Harada-Yasutani (also known as The Sanbo Kyodan or “Three Treasures”) school of Zen was established in Japan by D.S Harada Roshi and his student and close collaborator H.R.Yasutani Roshi. The school, one of the most energetic and iconoclastic Buddhist organizations in the post-war Japan, combines elements of Japanese Soto (esp. teachings of Dogen Kigen and his Dharma grandson, Keizan Jokin) and Rinzai (esp. teachings of Hakuin Ekaku) traditions while its ‘graduates’ constitute the lion share of all Zen teachers currently active in USA, Germany, Switzerland, Philippines and Australia.  Dharma Heirs and Teachers of the Harada-Yasutani school:
