Mr. Kurushima - Mr. Kurushima

In the Middle Ages, this powerful clan ruled Kurushima Island in Iyo (Ehime Prefecture). There are theories that they were a branch of the Minamoto or Kono clans, but it is said that they were a branch of the Murakami clan, a pirate clan in the Seto Inland Sea whose main base was Omishima, Noshima, Kurushima, and Innoshima. During the Muromachi and Sengoku periods, they were under the control of the Kono, Ouchi, and Mori clans, and Michiyasu worked hard to restore his master, the Kono clan, and his son Michifusa changed his surname from Murakami to Kurushima. In 1581 (Tensho 9), Michifusa joined Hashiba Hideyoshi (Toyotomi Hideyoshi), and later played an active role in Hideyoshi's conquest of Shikoku, becoming a daimyo with a stipend of 14,000 koku. His son Yasuchika sided with the Western Army in the Battle of Sekigahara, and in 1601 (6th year of the Keicho era) he was transferred to the three counties of Kusu, Hita, and Hayami in Bungo (Oita Prefecture), and moved to Mori (present-day Kusu Town), where his son Michiharu called his name Kurushima. He inherited the Mori domain's 14,000 koku (later 1,500 koku was distributed to his family) and became a viscount in the Meiji era.

中世、伊予(いよ)（愛媛県）来島を領有した豪族。源氏または河野氏(こうのうじ)の一族との説があるが、大三島(おおみしま)、能島(のしま)、来島、因島(いんのしま)を中心とする瀬戸内海海賊衆村上氏(むらかみうじ)の一族と伝える。室町・戦国時代は、河野、大内(おおうち)、毛利(もうり)各氏の支配下にあり、通康(みちやす)は主家河野氏の復興に尽力し、子通総(みちふさ)は村上を来島と改姓したという。1581年（天正9）通総は羽柴秀吉(はしばひでよし)（豊臣秀吉(とよとみひでよし)）に属し、のち秀吉の四国征伐で活躍し1万4000石の大名となった。子康親(やすちか)は関ヶ原の戦いで西軍に味方し、1601年（慶長6）豊後(ぶんご)（大分県）の玖珠(くす)、日田(ひた)、速見(はやみ)3郡に転封となり森(もり)（現玖珠町）に移り、子通春(みちはる)以後久留島(くるしま)と称した。森藩1万4000石（のち1500石を一族に分与）を継承し明治に子爵となった。
