北條氏康
He employed the famous spearman Kamiizumi Nobutsuna, who founded the Shinkage-ryū swordsmanship school. He gave shelter to Sanada Yukitaka after Yukitaka was defeated by Murakami Yoshikiyo, a daimyō of Shinano in 1541. He served prominently during the attack on Yamanaka Castle, held by Hōjō Ujiyasu, and when he defended Minowa Castle against Takeda Shingen for no less than seven years. The records of Chōnen-ji, the temple where Nagano was buried, dates his death to 1566. Only after his death did the castle fall to Shingen.
