Kenninji is a temple of the Zen sect, one of the main branches of Japanese Buddhism. Buddhism, founded approximately 2,500 years ago in India by Shakyamuni Buddha, teaches that the inherent suffering of life can be transcended through equanimity, wisdom, and compassion. The Zen sect, dating back to sixth-century China, seeks the realization of this ideal through a strict training system stressing work and meditation. At present, there are three branches of Zen in Japan - the Rinzai Soutou and Oubaku schools. Kenninji belongs to the Rinzai tradition. The temple was founded in 1202 by the priest Yousai (1141-1215).
