God I fucking love Church of Misery, Japan has an incredible doom metal scene btw, look into it, couple quick off the cuff recs are bands like King Goblin, Birushanah, Coffins, Black Lab, and Corrupted. Pretty heavy death metal influences on most of these, but you shouldn't be surprised to see that from me lol. That said, there exists plenty of straightforward psych/stoner stuff from Japan too, the biggest issue I've noticed is a lot of Japanese bands don't get their catalog on all the streaming services. You're usually lucky to find them on spotify and maybe bandcamp.
