Danzan-ryū
Hawaiian martial art of Japanese origin

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.
History
Seishiro Okazaki was born in Fukushima Prefecture, Japan in 1890. In 1906, he immigrated to the island of Hawaii. Soon after, he was afflicted with a pulmonary condition which may have been tuberculosis. During this time, young Okazaki began studying under a Yōshin-ryū jujutsu sensei by the name of Yoshimatsu Tanaka in Hilo, Hawaii. Okazaki assiduously pursued his studies under Tanaka and after some time found that his respiratory condition had gone into remission. Okazaki felt that the study of martial arts had played a large role in his physical recovery and as a result, he decided to dedicate his life to the study and teaching of jujutsu and related disciplines.
Okazaki later adopted the Western first name, Henry.

Why this record matters
“Danzan-ryū” is worth following because a concise public description often conceals a longer documentary argument. Here, Danzan-ryū, Hawaiian and martial provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q5221457. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1890, 1951 and 1906.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
