Keizan Scott Roshi – Founder and Teacher

Rev Dr David Keizan Shoji Scott is the founder and leader of the StoneWater Zen Sangha. He is an ordained Buddhist priest and lineage holder in the Soto Zen school, having received Shiho (Dharma transmission) from Tenshin Fletcher Roshi in October 2009. Keizan is also a widely published writer on Japan, Zen Buddhism, comparative religion and cookery.

After gaining a doctorate at Manchester University, he left academic life to travel and write. He went to Okinawa in 1974 where he studied karate with Master Kanei Uechi at the dojo in Futenma. On his return to Liverpool, he started his own dojo and founded the Uechi-Ryu Karate Association (Great Britain).

Roshi has been a Zen practitioner with White Plum Asanga since 1982, intially under the guidance of Genpo Merzel Roshi of the Kanzeon Sangha.
In 2002 he was given the rank of Hoshi (“Dharma holder”) by Genpo Roshi.
In 2006, he was ordained as a monk by Genpo Roshi at the Kanzeon Zen Centre in Salt Lake City, Utah, and he was authorised by Genpo as a Big Mind facilitator.

In November 2008, Keizan formally became a student of Tenshin Roshi who he had by then known for fifteen years, and was ordained as a priest by Roshi at a Denkai ceremony at Yokoji Zen Mountain Center, California. This qualified him to give Jukai (precepts) and Shukke Tokudo (ordination).

In October 2009, Tenshin Roshi recognised Keizan as a lineage holder in a Dharma transmission ceremony in Liverpool. He was given the name “Keizan Shoji”.

In 2014 Keizan was nominated and elected as a full board member of White Plum Asanga and is acting representative for Europe including the UK.
