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.
When he arrived, I had already finished dinner.
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.
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.
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.
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.
I had been to Japan before, so I could guide them.
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.
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'.
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.
When he came, I had already finished eating.
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.
