Kyōzō (経蔵) in Japanese Buddhist architecture is a repository for sūtras and chronicles of the temple history. It is also called kyōko (経庫), kyō-dō (経堂), or zōden (蔵殿). In ancient times the kyōzō was placed opposite the belfry on the east–west axis of the temple. The earliest extant kyōzō is at Hōryū-ji, and it is a two-storied structure. An example of one-storied kyōzō is at Tōshōdai-ji in Nara. A kyōzō's usual size is 3 x 3 ken.
