is a Jōdo-shū Buddhist temple in Tokyo, Japan. It is the main temple of the Jōdo-shū ("Pure Land") Chinzei sect of Buddhism in the Kantō region,. Its mountain name is San'en-zan (三縁山). Zōjō-ji is notable for its relationship with the Tokugawa clan, the rulers of Japan during the Edo period, with six of the Tokugawa shōguns being buried in the Taitoku-in Mausoleum in the temple grounds. Also, the temple's Sangedatsumon (main gate) is the oldest wooden building in Tokyo, dating from 1622. The original buildings, temples, mausoleums and the cathedral were destroyed by fire, natural disasters or air raids during World War II. It is located in the Shiba neighborhood of Minato. The Shiba Park is built around the temple, with the Tokyo Tower standing beside it. In 2015 a Treasure Gallery was opened on the underground level of the Daiden (great hall), and it currently houses paintings of Kanō Kazunobu and a model of the Taitoku-in Mausoleum. History Shūei (宗叡, 809-884), a disciple of Kūkai, founded a temple named Kōmyō-ji (光明寺) at Kaizuka (貝塚, present-day Kōjimachi in Chiyoda, Tokyo); it is said to have been the forerunner of Zōjō-ji. In 1393, during the Muromachi period, the temple, under its abbot Yūyo Shōsō, converted from Shingon to the Jōdo school. Shōsō is thus regarded as the founder of Zōjō-ji. Together with Kan'ei-ji, during the Edo period Zōjō-ji was the Tokugawa's family temple. Tokugawa Ieyasu had the temple moved, first to Hibiya, then in 1590, at the time of expansion of Edo Castle, to its present location. With the fall of the Tokugawa shogunate, the grounds took on the character of a public park. The temple was badly damaged in World War II, but still retains the air of a major temple. Architecture At its peak the temple grounds had more than 120 buildings, but following the decline of Buddhism during the Meiji period (1868-1912), most of them burned during the Bombing of Tokyo in World War II. Reconstruction began after the war, with the Daiden (great hall) being rebuilt in 1974. Sangedatsumon The 21 meter (69 foot) two-storied main gate, was constructed in 1622, and it is therefore the oldest wooden building in Tokyo. The temple's only original structure to survive the Second World War, it has been designated an Important Cultural Property. "San" (三) means "three", and "Gedatsu" (解脱) means "Moksha".
