à Âmori Sà Âgen was a teacher of Kashima Shinden Jikishinkage-ryà « swordsmanship, and a calligrapher in the Taishi school of Yamaoka Tesshà «. He became well known for his unique approach to Zen practice integrating insights from his martial and fine arts training with traditional Zen methods; this approach has been described as a unity of Zen, Ken ("sword", referring to martial arts or physical culture), and Sho ("brush", referring to calligraphy or fine arts).
à Âmori founded Seitai-ji monastery in Japan and Daihonzan Chozen-ji in Honolulu, Hawaii, the first Rinzai headquarters temple established outside Japan according to Rinzai canon law.
Dharma successors and descendants of Omori Roshi are active in both Japan and the West. In the United States, along with Chozen-ji, successors of its first abbot, Tanouye Tenshin Roshi, established Chosei Zen (formerly Chozen-ji Wisconsin Betsuin) in Madison and Spring Green, Wisconsin, and elsewhere. Successors of Hosokawa Dogen Roshi established Daiyuzenji in Chicago, and Korinji in Reedsburg, Wisconsin. In Germany and Austria, there are active groups connected to Sasaki Gensà  Rà Âshi and Hozumi Genshà  Rà Âshi.
à Âmori is the author of more than 20 books in the Japanese language, including Sanzen Nyumon, which was translated into English and published as An Introduction to Zen Training in 2002. The book is considered a foundational text for Zen students training in the Chozen-ji tradition of Rinzai zen.
à Âmori was also well known for his right-wing ultra-nationalist political activism and influence in government circles prior to the outbreak of the Second World War.
