Tōyama Hayato-no-suke served as a bushō during the Sengoku period. He was a retainer of the Gohōjō clan of Sagami Province.
Hayato-no-suke was born as the second son of Tōyama Tsunakage. Hayato-no-suke is an official title and his real name is unknown. He first appears in records in 1552.
Although Hayato-no-suke was the second son, his older brother, Tōkurō died early in 1547, so he became the designated successor to his father. Tsunakage maintained close relations with Hōjō Tsunanari of the Tamanawa-Hōjō so Hayato-no-suke married Tsunanari’s daughter, Jōkōin-dono.
On 1/8 of Eiroku 7 (1564), Hayato-no-suke and his father, Tsunakage, were killed in action during the Battle of Kōnodai.
A daughter, Owari-no-tsubone, who was born to his widow or consort, wed Tōyama Naokage, the lineal heir of Hayato-no-suke’s younger brother, Tōyama Masakage, who inherited the headship of the clan in the wake of Hayato-no-suke’s demise.
