- Japanese: 葛山信貞 (Katsurayama Nobusada)
Nobusada was a son of Takeda Shigen of Kai, perhaps the 6th but this is unclear. He succeeded Katsuraya Ujimoto, who died without an heir, and became the lord of Katsurayama Castle in Suruga Province.
When the Oda and Tokugawa invaded the Takeda domain in 1582, Nobusada fled to Kai and then commited suicide at the Zenkouji [善光寺] in Kofu.
