紀伊半島と淡路島の間に浮かぶ小さな孤島、友ヶ島の写真集です。
友ヶ島は旧日本軍が軍事拠点として利用していた島で、砲台跡などの戦争の痕跡を見る事が出来ます。

It is a photograph collection of the small solitary island which appears between Kii Peninsula and Awaji-shima, and Tomoga-shima.
Tomoga-shima is an island which Japan's now-defunct Army used as an arm site, and can see the trace of war of the remains of a gun battery, etc.
