スペイン語クラス    Conquest of Uotsurishima   Back

     
In 1884, a pioneer by the name of Tatsushiro Koga (古賀辰四郎, 1856-1918) learned from fishermen from Ishigaki Island that the Senkakus were so awash with albatrosses that there was almost no room to set foot ashore.

In the same year, the Japanese government finally gave permission to Tatsushiro Koga to develop the islands, although he had already gone ahead and made his workers collect feathers of ahō-dori without official mandate. However, the governmental support only served to spur Tatsushiro's high-flying ambitions. In 1897, he had his workers relocate to Uotsurishima (魚釣島), and in 1898 to Kubashima (久場島), to capture 150,000-160,000 albatrosses, dramatically slashing their population.

In the following year, the Japanese government leased Uotsuri-shima, Kita-kojima, Minami-kojima, and Kuba-shima to Koga for 30 years at no cost. In 1918 Tatsushiro Koga died and his son succeeded him in the work of developing the islands. In 1926, after the 30 year lease had expired, the Japanese government changed the arrangement to require an annual renewal of the lease and imposed a rental fee. In 1932, Koga junior entreated the Japanese government to sell the islands, purchasing four of them himself.

In the 1970s, Koga Tatsushirō's descendents Zenji and Hanako Tatsushirō sold four islets to the Kurihara family of Saitama Prefecture. Hiroyuki Kurihara owns Uotsuri, Kita Kojima, and Minami Kojima. Hiroyuki's sister owns Kuba.
