Danzan-ryū: History, Events & Measurement
Danzan-ryū (檀山流) is a ryū of jujutsu founded by Seishiro Okazaki (1890–1951) in Hawaii. Danzan-ryū jujutsu is of mainly Japanese origin but is most common on the West Coast of the United States. The Danzan-ryū syllabus is syncretic and includes non-Japanese elements.
