Don't even think about refering us as those stinkin japs.
That yellow district is Kaya, and it has no ties with Japan. Except for imjinwaeran period, the japs have never invaded or colonized Korea. But remember the korean paekche kingdom invaded and conquered parts of the Japanese island in 369-375 A.D. they used korean and maybe chinese swords while they were fighting the Yayoi. After taking quite a bit of territory a korean prince named Homuda esatblished a new kindom called Yamato after the Yamato river in the head of Osaka Bay. According to the Japanese chronicles, the court of the Yamato kings was based on Korean models for the titles given to the court and regional aristocrats were drawn from Korean titles.
