Kujukushima is an archipelago of Rias coast lined with Sasebo City in Nagasaki Prefecture and the west coast of Kitamatsuura Peninsula to Hirado City.
All former Kitamatsuura-gun. The total number of islands is now officially set at 208. This is based on the 2001 survey by the Sasebo City, etc. on the Study on the Number Survey of the Ninety Nine Islands, but there are discords with the island definition. According to the field survey by Seiji Koji, author of “Seikai National Park – Kujukushima Island and Whole Island Picture Book” (Gebunsha), there are 216 on the basis that the plants are grown independently from other land areas at high tide .
Most of them are uninhabited islands and reefs, and there are four manned islands inhabited: Kuroshima, Takashima, and Maejima and Todarishima, which can be bridged from the mainland by a bridge.
Hirado lord Matsuura Shizuyama copied the name to the Ikuta Kujukushima island in Akita Prefecture. Taitaka Ino who visited the survey has left a lyrical song, saying, “Shinjyo no Ainoura (Aigamiura Aiura) Ikuno Jukushima Ikuno Matsubara”.
On the way to the Sasa river mouth, the north side is sometimes called the north ninety nine island and the south side is the south ninety nine island. In the South Kujukushima Island, a pleasure boat Pearl Queen departs from Saikai Pearl Sea Resort in Kagoshima, Sasebo City, and marine sports such as sea kayaking and yachts are popular. It has been selected as one of Japan's 100 views.
In addition, it is also a production area of oysters (both natural and aquaculture), and events by local fishermen's cooperatives are also held in winter.
Sasebo City has designated September 19th as the day of the ninety nine islands since 1999, and has held the ninety nine island festival at the Saikai Pearl Sea Resort the day before.
On April 20, 2018, it was certified to join the world's most beautiful Bay Club.
