Dai Bai Zan Cho Bo Zen Ji () is a Rinzai-style Zen temple located on North Beacon Hill in Seattle, Washington. Its name translates from Japanese as "Listening to the Dharma Zen Temple on Great Plum Mountain."
Dai Bai Zan Cho Bo Zen Ji was founded by Zen Master Genki Takabayashi in 1983. Genjo Marinello Oshà  succeeded Genki Rà Âshi in 1999 as the second abbot of Chobo-ji.
Genki Takabayashi RÃ Âshi was invited by the Seattle Zen Center (founded by Dr. Glenn Webb, at the time a University of Washington Art History professor) to become the resident teacher in the fall of 1978. He accepted, and by 1983 founded Cho Bo Zen Ji. In Japan, he trained for nearly twenty years at Daitoku-ji, one of two parent Rinzai school temples. Takabayashi also directed a Rinzai temple in Kamakura. He became a monk at age 11. In 1997, Takabayashi retired and moved to Montana. Genki died on February 25, 2013, at his home in Montana, at the age of 81.

From 1981-1982 he trained at Ryutaku-ji in Japan with Sochu Rà Âshi and Soen Nakagawa Rà Âshi. Marinello later continued his training with Eido Shimano Rà Âshi, abbot of Dai Bosatsu Monastery. On May 21, 2008, Marinello received dharma transmission from Eido Shimano Rà Âshi, in a ceremony also involving his former teacher Takabayashi.
