Kuro-shima

Kuro-shima ("Black Island"), the biggest island covering 5.3 km²,^[1] has about 650 inhabitants who are mostly the descendants of Catholics who hid here to escape persecution after the Shimabara Rebellion of 1637. The island church, Kuroshima Tenshudō, was built in 1902. It is one of the rare brick churches in Japan. It was declared an "Important National Heritage" in 1998.^[2] There are some well-preserved old houses on the island showing the traditional architecture.

Most of the island is covered by dense forest. There are a few paddy fields on Kuro-shima as well, some of them are terraces which are very rare in Japan. In the middle of the island, there is a school, an administration building and a shop. The small harbour of Kuro-shima is in the north of the island.
