Where it comes from
Tonkatsu is yōshoku — Western food, as Japan cooked it after opening up in the Meiji era. It began as a version of the European cutlet, pan-fried in butter; Tokyo restaurants made it thicker and deep-fried, and served it already sliced so it could be eaten with chopsticks.
Katsu sounds like the word for winning, so students eat it — often as katsudon — the night before an exam.
