Hakuyu Taizan Maezumi (1931-95) was a Japanese Zen Buddhist teacher and roshi, and lineage holder in the Soto, Rinzai and Harada-Yasutani traditions of Zen. He combined the Rinzai use of koans and the Soto emphasis on shikantaza in his teachings, influenced by his years studying under Hakuun Yasutani in the Harada-Yasutani school. He founded or co-founded several institutions and practice centers, including the Zen Center of Los Angeles, White Plum Asanga, Yokoji Zen Mountain Center, and the Zen Mountain Monastery. Taizan Maezumi left behind twelve Dharma successors, appointed sixty-eight priests and gave Buddhist precepts to more than five hundred practitioners. Along with Zen teachers like Shunryu Suzuki-roshi, Seung Sahn Dae Soen Sa Nim, and Venerable Hsuan Hua, Maezumi greatly influenced the American Zen landscape. Several Dharma Successors of his-including Tetsugen Bernard Glassman, Dennis Merzel, John Daido Loori, Jan Chozen Bays, Gerry Shishin Wick, Charlotte Joko Beck, and William Nyogen Yeo-have gone on to found Zen communities of their own. Maezumi died unexpectedly while visiting Japan in 1995.
