Eisai， also read Yo^sai ヨウサイ; Japanese Zen monk （1141-1215）， considered to be the founder of the Rinzai sect 临济宗in Japan. Born into a family of the Shinto priesthood， Eisai began to study Buddhism at a young age， mainly the Tendai teachings of Mt. Hiei 比睿山. There， he became disillusioned with the venal agendas of the leading priests， and sought to travel to Song China to encounter the true teachings. He stayed less than a year， but receiving a strong impression， returned to Mt. Hiei carrying a large volume of Tendai texts. He later moved to Kyushu to teach and practice， but again traveled to the Song at the age of forty-seven （1187）. This time he also attempted to travel further to India， but was unsuccessful due to political hindrances. During this second period， Eisai met Xuan Huaichang 虚庵怀敞， a master of the Huanglong 黄龙 school of Linji Chan and became his student. Four years later （1191）， after received certification of his enlightenment from Huai-ch'ang， Eisai returned to Japan， where he established the first Zen temple in Japan， 圣福寺. He was able to work again in the Kyushu area， but due to the insecurities of the Mt. Hiei establishment he was prevented from teaching in the capital. Eisai responded by moving to Kamakura， where the newly founded Shogunate welcomed the prospect of a new， unsullied religious tradition， offering their full patronage， and supporting him in the construction of Kenninji 建仁寺 in Kyoto. Eisai passed away at 75， after the completion of one more temple， the Jufukuji 寿福寺， in Kamakura. He is credited with the introduction of tea cultivation in Japan， writing a book on the topic， called ， which addressed the medicinal virtues of tea-drinking. Other works include the Bodaishinron ko^ketsu 菩提心论口诀， Ko^zengokoku ron 兴禅护国论， Shukke daiko^ 出家大纲， in addition to works on Tendai 天台 and Mikkyo^ 密教. Ease， comfort （sukha）.
