Source-derived summary

Fūma Kotarō (風魔 小太郎) was the name adopted by the leader of the ninja Fūma clan (風魔一党, Fūma-ittō) during the Sengoku era of feudal Japan. He was a retainer of the Later Hōjō clan. According to some records, his name was originally Kazama Kotarō (風間 小太郎).

The Fūma clan and Fūma Kotarō

The clan was based in Kanagawa Prefecture, specializing in horseback guerrilla warfare and naval espionage. According to some sources, the family has roots in the 10th century when they served Taira no Masakado in his revolt against the Kyoto government. The use of the name started with the first leader (jonin) of the clan: originally surnamed "風間" (Fūma), with a different kanji, it was later changed to homophone 風魔. Each subsequent leader of the school adopted the same name as its founder, making it difficult to identify them individually. This school was in the service of the Hōjō clan of Odawara.

Fūma Kotarō was the fifth and the best known of the Fūma clan leaders. Born in Sagami Province (modern Kanagawa Prefecture) on an unknown date, he became notorious as the leader of a band of 200 Rappa "battle disrupters", divided into four groups: brigands, pirates, burglars and thieves.

Editorial summary

“Fūma Kotarō” enters the record as ninja leader. Crown Archives preserves that source wording while asking what Fūma, Kotarō and ninja can confirm, complicate or overturn.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 201-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1505. Its strongest next move is a source search built around Fūma, Kotarō and ninja.
Editorial analysis

Why this record matters

“Fūma Kotarō” is worth following because a concise public description often conceals a longer documentary argument. Here, Fūma, Kotarō and ninja provides the most credible route into that argument.

Evidence profile

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
