Everything you are talking about regarding Japanese citizenship is true, although you are framing it as if it's something that is written in stone and immutable. Some of the ethnic Koreans in Japan are descendants from the Koreans that were __forcibly__ moved to Japan during Japanese occupation pre-WW2. It would only make sense to have some special exceptions for them. The occupation ended, and they didn't choose to be there in the first place. EDIT: regarding the ethnic Koreans forced labor in Japan, see this reference : https://en.wikipedia.org/wiki/Slavery_in_Japan#World_War_II https://en.wikipedia.org/wiki/Slavery_in_Japan#World_War_II [...] 670,000 Koreans, were conscripted into labor [...], about 60,000 died [...] Many were stripped of their nationality and denied repatriation by Japan.
