Shōni Fuyuhisa served as a daimyō during the Sengoku period and as the seventeenth head of the Shōni clan of Hizen Province. The characters in his name were derived from his ancestors Shōni Yorihisa and Shōni Fuyusuke (father and son) from the Nanboku and early Muromachi periods.
Fuyuhisa’s year of birth is regarded as between 1527 and 1529. Under another theory, he was born in 1510 and inherited the headship of the family in 1517. Considering that his daughter wed Yokodake Sukemasa is not inconsistent with Fuyuhisa’s year of birth in 1510 but uncertainty remains.
In 1536, Fuyuhisa was attacked by Sue Okifusa who acted upon orders of Ōuchi Yoshitaka. When his father, Shōni Sukemoto, took his own life, Fuyuhisa fled for the protection of Oda Sukemitsu (Masamitsu’s grandfather) at Hasuike Castle.
Later, Fuyuhisa received help from a band of retainers including Ryūzōji Iekane and, in 1540, revived the Shōni clan. However, in 1545, a retainer named Baba Yorichika deceived Iekane and assassinated a majority of the family. In 1546, Yorichika was, in turn, killed in a counterattack by Iekane while Fuyuhisa came into conflict with Iekane.
Thereafter, Fuyuhisa fought against Ryūzōji Takanobu (the great-grandchild of Iekane), and, in 1559, was attacked by Takanobu and Chiba Tanetsura, whereupon Fuyuhisa and his younger brother, Chiba Taneyori, took their own lives in Seifukuji Castle, marking the end of the Shōni clan.
Later, his younger brother, Shōni Masaoki, joined with Baba Akichika (Yorichika’s grandson) to raise an army for the purpose of reviving the Shōni clan, but it did not materialize.
