YukaBoth 〜した時 and 〜した途端 can follow a verb in past form, but they describe very different timing. Let’s break it down!
| Expression | Reading | Meaning |
|---|---|---|
| 〜した時 | shita toki | when ~ happened (general time reference) |
| 〜した途端 | shita totan | the moment ~ happened (immediate result) |
〜した時: When Something Happened
〜した時 is the past-tense equivalent of 〜する時 (when doing). It refers to a point in time — not necessarily the exact instant, but a general “when”:
- 子供だった時 — When I was a child
- 彼に会った時、緊張した。 — When I met him, I was nervous.
- 日本に来た時、何を食べましたか？ — What did you eat when you came to Japan?
〜した途端: The Instant Something Happened
〜した途端（に） means “the moment” or “the instant.” It implies an immediate, often unexpected reaction or result:
- 立った途端に転んだ。 — The moment I stood up, I fell.
- ドアを開けた途端、猫が飛び出した。 — The instant I opened the door, the cat leaped out.
- 薬を飲んだ途端に眠くなった。 — The moment I took the medicine, I felt sleepy.
ReiSo 途端 sounds more dramatic and immediate?
YukaExactly! 途端 = “right at that instant.” It almost always has a surprising or sudden nuance.
