いかんにかかわらず / いかんによらず / いかんをとわず means regardless of; whether or not; doesn’t matter whether ~. It is a JLPT N1 Japanese grammar pattern that states a rule, intention, or outcome is unaffected by the circumstances or specifics of a situation.

This grammar point often appears in formal announcements, business documents, policy statements, and JLPT N1 reading passages. If you want to express that something holds true no matter what the situation is, いかんにかかわらず / いかんによらず / いかんをとわず is a pattern that adds precision and a formal, authoritative tone to your Japanese.

Regardless of the outcome, regardless of the reason — this pattern makes your stance ironclad.

What does いかんにかかわらず / いかんによらず / いかんをとわず mean?

Use いかんにかかわらず, いかんによらず, or いかんをとわず when you want to express that something is not dependent on a particular circumstance — that the result, rule, or action remains the same regardless of that factor.

Natural translations include:

  • regardless of
  • whether or not
  • it doesn’t matter whether ~

All three expressions are largely interchangeable. They differ only slightly in register and frequency: いかんにかかわらず is the most common in formal writing, いかんによらず is its direct equivalent, and いかんをとわず often appears in set phrases or when emphasising “we don’t even ask about the circumstances”.

How to form いかんにかかわらず / いかんによらず / いかんをとわず

Noun + の + いかん + にかかわらず / によらず / をとわず

The core is the word いかん (如何(いかん)), meaning “how; what state; circumstances.” It attaches to a preceding noun with の to form a phrase like “the state of N,” after which you add the fixed expression.

Noun の いかん にかかわらず
Noun の いかん によらず
Noun の いかん をとわず

Examples of the pattern:

  • 結果(けっか)のいかんにかかわらず
  • 理由(りゆう)のいかんによらず
  • 年齢(ねんれい)のいかんをとわず

In legal or very terse writing you may occasionally see the の dropped, but keeping it is safer for learners.

When is いかんにかかわらず / いかんによらず / いかんをとわず used?

Use these patterns in situations like:

  • emphasising determination or impartiality

Tone and register:

  • formal — typical of written Japanese, speeches, and official contexts
  • not used in casual conversation unless for ironic or emphatic effect

Nuance of いかんにかかわらず / いかんによらず / いかんをとわず

The key nuance is unwavering uniformity: the speaker declares that the statement holds true under any set of circumstances connected with the noun. It’s not just “even if…,” it’s “and the circumstances don’t even enter the equation.”

This matters because:

  • It signals firmness — a rule, a principle, a promise — not just indifference.
  • いかんをとわず literally means “without asking about the circumstances,” so it often appears in contexts where the entity making the decision chooses not to scrutinise the variable (age, gender, background). That gives it a slightly more “open-door” feel, but the core logic is the same.

いかんにかかわらず / いかんによらず / いかんをとわず vs いかんによっては

Both patterns revolve around いかん (circumstances), but they pull in opposite directions.

いかんにかかわらず
regardless of
Used when the outcome is the same under any circumstances.
結果(けっか)のいかんにかかわらず、報告(ほうこく)してください。
Regardless of the result, please report it.
いかんによっては
depending on
Used when the outcome changes based on the circumstances.
結果(けっか)のいかんによっては、計画(けいかく)を変更(へんこう)します。
Depending on the result, we may change the plan.

If both translations seem possible, ask yourself: “Is the speaker saying the situation does or doesn’t influence what happens next?” That’s your clue.

Common mistakes with いかんにかかわらず / いかんによらず / いかんをとわず

❌ 結果(けっか)いかんにかかわらず、すぐに連絡(れんらく)します。
✅ 結果(けっか)のいかんにかかわらず、すぐに連絡(れんらく)します。
The の before いかん is nearly always required. Omitting it sounds clipped and unnatural.
❌ いかんにかかわらず、雨(あめ)が降っ(ふっ)ている。
✅ 雨(あめ)が降っ(ふっ)ているかいないかに関わら(かかわら)ず、出かけ(でかけ)ます。
The pattern must attach to a noun (with の) that names the variable. It cannot float by itself at the start of a sentence without that anchor.
