Translation guide
The subjunctive mood expresses hypothetical, wished-for, or contrary-to-fact situations. Japanese does not have a direct grammatical equivalent; instead, it uses conditional forms, sentence-final particles, and specific constructions to convey similar meanings.
Expressing 'if' or 'suppose' scenarios, often about unreal or imagined situations.
Attach to the past plain form of verbs/adjectives. Used for both real and hypothetical conditions, but context often makes it subjunctive-like.
If I had money, I would go on a trip.
Attach to the conditional stem (e.g., 行けば). Often used for general conditions, but can express hypotheticals.
If I had woken up earlier, I wouldn't have been late.
Attach to plain form. Often implies 'if it is the case that...' and can be used for hypotheticals based on assumptions.
If he is coming, I'll go too.
Expressing 'I wish...' or 'If only...' about unreal situations.
Used to express a wish that something were different. Often carries a sense of regret or longing.
I wish I could speak Japanese better.
Similar to 〜ばいいのに, but using the たら conditional. Slightly more colloquial.
I wish it would be sunny tomorrow.
Used with verbs like 願う (to wish) or 祈る (to pray) to express a hope or wish.
I hope I pass the exam.
Expressing 'should have' or 'would have' about past events that didn't happen.
Expresses regret about not doing something. Literally 'it would have been good if...'
I should have studied more.
Expresses that something should have been done (moral obligation or advisability).
I should have been honest at that time.
Expresses that something was supposed to happen but didn't.
He was supposed to come, but he didn't.
Giving advice or making suggestions using subjunctive-like constructions ('You should...', 'It would be better if...').
Japanese does not have a distinct subjunctive verb form like some European languages. Instead, it relies on conditionals (〜たら, 〜ば, 〜なら) combined with particles like のに or けど to convey hypothetical or contrary-to-fact meanings. Avoid trying to translate the subjunctive literally; focus on the intended nuance.
While all can express conditions, 〜たら is the most versatile and common in spoken Japanese. 〜ば is often used for general truths or logical conditions. 〜なら is used when the condition is based on the speaker's assumption or information. For subjunctive-like meanings, 〜たら and 〜ば are most common, often with のに.
If I had money, I would buy it.
If I had money, I would buy it.
If I were you, I would accept the offer.
I wish it would stop raining.
It is important that he be on time.
Japanese often uses plain fact statements instead of subjunctive; 'ことが重要' expresses necessity without a special mood.
