Tenkai

Tenkai (Japanese: 天海; 1536–13 November 1643) was an influential Japanese Tendai Buddhist monk of the Azuchi-Momoyama and early Edo periods. He achieved the rank of Daisōjō, the highest rank of the Tendai priesthood and was an influential advisor to various Shoguns, including Tokugawa Ieyasu. He also oversaw the project to carve and print the Kan'ei-ji Edition (also known as Tenkai Edition) of the Chinese Buddhist Canon, which was completed in 1648.

His Buddhist name was first Zuifū (随風), which he changed to Tenkai in 1590. Also known as Nankōbō Tenkai (南光坊 天海), he died on 13 November 1643, and was granted the posthumous title of Jigen Daishi (慈眼大師) in 1648.
