[@Zero Hex] It'll be set in NotJapan which is different than NotChina and whatnot, but we'll say the people have been substantially less xeonophobic and there's been a good amount of cultural diffusion to account for Chinese inspired people living in Japanese inspired places.

There's actually a part of Japan that historically had a lot of chinese influence, it was the Ryukyu Kingdom. A stretch of islands that reach all the way to Taiwan and of which Okinawa is the most important of the lot, though it was a vassal state to Japan it kept its own monarchy and culture and its position afforded it plenty of contact with China, which it used to be a vassal state of actually. Since it looks like making a mongolian might be a bit of a hassle I was thinking of doing a little writeup on NotRyukyu anyway.
