となると / となれば means when it comes to; in such a case; if that happens. It is a JLPT N1 Japanese grammar pattern used to express that once a certain condition is met or a threshold is reached, a particular, often logical, consequence or reaction follows.

This grammar point often appears in news articles, formal discussions, editorials, and JLPT N1 reading passages. If you want to link a hypothetical situation to its natural outcome or response, となると / となれば is a precise tool that sharpens your advanced Japanese.

What does となると / となれば mean?

Use となると / となれば when you want to say “if it comes to that” or “when it comes to X”. It signals that the speaker is presenting a condition (often a new piece of information or a hypothetical scenario) and then drawing a conclusion or describing a natural reaction.

Natural translations include:

  • when it comes to; in such a case; if that happens; once that’s the case

The two forms are largely interchangeable; となれば can feel slightly more literary or emphatic, while となると is extremely common in everyday formal contexts.

How to form となると / となれば

Verb / い-adj
casual form
+ となると
となれば
Noun + となると
となれば
な-adj stem な-adj + だと + なると
なれば

Examples of the pattern:

  • (あめ)降る(ふる)となると中止(ちゅうし)だ。
  • 東京(とうきょう)となると家賃(やちん)高く(たかく)なる。
  • 静か(しずか)となると図書館(としょかん)みたいだ。

The form before the grammar point matters. In JLPT questions, the wrong answer choices often use a similar meaning but attach it to the wrong type of word — for example, a て-form before となると.

When is となると / となれば used?

Use となると / となれば in situations like:

  • presenting a hypothetical condition and its natural consequence
  • reacting to a newly mentioned fact or assumption
  • showing that once a certain threshold is crossed, something else inevitably holds true

Tone and register:

  • slightly formal, often used in written Japanese, news commentary, and business discussions
  • Common in JLPT N1 reading comprehension and grammar sections

となると / となれば example sentences

(かれ)反対するとなると計画しくなる。
If he's against it, the plan becomes difficult.
hypothetical consequence
こんなにくまでいている(みせ)がないとなるとめるしかない。
If there's no shop open this late, we have no choice but to give up.
threshold
となれば(はなし)だ。
When money is involved, it's a different story.
emphatic
大企業就職するとなると競争率い。
When it comes to getting a job at a major company, the competition is fierce.
general condition
首相辞任するとなれば政局混乱するだろう。
If the prime minister steps down, the political situation will likely become chaotic.
hypothetical outcome
一人旅となると準備だ。
When it comes to traveling alone, the preparation is easy.
noun + となると

After reading each sentence, ask what job となると / となれば is doing: it highlights a condition and then tells you what logically or naturally follows. That makes the nuance easier to remember than a one-word translation.

Nuance of となると / となれば

The key nuance is a threshold is crossed, and a reaction or consequence naturally unfolds.

This matters because learners often think of となると as a simple “if”, but it carries a stronger sense of inevitability or “now that we’re talking about this case”. It often implies that until this point, the situation was neutral, but once the topic shifts to X, then Y becomes the unavoidable truth.

For example, if someone says 「海外(かいがい)住む(すむ)となると、ビザが必要(ひつよう)だ」, the nuance is “Once it’s a matter of living abroad (as opposed to just visiting), a visa becomes necessary.” It’s not just a random conditional; it’s the logical switch that flips when the condition is activated.

となると / となれば vs となったら

Both となると / となれば and となったら can express a conditional consequence, but they differ in register and emphasis.

となると / となれば vs となったら
more formal; written, analytical; emphasizes the condition as a threshold more colloquial; conversational; closer to "if it becomes the case that…"
used in news, logical arguments, formal speeches used in everyday talk, less formal contexts

Quick contrast:

  • 一人暮らし(ひとりぐらし)となると貯金(ちょきん)減る(へる)。(formal observation)
  • 一人暮らし(ひとりぐらし)となったら寂しく(さびしく)なるかな。(casual worry)

If both translations seem possible, check the tone. となると / となれば fits situations where you are stating a general truth or a logical result; となったら leans toward personal speculation or a softer “if it turns out that way”.

Common mistakes with となると / となれば

新しい(あたらしい)仕事(しごと)探し(さがし)ているとなると、時間(じかん)がかかる。
新しい(あたらしい)仕事(しごと)探す(さがす)となると、時間(じかん)がかかる。
Use a noun or a plain-form verb before となると, not a て-form.
(かれ)()ないとなると、会議(かいぎ)始めよう(はじめよう)
(かれ)()ないとなると、会議(かいぎ)始める(はじめる)しかない
The main clause after となると typically describes a natural consequence or an inevitable reaction, not a volitional decision (~よう/~つもり) that sounds like a plan.
静か(しずか)となって図書館(としょかん)みたいだ。
静か(しずか)となると図書館(としょかん)みたいだ。
Don't confuse となると with となって (the て-form of なる). となると is a fixed conditional expression.

  • Frequently appears in N1 reading comprehension and grammar sections.

Learning path for となると / となれば

To learn となると / となれば efficiently, start with its formation, then compare it with similar patterns, and finally practice in context.

1
First, make sure you can attach となると and となれば to nouns, verbs, and い-adjectives without hesitation. Practice the な-adj + だとなると pattern until it feels automatic.
2
Next, compare it with となったら. Write two versions of the same scenario — one formal report, one casual chat — and notice how the tone shifts.
3
Then, collect examples from news articles or business emails where となると/となれば appears. Underline the condition and the consequence; check if the sentence still works if you swap to もし~たら — usually the nuance will change.
4
Finally, write paragraphs where you introduce a hypothetical policy or social change and use となると/となれば to explain the expected results. This mirrors N1 essay questions.
  • (あい)まって — because it also deals with conditions combining to produce a result
  • とあれば — because it similarly sets up a conditional premise (“if it’s the case that…”)
  • とあって — because it too marks a reason/condition leading to a natural outcome
  • とばかりに — because it shares the conditional と particle and a sense of “as if to say / just because”
