Located southeast of the Mieidō, the Kyōzō was constructed in 1621, the same year as the Sanmon. The architecture is a mixture of Japanese and Chinese styles and presents a unique stylistic beauty. In contrast to the subdued exterior, the interior is alive with color and the ceiling and wall paintings by the Kanō School are precious. Also, in the middle is an octagonal sutra wheel which contains the Sung Chinese edition of the entire Buddhist scriptural canon in six thousand volumes, donated by the second Tokugawa shogun, Hidetada. It is said that if you turn the sutra wheel once, you can gain the same benefits as if you actually read all of the sutras.
