Hypothetical situations in Japanese

Level B1

Hypothetical situations in Japanese

Japanese has no separate verb form that directly matches English “would.” A 〜たら condition can describe an imagined situation, while the context and the form of the result show what follows. You’ll also compare polite and casual sentence endings and questions.

Use 〜たら to say “if”

Put the たら condition before the result

仮定する状況を表す部分たら、その場合の行動や結果。

Use context to show an imagined condition

In “もし明日暇だったら、日本語を勉強します。” the condition ends in だったら, and the result uses the polite form 勉強します. Japanese has no special form that directly means “would.” The condition and context show that the situation is imagined. たら can also describe a real condition or something that happens after another event.

In “仕事をする必要がなかったら、一日はどう変わりますか？” the condition again uses たら, and 変わりますか asks politely about the result. English often uses “would” in the result and a past-looking form in the if-clause, but Japanese uses a different pattern.

Ask about the result after the condition

仮定する状況を表す部分たら、疑問語を含む結果の質問？

Choose polite or casual endings

“もっと時間があったら、何をする？” is casual: the question ends with する and has no polite ending. “仕事をする必要がなかったら、一日はどう変わりますか？” is polite, using ます and か. The polite example “もし明日暇だったら、日本語を勉強します。” uses the same style.

Japanese questions do not need the subject and verb to change places as they do in some English questions. 何 or どう appears in the question, and a casual question can be marked by rising intonation; the polite form uses か.
