Dear Yurika. I really don't mean to be rude to you, but I strongly disagree with your remarks.
In your post, You wrote "Japan is an island country and Japanese was the only tribes who lives in Japan" . I have to say. That's absolutely wrong. What about the Ainu, the Ryukyuan and etc. ? The Ainu have been living in Japan since the Jomon period. I am not an ethnology expert, but still, I know there are so many people who were never told their true identity by their parents in order to protect their children from the discrimination against them. I think this widespread belief of Japan was/is an ethnically homogeneous country is nonsense.
