Kuroda Nagamasa
In 1600, Kuroda Nagamasa received huge rewards in the form of land in Chikuzen Province for his contributions during the Battle of Sekigahara and moved into Najima Castle (名島城 Najima-jō) to form the Fukuoka han. Najima Castle had been created by Tachibana Akitoshi and was expanded by Kobayakawa Takakage, but was much too small to accommodate a large han, leading to the selection of Fukusaki hill as a new castle site.
