Karte von Japan, wenn alle Kanji als chinesisches Hanzi ausgesprochen würden

This is a really fun idea, and it immediately shows how much of Japanese place-name “sound” is tied up in kanji. But mapping each character to a single modern Mandarin hanzi reading is going to create some wild collisions and weirdness (multiple readings, shinjitai vs traditional, kana parts, etc.). Still, super cool visualization. Did you base the readings on modern Mandarin, or some other standard?

Feels like that “change your phone language to Dutch” meme

It’s ever so slightly similar.

north korea in chinese would usually just be called 朝鲜, nobody ever calls it 北朝鲜
