The Shôni of Hizen province were descended from Fujiwara Hidesato, one of whose descendants received the title Dazai Shôni from Minamoto Yoritomo and settled at Dazaifu and took the name Shôni. The Shôni played a key role in the Mongol Invasions and later served under Ashikaga Takauji (after initially supporting Emperor Go-Daigo). They initially lost their domain in the Sengoku Period to the Ôuchi but managed to regain them with the help of the Ôtomo. In 1553 their erstwhile vassal Ryûzôji Takanobu rebelled and by 1559 they had been completely destroyed.
