Translation guide
The past perfect tense expresses an action that was completed before another past event. Japanese does not have a direct equivalent tense; instead, it uses the 〜ていた form, temporal conjunctions like 〜たあとで, or relies on context and word order.
Express that something had already happened before another past action or time.
The past progressive/resultative form 〜ていた often corresponds to the past perfect when describing a state or ongoing action that was true before another past event. It emphasizes the continuation or result of the action.
彼が来たとき、私はもう夕食を食べ終えていた。
When he arrived, I had already finished dinner.
その映画はもう見ていたので、別のを選んだ。
I had already seen that movie, so I chose a different one.
Using 〜たあとで (after doing) explicitly sequences events, making the past perfect meaning clear. It is often used when the order of actions is important.
宿題を終えたあとで、ゲームをした。
After I had finished my homework, I played games.
Similar to 〜たあとで, 〜てから emphasizes the sequence of actions. It can imply that the first action was completed before the second began.
手を洗ってから、料理を始めた。
After I had washed my hands, I started cooking.
Japanese often relies on the natural order of clauses to imply that the first action was completed before the second. No special form is needed if the sequence is clear from context.
朝ごはんを食べて、学校に行った。
I ate breakfast and then went to school. (Implies breakfast was finished before going.)
Express that someone had experienced something before a certain past time.
This pattern means 'had the experience of doing something' and is the standard way to express past perfect experiences. It uses the past form of ある (あった) to indicate the experience existed before the reference time.
日本に行ったことがあったので、案内できた。
I had been to Japan before, so I could guide them.
彼女は以前にその本を読んだことがあった。
She had read that book before.
Express that something was supposed to happen but didn't, or that a past expectation was not met.
This pattern means 'was supposed to' or 'should have', indicating an expectation that was not fulfilled. It often corresponds to the past perfect in English when expressing a plan that had been made.
彼は来るはずだったが、来なかった。
He was supposed to come, but he didn't.
This expresses an intention that existed in the past but was not carried out. It translates to 'had intended to' or 'was planning to'.
買い物に行くつもりだったが、雨が降った。
I had intended to go shopping, but it rained.
〜ていた emphasizes the state or ongoing nature of an action before another past event, similar to past perfect. 〜た simply states a past action without necessarily implying completion before another event. Use 〜ていた when the completion or resulting state is important.
彼が来たとき、私はもう食べ終えていた。
When he came, I had already finished eating.
彼が来たとき、私は食べた。
When he came, I ate. (Could mean I ate after he arrived.)
English past perfect often sounds unnatural if directly translated into Japanese. Instead, use temporal words like もう (already) or 前に (before) with simple past forms, or rely on clause order to show sequence.
