Noshima Murakami
From Wikipedia, the free encyclopedia

The Noshima Murakami were a Japanese family, involved in seafaring and piracy during the 16th century.[1]: 221 The family was based on Noshima, a small island off the coast of Shikoku in the Seto Inland Sea.[1]: 223
In 1532, the Noshima began working for the Ōtomo clan and the Kōno family, who were fighting against Ōuchi Yoshitaka. They attacked Ōuchi sea lords in the Kamagari Islands.[2]: 111 In the summer of 1541, Ōuchi's Shirai sea lords led an attack against the Noshima, Kurushima, and Innoshima, reaching a standstill in the winter months.[2]: 111–2 The next year, the Noshima began to conduct cargo inspections at Itsukushima under a contract with Ōuchi Yoshitaka.[1]: 230 This led the Kōno family to stop their patronage.[1]: 230 Merchants from Sakai brought a suit against them alleging an infringement of their rights to levy duties. A countersuit was brought by the Noshima, and the merchants acknowledged their toll rights on all ships apart from those coming from south Kyushu.[1]: 230
In the 1540s, a minor branch of the family based on the nearby Nakatoshima island launched a challenge over house leadership.[2]: 113 Ōuchi sponsorship and assistance from the Shirai allowed the main branch to subdue them easily.[2]: 113–4
