A tantou made by Awataguchi Yoshimitsu. One of the Toushirou brothers. They say he's named Hakata Toushirou because he came from Hakata*. He came into the posession of the Ogasawara family as a gift bestowed by Kuroda Tadayuki, master of the Fukuoka Castle, to Ogasawara for their faithfulness. He inherited his merchant soul from the wealthy merchants of Hakata.
