History The temple founded in 1380 by Nikaidō Sadafuji, the shugo of Kai Province, who invited the noted Zen prelate Musō Soseki from Kanagawa to build a hermitage on his property. Due to the fame of Musō Soseki, it became the center for the dissemination of Rinzai teachings in Kao Province, and was name one of the Kantō Jissetsu by Shogun Ashikaga Yoshimitsu. However, the temple fell into ruin during the Onin War. It was revived in the Sengoku period by Takeda Harunobu in 1541. Takeda Shingen made Kaisen Joki head priest in 1564. In 1582, Kai Province was invaded by an alliance between Oda Nobunaga and Tokugawa Ieyasu. Eirin-ji was accused of sheltering Rokkaku Yoshisuke (a former enemy of the Oda), and the temple was completely destroyed. After Tokugawa Ieyasu became master of Kai Province, he ordered that the temple be rebuilt and in 1672, memorial services for Takeda Shingen were held. The temple continued to honor its connection with the Takeda clan through the Edo period and even after the Meiji restoration. Most of the Edo period structures were lost in a fire of 1905.
