I work kinda similar hours in Japan - sometimes I have meetings with US even later at night like 1-2 AM, other days I have 0 meetings and can work whatever time I want. maybe on average I work 12 PM - 7 PM or so. here it works totally fine because people start going out late and stay out late - even on a weekday there are lots of bars that open at 8 PM and close at “4 AM” (but will stay open later if people want). also I live in Central Tokyo, plenty of tourists and other international expats who have a late sleep schedule to hang out with. in SEA probably Bangkok would have the most similar vibe - I’ve definitely stumbled across random bars in neighborhoods like Thong Lor (expat central) at 12 AM and had fun drinking there until 2-3 or whatever.
