, 学生ではないかどうか, 便利ではないかどうか. Verbs and い-adjectives can likewise appear in past or negative forms, as in 来たかどうか, 来ないかどうか, 高かったかどうか, and 高くないかどうか.

If the clause contains an interrogative word, か can mark a question other than a “yes-or-no” question. For example, 誰が来るかは別として means “leaving aside the question of who will come.” In this use, どうか is not added because the question concerns the identity of the person rather than the truth of a particular proposition.

XかYかは別として: two alternatives stated separately

In this pattern, two explicit alternatives, X and Y, are presented, and the question of which one applies or occurs is set aside. The alternatives may be two distinct possibilities or two terms with opposite meanings.

In the pattern examined here, nouns and な-adjectives appear without the non-past affirmative だ, while い-adjectives and verbs retain their ordinary non-past form.

With two nouns, a sequence such as 教師か学生か, “teacher or student,” is formed. Each noun represents one of the alternatives.

Regardless of whether someone is a teacher or a student, anyone can speak freely in this study group.

The distinction between the two roles is irrelevant to the opportunity to speak freely.

With two な-adjectives, forms without だ are used, as in 便利か不便か, “convenient or inconvenient.”

Leaving aside the question of whether it is convenient or inconvenient, this feature is necessary.

便利 and 不便 express two contrasting evaluations. The question of which evaluation is appropriate is kept separate from the statement about the necessity of the feature.

With two い-adjectives, both retain the non-past form: いいか悪いか, “good or bad.”

Leaving aside the question of whether it is good or bad, many people use this method.

With pairs of this kind, such as いい(か)悪い(か), か can be omitted. The form without the particles can therefore be:

Leaving aside the question of whether it is good or bad, many people use this method.

Grammatically, this possibility can be understood by observing that いい悪い can function as a nominal expression representing the entire alternative “good or bad”. The two terms are placed side by side and form a recognizable topic, comparable to the question of whether something is good or not.

With か, the alternative is expressed through an explicit interrogative structure; without か, it is represented by the pair itself. This reading explains how the form works without appealing to any supposed difficulty of pronunciation.

The omission therefore depends on whether the pair can be recognized as a coherent expression in context. It should not be turned into a general rule that か can be omitted after any い-adjective: arbitrarily placing two adjectives side by side does not necessarily produce a natural construction.

With two verbs, ordinary non-past forms are used, as in 買うか借りるか, “buy or borrow.”

Regardless of whether I buy or borrow one, I need a car for work.

The issue being set aside concerns the choice between two different actions. The following clause, by contrast, states the need for a car, regardless of which option is chosen.

X affirmativeかX negativeかは別として: a possibility and its negation

This construction presents the same predicate first in the affirmative and then in the negative. This makes explicit the question of whether a particular situation occurs or not.

The difference from the previous pattern lies in how the alternatives are formed. 便利か不便か contrasts two different adjectives; 便利か便利ではないか repeats the same adjective in its negative form. Likewise, 悪い is an adjective with a meaning opposite to いい, while the grammatical negative of いい is よくない.

With a noun, the non-past affirmative appears without だ before か; the negative is formed with ではない or でない. This yields a sequence such as 会員か会員ではないか, “a member or not a member.”

Regardless of whether someone is a member or not, anyone can participate in this event.

With a な-adjective, the affirmative appears without だ and the negative retains ではない or でない: 好きか好きではないか, “whether one likes it or not.”

Leaving aside the question of whether I like that job or not, I intend to see it through to the end.

With an い-adjective, the negative is formed by replacing the ending い with くない. From 高い we get 高くない, and therefore 高いか高くないか, “high or not high.”

Regardless of whether the price is high or not, I want to check the quality.

With a verb, the affirmative and negative plain forms are placed side by side: 参加するか参加しないか, “participate or not participate.”

Regardless of whether you participate or not, please give me an answer by tomorrow.

Verb pairs without か are also found, such as するしないは別として or できるできないは別として. Here too, the two forms can jointly represent a recognizable issue: doing or not doing, being able or unable to do something. The existence of such sequences shows that this juxtaposition reflects the way alternatives are represented, rather than being a phonetic property exclusive to い-adjectives.

The preceding examples use the non-past. To refer to a past situation, both alternatives can be put in the past, as in 参加したか参加しなかったかは別として, “leaving aside the question of whether they participated or not.”

Sinf場合は別として: a case or situation to be treated separately

In this construction, the preceding clause specifies which case is being set aside or excluded. 場合 (ばあい, baai) is a noun meaning “case” or “situation”: the predicate that precedes it must therefore take the form required to modify a noun.

The description together with 場合 forms the element to which は別として attaches. The usual reading is “except when…,” “with the exception of cases in which…,” or “leaving aside situations in which….”

For this reason, the Sinf場合 pattern requires a clarification: with nouns and な-adjectives, the non-past affirmative does not retain だ. Nouns connect through の; な-adjectives through な. In the past, both instead use だった.

With a noun: Nの場合 and Nだった場合

In the non-past affirmative, 学生だ, “is a student,” becomes 学生の場合, “if the person is a student.” If the content refers to a past situation, 学生だった場合 is used, “if the person was a student.”

Non-past

Except in cases where the participant is a student, the participation fee is 3,000 yen.

Past

Except in cases where the participant was a student, last year we collected a participation fee of 3,000 yen from everyone.

In the first example, student status is treated as an exception to the current rule; in the second, 学生だった describes the participants’ status in the previous year.

With a な-adjective: な場合 and だった場合

In the non-past affirmative, 複雑だ, “is complex,” becomes 複雑な場合. In the past, 複雑だった場合 is used instead. The な serves to connect the adjective to the noun 場合 and is not added after だった.

Non-past

Except in cases where the explanation is complex, one interpreter is enough.

Past

Except in cases where the explanation was complex, one interpreter was enough during last year’s training.

The difference between 複雑な場合 and 複雑だった場合 concerns the form of the predicate describing the case: in the second example, the complexity refers to explanations given during training that has already taken place.

With an い-adjective: い場合 and かった場合

An い-adjective attaches directly to 場合: 低い場合, “when it is low.” In the past, the ending becomes かった: 低かった場合, “when it was low.” No の or な is inserted between the adjective and 場合.

Non-past

Unless the temperature is low, open the windows to ventilate the room.

Past

Except when the temperature was low, last month I opened the windows every morning to air the room.

In the second example, 低かった describes the temperature in the situations that occurred during the previous month; 場合 identifies those situations as the cases excluded from the habit described in the following clause.

With a verb: ordinary non-past form and -た form

The verb attaches directly to 場合. In the non-past affirmative, the dictionary form is used, as in 付き添う, “to accompany”; in the past, 付き添った is used.

Non-past

Unless a staff member accompanies visitors, entry to this area is not permitted.

Past

Except in cases where a staff member accompanied visitors, last year we did not allow access to this area.

The form 付き添う場合 identifies the case covered by the rule; 付き添った場合, in the second example, refers to cases that occurred in the previous year.

With verbs, however, the plain past -た form must be distinguished from reference to absolute past time: this form can also present an event as completed within a hypothetical situation, even a future one. The actual temporal reference therefore depends on context. In examples referring to past events, expressions such as 昨年, “last year,” and 先月, “last month,” make the time frame explicit.

The construction also allows negative predicates, which attach directly to 場合: 学生ではない場合, 複雑ではない場合, 高くない場合, 参加しない場合. The の and な connections therefore apply to the non-past affirmative of nouns and な-adjectives; they should not be added after a predicate that is already negative or past.

Grammatical breakdown

To understand how は別として expresses the idea of setting something aside, we can examine its three components separately: は, 別, and として.

Each contributes to the construction in a different way: は identifies the issue under consideration, 別 introduces the notion of separation, and として allows that characterization to frame what follows in the sentence. In analyzing this last element, the relationship with とする, the base form that clarifies how it works, will be especially important.

は: presenting the issue as the topic

The particle は, pronounced wa, presents the preceding element as the topic. A first approximation of its value is therefore “as for…,” “with regard to….” In は別として, it identifies precisely what is to be treated separately: a person, a circumstance, an aspect of the problem, or an entire issue.

Its role concerns the organization of information. In 費用は別として, for example, 費用, “costs,” is singled out as the element with respect to which the speaker establishes how the discourse will proceed. The particle makes the scope of 別として clear.

This topic can also consist of an embedded question:

Let’s leave aside for the moment the question of whether he can participate and first decide on the date.

Here は refers to the entire segment 彼が参加できるかどうか, “whether he can participate or not.” The issue being set aside therefore includes both possibilities: that he can participate and that he cannot. The topic introduced by は is the question as a whole.

In this construction, the particle’s contrastive value may also come into play. The element placed before は is distinguished from the other aspects or cases referred to by the rest of the sentence: as for this point, we treat it separately; with respect to the rest, we can proceed. The contrast may be more or less evident depending on context and does not necessarily require both sides to be explicitly named.

The specific contribution of は therefore remains the presentation of the topic, potentially accompanied by contrast. The idea of setting it aside takes shape through the following 別として.

別: marking something as “separate” or “distinct”

別, read betsu, expresses the notion of distinction or separation: something is different from something else, constitutes a separate element, or is considered separately. Japanese dictionaries list it as a noun with adjectival uses; this behavior can be seen, for example, in 別の問題, “a different issue,” and 問題は別だ, “that is a separate issue.”

In は別として, 別 provides the characterization applied to the preceding element: that point is treated as a separate issue with respect to what is being discussed.

The separation often concerns reasoning. In 費用は別として, costs are kept out of the evaluation that follows. In 緊急の場合は別として, “except in emergencies,” a circumstance is instead distinguished from the ordinary cases to which the following statement will apply.

This shared notion makes it possible to understand both the setting aside of an aspect and the exclusion of a case. Context determines which reading predominates.

別 therefore supplies the lexical notion of separation. The idea of treating something in this way emerges through the combination with として.

For a closer look at the origin of 別 and the relationship between its meanings and the grammatical constructions in which it appears, the site has a dedicated article on the kanji 別 (betsu): meaning, origin, readings, and grammatical functions.

として: treating something as distinct and linking it to what follows

In は別として, として helps present what precedes as something to be treated separately and is generally translated as “as….”

For example:

Nozaki-san, as a teacher…

Its value is therefore understood together with 別: 別 expresses the distinction; として allows that distinction to frame what follows. A first interpretive key to 別として is therefore “treating it as a separate issue.”

として derives from とする (“to regard something as…,” or “assuming that…”) and its connection with this form is first and foremost grammatical: として consists of the particle と and して, the て-form of する.

For a closer look at the structure and hypothetical use of とする, the site has an article devoted specifically to this form: とする (to suru): meaning and usage for forming hypotheses.

Thus, として is the connective -て form of とする, allowing it to link to the rest of the sentence. Here, however, translating する simply as “do” would not be very helpful: the operation concerns the way an issue is construed in the discourse.

As noted above, とする can in fact express the meaning “regard as,” “judge as,” or “treat as.” This is the relevant point of reference for understanding 別として: what precedes は is treated as 別, that is, as distinct from the rest (“separate,” “different”). と marks 別 as the characterization applied to the issue, while する contributes the sense of treating it that way.

として therefore does not, by itself, mean “set aside” or “except”. These readings arise from its combination with 別 and from the functioning of the construction は別として as a whole. Nor should the hypothetical meaning of とする be transferred here automatically: treating an issue separately is not the same as assuming that some content is true.

Consider:

“Apart from the price, this computer is easy to use.”

The price is treated separately (literally, “as something separate…”) from the assessment of ease of use. として links this framing to what follows: the speaker continues the evaluation while leaving price out of the criterion under consideration. There is no need to understand this as two successive actions, first a separation and then a judgment; the first part directly establishes how the following statement is to be interpreted.

As for how this use departs from the basic value of とする, the connection with the idea of “regarding or treating as” remains recognizable, but は別として now functions as a conventional construction for organizing discourse. It does not necessarily describe an explicit act of classification: it can directly serve to suspend an issue or exclude a case from the generalization that follows.

The Daijisen, moreover, also records a use of として that allows the preceding issue to be left temporarily in abeyance while the discourse moves on to another topic. This confirms that として can perform a linking and discourse-management function in addition to its better-known value of “in the capacity of.” It is not, however, sufficient to demonstrate a specific historical development of は別として.

In the structure examined here, the contribution of として can therefore be summarized as follows: linking the separate treatment expressed by 別 to the discourse that follows, making that separation the framework within which the subsequent statement is interpreted.

Compositionality vs. idiomaticity: how transparent is は別として?

は別として can be described as a conventional construction with a largely transparent semantic core. Breaking it down makes it possible to recognize the relationship between its parts and its overall meaning: presenting an issue, considering it separately, and continuing the discourse on the basis of that separation.

By transparency we mean precisely the possibility of understanding how the components contribute to the meaning of the expression. The conventional component, by contrast, concerns the way the language regularly uses that combination to perform a particular function.

These two aspects can coexist: an expression can have a recognizable use as a whole while preserving an understandable internal logic.

In the case of は別として, this logic remains visible. は identifies the topic, 別 introduces the characterization of the topic as “separate,” and として, through its relationship with とする, makes it possible to treat that topic according to this qualification while linking it to what follows. The shift from “consider separately” to “leave out of consideration” or “make an exception” is therefore motivated by the functioning of the individual parts.

The transparency becomes apparent, however, only when the relevant grammatical values are recognized. Knowing する only as “do” or として only as “as / in the capacity of” makes the construction difficult to interpret. What is needed is the value of とする as “regard,” “treat as,” or “assign a particular status to.”

A difficulty caused by incomplete knowledge of the components is therefore not enough to show that the meaning of the expression is opaque.

At the same time, analysis of the parts must be accompanied by knowledge of usage. は別として functions as a conventional way of organizing what is taken into consideration in discourse. The speaker can use it to suspend an evaluation, distinguish two issues, or delimit the cases to which a statement applies.

The Daijisen, moreover, records among the uses of として the possibility of temporarily leaving the preceding content in abeyance and moving on to another topic.

Consider:

Result aside, I would like to acknowledge the effort that was made.

The result is treated separately from the evaluation of the effort. The notion of separation helps us understand the sentence, while familiarity with the construction makes the discourse operation immediately recognizable: the speaker chooses which aspect to evaluate while leaving another out of consideration.

The same expression can also have an exclusion reading:

Experts aside, few people can understand this explanation immediately.

Here experts are treated separately, and the statement concerns everyone else. The meaning “except for” remains connected to the notion of separation expressed by 別: one group is distinguished from the domain to which what follows applies.

The parts make the general operation understandable; context specifies how it is applied. In the first example, one aspect of the evaluation is set aside; in the second, a group of cases is excluded. To determine the intended reading, both the preceding element and the following clause must be considered together. This dependence on context is compatible with the transparency of the structure.

The variety of elements that can precede it also shows that は別として constitutes a reusable pattern. The topic can be a noun, a noun phrase, or an issue formulated with かどうか. The operation of treating that content separately remains recognizable, even though what it applies to changes.

The variant は別にして, which performs a similar function in many contexts, likewise preserves the notion of separate consideration. The meaning therefore rests on recognizable grammatical relationships and on lexical content that remains active.

From this perspective, the grammaticalization of として can also coexist with semantic transparency. A form can acquire a stable grammatical function while retaining an understandable connection with the construction from which it derives. In は別として, the link back to 別とする continues to explain why the expression can set aside an issue or mark out an exception.

For learners, analysis and observation of usage therefore perform complementary roles: analysis of the parts clarifies what motivates the meaning; examples show how that underlying logic works in actual usage. The transparency of は別として makes its logic understandable, while familiarity with the construction allows its value to be recognized quickly in context.

Register and contexts of use

は別として is a general-purpose expression that can be used in both spoken and written Japanese. It appears across a range of situations: a conversation between friends, a work discussion, an in-depth article, or a text explaining a procedure. The level of formality depends on the sentence as a whole, the vocabulary chosen, and the relationship between the speakers.

Its function of distinguishing what is temporarily set aside from what the speaker wants to discuss can give the utterance a deliberate, analytical tone: the speaker makes explicit the criterion by which the discourse is being organized. This operation can also concern everyday matters, however, without requiring a particularly formal or serious context.

In informal conversation, for example, は別として can express a desire while leaving in abeyance an evaluation that might otherwise affect it:

Whether it suits me or not, I’d like to try wearing this hat.

The speaker separates the desire to try on the hat from the question of whether it suits them. The ending かぶってみたいな, with な accompanying the expression of desire, contributes to the colloquial tone of the sentence. は別として fits naturally into this way of speaking: it allows the speaker to clarify their point of view even within a spontaneous exchange.

In work discussions, the same construction can serve to delimit the issue to be addressed at a particular stage. When a proposal requires several evaluations, it makes it possible to focus on one aspect before moving on to the overall decision:

Leaving aside for the moment the decision of whether to adopt this proposal, let’s first examine its advantages.

Here は別として helps organize the discussion. The final decision is left open while the proposal’s advantages are examined; まず, “first,” makes the order of the steps explicit. This use is well suited to meetings, discussions between colleagues, and presentations in which the analysis of a possibility needs to be distinguished from its actual approval.

At this point, it is useful to distinguish register from politeness. は別として does not itself express respect or deference toward the interlocutor. In the previous example, the polite tone of the proposal depends primarily on 確認しましょう, “let’s examine.” Replacing it with 確認しよう would make the same sentence suitable in a more familiar interaction.

Even in a polite sentence, the clause preceding かどうか normally retains the plain form required by the construction: 採用するかどうか, “whether to adopt it or not.” The use of する rather than します at this point is therefore fully compatible with a polite sentence ending. The different parts of the sentence perform different grammatical functions.

In writing, は別として is well suited to explanations and arguments in which the author wants to delimit an evaluation, separate two problems, or specify exceptions to a general statement. In a text describing a procedure, for example, one might read:

Except in emergencies, the application must be submitted in advance.

The procedural content and the formulation 行う必要がある, “must be done,” contribute here to an expository style. は別として makes it possible to indicate immediately the limits within which the provision applies. The same delimiting function can also be useful in essays, commentaries, and reports when it is necessary to clarify which cases fall within the scope of the reasoning.

The effect on the interlocutor also depends on what is being set aside. We can imagine, for example, someone asking for clarification about the price of a product and receiving a reply introduced by 値段は別として, “leaving the price aside.” In that situation, the reply might come across as dismissive: the point that matters to the person asking the question is set aside before being addressed.

This possible impression arises from the relationship between the question and the answer, as well as from the tone adopted. If the speakers have already agreed to examine other aspects first, the same expression may be entirely appropriate. When, by contrast, an issue the other person considers important is set aside, acknowledging its importance and explaining why it is being postponed helps make the communicative intent clear.

Usage examples

The following examples illustrate how は別として can set aside a criterion of evaluation, suspend an issue, or exclude a case from the statement that follows.

“Price aside, this chair is comfortable.”

The price is set aside while the comfort of the chair is evaluated. は別として separates two criteria of judgment here: the cost and how the chair feels to sit in.

“Apart from Tanaka, all the other members are doing this work for the first time.”

Tanaka is excluded from the general statement, which applies only to the other members. Here は別として means “except for” or “excluding.”

“Whether or not I can win a prize, I’d like to try entering this work in the contest.”

受賞できるかどうか presents the issue being suspended: the possibility of winning a prize. The desire to enter the contest is expressed independently of the outcome.

“Whether it is convenient to use or not, this app has an attractive design.”

The app’s practicality is separated from its appearance. 便利, a な-adjective, directly precedes かどうか, without だ.

“Whether it is authentic or not, this painting has a distinctive charm.”

本物, “the real thing” or “something authentic,” is a noun preceding かどうか. The speaker sets aside the question of authenticity in order to express an evaluation of the painting’s appeal.

“Whether he is a professional or an amateur, his performance is excellent.”

The nouns プロ and アマチュア present two alternatives through か…か. The evaluation of the performance is kept separate from the performer’s professional status.

“Whether it was good or bad, his remark attracted a great deal of attention.”

The pair of い-adjectives いい・悪い appears without か, in the form いい悪い. The judgment about the remark is set aside in order to highlight the attention it attracted.

“Whether or not I take part, please at least tell me what day the event will be held.”

参加するか参加しないか spells out the two possibilities by using the affirmative and negative forms of the same verb. The request to know the date remains valid in either case.

“Except when the weather is bad, I usually go out on my bike on weekends.”

天気が悪い modifies 場合, identifying the situation excluded from the general tendency. The adjective 悪い is in the non-past form and describes a condition that may recur.

“Unless you have already submitted it, please hand in the report by Friday.”

The case in which the report has already been submitted is excluded from the request. 提出した, in the past form, modifies 場合 and, together with すでに, “already,” presents the submission as a completed action.

Conclusion

Understanding は別として also means learning to recognize the limits of a statement. In the uses examined here, the speaker selects which aspects to consider in their reasoning and which to treat separately. Understanding the message therefore requires attention both to what is stated and to what is left out.

From this function we can draw a useful observation: a favorable judgment about a single aspect does not necessarily amount to overall approval.

Saying that a chair is comfortable while setting its price aside allows us to appreciate its comfort; when deciding whether to buy it, the cost may once again become decisive. An issue that has been set aside can therefore regain relevance when the question being addressed changes.

When reading, especially when faced with a long sentence, a practical method is to identify first the judgment, description, or request expressed in the main part.

Then work back to what precedes は別として, treating it as a single block. In 受賞できるかどうかは別として, for example, the entire question of whether it is possible to win a prize is set aside: recognizing this boundary helps us see that the predicate belongs to the embedded question as a whole.

To check the interpretation, it is useful to formulate a brief paraphrase of the relationship between the parts: “I am evaluating this aspect without considering the other one,” or “this statement applies to the remaining cases.” This step also helps with translation. The choice between “apart from,” “regardless of,” “except for,” and other solutions should make the relationship expressed in the Japanese sentence clear.

To practice using the construction actively, start with a simple statement and add either a criterion to set aside or a case to exclude.

It is also useful to write a short context: describing what the speakers were discussing and which point they now want to address helps confirm that は別として serves a clear communicative purpose. In this way, the grammatical construction is tied to a specific purpose.

The same relationship is worth noting during review: beside each example, note what is being set aside and which statement remains valid within the resulting scope. The same note can accompany different forms, from noun phrases to questions with かどうか and constructions with 場合. In this way, the syntactic patterns studied remain connected to their function.

The relationship between として and とする provides a basis for understanding the operation of “treating as separate.” Working with complete sentences then makes it possible to recognize what is being separated, in relation to which evaluation or generalization, and for what purpose. It is this ability to follow the speaker’s choices that makes the breakdown useful both for understanding texts and for using the construction accurately.
