The three traditional schools of Zen in contemporary Japan are the Sōtō (曹洞), Rinzai (臨済), and Ōbaku(黃檗)…

Of these, Sōtō is the largest, Ōbaku the smallest, with Rinzai in the middle. These schools are further divided into subschools by head temple, with two head temples for Sōtō (Sōji-ji and Eihei-ji, with Sōji-ji having a much larger network), fourteen head temples for Rinzai, and one head temple (Manpuku-ji) for Ōbaku, for a total of 17 head temples. The Rinzai head temples, which are most numerous, have substantial overlap with the traditional Five Mountain System, and include Myoshin-ji, Nanzen-ji, Tenryū-ji, Daitoku-ji, and Tofuku-ji, among others.
