Questions & Answers about katsute kono machi ni sunda.
Japanese often leaves out the subject when it is clear from context.
So かつて この 町 に 住んだ。 can mean something like I once lived in this town, he once lived in this town, and so on, depending on the situation.
If you want to state the subject explicitly, you could say:
- 私はかつてこの町に住んだ。
- 彼はかつてこの町に住んだ。
But in natural Japanese, leaving it out is very common.
かつて is an adverb. It means formerly, once, or at one time.
It has a somewhat formal or literary feel compared with very casual everyday alternatives like 昔.
For example:
- 昔、この町に住んでいた。
more conversational - かつて、この町に住んだ。
more formal or narrative
So かつて is not wrong at all, but it can sound a bit more written or reflective.
