He was given to Tadazane Ogasawara by Tadayuki Kuroda, the lord of Fukuoka Castle in the Chikuzen province, and has since been passed down through the Ogasawara family. He harbors the spirit of the wealthy merchant of Hakata who inherited him.
Hakata Toushirou was purchased by Japan's Agency for Cultural Affairs in March 2017, as a part of a program aimed at preservation of Cultural Properties. (An unverified tweet reported the purchase price was 83 million yen (approximately US $750,000.))
Some fanworks depict Hakata with Heshikiri Hasebe and Nihongou. This is due to Hasebe being given to Yoshitaka Kuroda, or his son, Nagamasa Kuroda. Nihongou, however, was won by Fukushima Kuroda after winning a drinking bet. These three together are know as Kurodagumi.
