The question is in the title. Iv’e tried so many different sites, and none of them has Japanese subtitles. I would really aprecciate it!
Edit: Thank you for all the answers! I started using asbplayer as u/asdgodskf12asofk134 suggested, and it’s great.

Animelon.com (limited anime selection)
or Zoro.to + asbplayer + JP subs
Netflix has Japanese subtitles for the shows they produce (but not for series like Attack On Titan which they license from other companies).
languagereactor.com has a list of which Netflix shows have JP subs, in your region.
Animelon has series with JP subs.
