Ok so these are fairly famous as I think most of them were released internationally, but still:
Emerging
Billion Dogs
Kami-sama no iutoori (you said nothing over 200, but hear me out, if you put the 1st and 2nd it's only 207 chapters but I promise you they are worth it T.T it's my absolute favorite and everything in it serves a purpose)
Sennen Meikyuu no Nana Ouji
Apocalypse no toride
Starving anonymous (I recomend not reading the re:velation if you are satisfied with after reading the original)
Ajin (yes, there's even a Netflix adaptation, but if you haven't read, do read it!)
Locker room (a little one-shot)
Jaa, Kimi no Kawari ni Korosou ka? (on going)
any thing not too famous (cuz i already read most of them) and no echi or yaoi or yuri (no romance if possible) also plz dont recomend something with over 200 chapters ╥﹏╥
