When I flew HND to SIN in 2019, the flight departed just after midnight and the crew just offered a drink service with amuse bouche and then dimmed the lights until a full breakfast was served about 5 hrs later. This was the first time I ever slept properly on a red eye flight and wished others did the same for late night departing flights. Of course snacks were offered anytime, but I think everyone in J just went to sleep right after take off.
