About Zen Community of Oregon

Zen Community of Oregon is a Zen Buddhist community in the lineage of Taizan Maezumi Roshi (1931-1995). Leaving Japan for the United States, Maezumi Roshi’s life vow was to plant the Dharma deeply in the soil of North America.

Led by teachers Jan Chozen Bays Roshi and Hogen Bays Roshi, the primary purpose of Zen Community of Oregon is to express and make accessible the wisdom and compassion of the Buddha’s teachings, as transmitted through an authentic, historical lineage and to support and maintain Zen Buddhist practice in order to realize and actualize our Buddha nature in everyday life.


Great Vow Zen Monastery in Clatskanie, Oregon serves as a place for residential monastic training and retreats open to the public. Heart of Wisdom Zen Temple in Portland, Oregon provides a place of practice geared to people balancing daily work, school, and families. We maintain connection with our sister Sanghas, the Corvallis Zen Circle in Oregon, Tri-Cities in Washington state, and the North Shore Zendo in Vancouver, British Columbia.


There are a multitude of ways to practice Zen Buddhism with ZCO. Regular meditation, one-on-one or group interaction with a teacher, workshops and talks, peer-led Dharma discussion groups, and short and long silent mediation retreats are offered.
