It is said that the residents of Mito in Ibaraki Prefecture exhibit three ishes (水戸の三ぽい mito no sanpoi):
Rikutsuppoi: churlish
Okorippoi: snappish
Honeppoi: mulish
Sometimes you also hear akippoi, coquettish. If you regularly display all three ishes in the area, you may be called Mitoish (水戸っぽ mitoppo).
A psychologist once encountered the snappish folk of Mito on a crowded bus. As it pulled up to a stop where more people were waiting, the driver announced, “Folks in the middle, pack it in please!” Said the churlish passengers, “Hey, pops, which way are us people in the middle supposed to pack it in?” Everyone laughed.
It is unknown whether the three ishes of Mito are flaws or merits.
