Kenchō-ji
Kenchō-ji (建長寺) is a Rinzai Zen temple in Kamakura, Kanagawa Prefecture, Japan, which ranks first among Kamakura's so-called Five Great Zen Temples (the Kamakura Gozan) and is the oldest Zen training monastery in Japan. These temples were at the top of the Five Mountain System, a network of Zen temples started by the Hōjō Regents. Still very large, it originally had a full shichidō garan and 49 subtemples.
The temple was constructed on the orders of Emperor Go-Fukakusa and completed in 1253, fifth year of the Kenchō era, from which it takes its name. It was founded by Rankei Doryū, a Chinese Zen master who moved to Japan in 1246, spending some years in Kyushu and Kyoto before coming to Kamakura.
