I believe Moomins (楽しいムーミン一家) was animated in Japan so that will count if that was the criteria.

Also TB2086 aka 科学救助隊テクノボイジャー (whatever that means).

They're more kids/teen shows but I'm not into what most western people classify as anime.

 

Also it goes without saying that the Japanese versions of these may not be quite what I have seen. eg. They often seem to have very different intro songs there that bear no resemblance to what I heard. This matters since I really like the audio and music work in both.
