North Kujukushima

Japanese: 北九十九島 - きたくじゅうくしま

...A group of islands scattered from outside Sasebo Port in northern Nagasaki Prefecture along the west coast of the Kita Matsuura Peninsula for about 25 km north. They were formed by the submersion of eroded Tertiary hills, and are divided into Minami Kujukushima and Kita Kujukushima at the mouth of the Sasa River in the middle. Minami Kujukushima has about 90 small islands with unique shapes distributed over a narrow sea surface, and Kita Kujukushima has about 115 relatively large islands scattered around.

From Shikamachi [town]

...The population, which was over 20,000 at its peak, has dropped sharply, but has since attempted to recover through the attraction of factories, the cultivation of mandarins and loquats, agricultural development such as livestock farming, and the cultivation of fish and pearls. On the west coast are the Kita-Kujukushima Islands, centered around Utagaura, which are included in the Saikai National Park. Shikamachi Port is a good natural harbor where regular ships stop.
