Year 1606 ( Keicho 11) showed in the family tree of the Ishizaki`s can be said the age to recover or open Okikamuro. About this time, The Kono`s in Iyo finally collapsed in 1588 after long battle. It is the year that the party of the Kono`s went downfall, so that many senior vassal and retainers left away from the domains of the Kono`s in several places in Suho-Oshima ( Yashiro island ). Obiously, we cannot tell the history of Okikamuro unless watching the history of the battles between the pirates such like Kono pirate (Suigun = marine), Murakami pirate ( Suigun) , Kutuna pirate (Suigun) in mainly the Seto Inland Sea or Kumano, Geishutakeda and Ugashima (Ukishima) in west and east.
There were many pirates occupies about 3000 islands in Seto Inland sea. .It is very hard to explain in details about those battles or internal troubles in old ages. I like to explain the history simply to avoid unfocused detail explanation. As you know, Sekigahara battle (Biggest battle inside of Japan between West and East power.) happened in 1600 (Keichou 5). It was the milestone of the history and year 2000 (Hesei 12) is just 400 years from it. It is the beginning for Tokugawa Bakufu(government) to establish the steady organization. At the sametime, Mori-han(prefecture) was reduced size to 2 state of Bouchou area (after losing that war). The 400 years anniversary of the establish was celebrated not only in Okikamuro in Yamaguchi prefecture, but also in many other prefectures in Japan even it’s subject was slightly different.
The Battle at Kamuro
The middle century back to about 260 years from above age(Sekigahara war), there was Kamuro Battle in Nanbokuchou age. In 1339 (Engen Gannen Japanese calendar year),it was the battle between Hokucho group like Michiharu Kono, Hosokawa and the Allied Forces of Shingen Takeda and Nanchou group organized by Yoshinori Kutsuna and Mochifusa Reizei who was the general. Okikamuro in around of Ooshima which was controlled(Command of the sea) by Yoshinori Kutsuna who possessed Iyo Kutsuna seven islands (Nokutsu island, Mutsuki island, Naka island, Futakami island, Nuwa island, Tsuwa island and Hashira island) was raided by the pirate of Hokucho group. The reason was that Hokuchou pirates group attached to shot out and blockade the ships to escort Seisei Kanenaga Imperial Prince who lived for 3 years in Naka island of Kutsuna seven islands in Iyo prefecture to Kyushu prefecture. The battle of both opposing armies finished without the end and moreover Michishige Doi and Michimoto Doi were killed.
The Battle at Minase island
10 years after that , Yoshinori Kutsuna reversely attached Takeda army of Hokucho group in Aki prefecture at Minase island in 1349(Seihei 4). In another opinion, it is described it was done at Kamuro island, Yuri island, Oominase island or Kominase island.
