I'm with the above poster, @SpookyTed. Japanese, Chinese and Korean [which Korea, anyway?] are all very distinct cultures with very distinct identities. You have to be careful with conflating all three together like this, those nations have a horrible history of being mixed up with each other.
Better to just pick one, depending on what's available to you.
If you're using MV, the MV Trinity Resource Pack has tilesets themed for China and Japan. It has a lot of other stuff in there too, so I think the price is well worth it, especially if you intend to make use of the RTP.
I genuinely like the default MZ actor sprites, and the character creator. I think I will draw new headshots for them, but part of me doesn't want to replace the default sprites. But should I? I want to eventually release my game.
