Don't have list, but since you didn't specify the genre, maybe this tag of mine may be useful for you. I like to divide my stories by their time setting thus my tag "ancient" fits your bill. It's quite a lot though so if you do have other specifications, plz tell me and I'll look for some I can especially recommend.

Any manga/manhwa where Mc travels back to past (historical) but not in European setting? I want ancient Japan or Korea pls. I’d prefer a list but individual stories are fine too
