life and work

Ōkubo Nagayasu was the son of the Nō actor Komparu Shichirō (金 春 七郎). He served the Takeda in Kai Province and was promoted to samurai. After the Takeda had been destroyed in 1582, he joined Ōkubo Tadachika (大 久保 忠 隣; 1553–1628), prince in Sagami Province , who gave him his family name and recommended him Tokugawa Ieyasu . Ieyasu appointed him head of the Iwami silver mines in 1601, and he greatly increased their production. As a result he was in 1603 with the gold mines of Sado Island and 1606 with those of the province of Izu , whose yield he was also able to improve. Ieyasu appointed him commissioner for Sado (佐渡 奉行, Sado Bugyō), rewarded him with the title "Iwami no Kami" (岩 見 の 守) and the domain Hachiōji in Musashi Province with an income of 20,000 Koku .

After Nagayasu's death, evidence was found in his home that he had worked fraudulently. Letters were also found that indicated a planned attack on the Shogun Tokugawa Hidetada , which was to be carried out with Christian and Spanish help. His son Tōjūrō was arrested on the spot and executed with six suspects.
