In this manuscript, I reviewed the domestic situation of Japan in the year of 1350 and the sequential relationship of the international situation of East Asia which was closely related mutually. And I mentioned the chain of command and the headquarters of Waegu(japanese pirates) in Tsushima island Japan. I considered the international situation that Koryo dynasty had attacked Tsushima in the year of 1389. By these consideration, I confirmed that waegu is not the simple pirates for all the world but the corsail, which was associated with the domestic situation of three nations(元․高麗․日本) of East Asia and with the mutual relation of between three nation.
