Izu Seven Islands

Japanese: 伊豆七島 - いずしちとう

The seven islands are Oshima, Toshima, Niijima, Kozushima, Miyakejima, Mikurajima, and Hachijojima. All belong to Tokyo. All of the islands are volcanic islands in the Fuji volcanic belt. Sea cliffs have developed due to the rough waves of the Pacific Ocean, and the plains are narrow. The average course of the Kuroshio Current is between Hachijojima and Mikurajima. Although it receives a lot of rain, surface water is scarce, and water is often in short supply. The climate is marine subtropical, with warm winters and tropical forests. In the past, it was chosen as a penal colony as a remote island. Fishing, forestry, dairy farming, and horticulture have been practiced here, but it has become a tourist and recreational area. In 1955, it was designated as part of the Izu Seven Islands Quasi-National Park, and in 1964, it was incorporated into the Fuji-Hakone-Izu National Park. There are flights from Tokyo to the main islands, and boat services from Tokyo, Yokohama, Shimoda, Atami, etc., but flights may be canceled due to winter monsoons and typhoons from summer to autumn.

Japanese:

大島，利島，新島，神津島，三宅島，御蔵島，八丈島の7島をさす。いずれも東京都に所属。全島が富士火山帯に属する火山島。太平洋の荒波によって海食崖が発達し，平野が狭い。八丈島と御蔵島の間が黒潮本流の平均の流路となっている。大量の雨が降るが地表水に乏しく，水は不足がちである。気候は海洋性の亜熱帯気候下にあり，冬も温暖で，暖帯林が生育。昔は僻遠の島として流刑地に選ばれた。漁業，林業，酪農，園芸農業が行われてきたが，観光地，レクリエーション地の性格を強めている。 1955年，伊豆七島国定公園に指定，64年に富士箱根伊豆国立公園に編入。東京から主要島へ航空便，東京，横浜，下田，熱海などから船便があるが，冬の季節風，夏から秋の台風で欠航することもある。
