Hateruma, which is composed of corals, has 12.7 km2 of area and approximately 600 inhabitants.
The primary products of the island include sugarcane, pineapple, refined sugar, and Awanami, a highly prized type of the alcoholic beverage awamori.[1] Its southern location makes it one of the few places in Japan where the Southern Cross can be observed.
Sights
Hateruma is visited by a comparatively high number of Japanese tourists from Ishigaki on day trips, as it boasts the southernmost tip of land of Japan. In addition, the southernmost school and the southernmost police station of Japan are tourist attractions. Further places of interest include:
- In the only village, several well-preserved old houses showing the traditional architecture with a hip roof, red tiles and a shisa statue on the top can be seen. Many old houses are still surrounded by a thick wall consisting of dark coral stones.
- In the village center, there is a memorial to Oyake Akahachi, a rebel who was born on Haterumajima around 1500. The memorial was erected on a platform of coral stones.
- One of the most interesting buildings on Haterumajima is the old watchtower Kodomori dating from the 17th century. It was used for observing the ships sailing to and from Ishigaki. As the top of the tower was one of the highest points of the flat island, it was used for smoke signals and for signal lights. A similar tower, which is called Puzumari, can be visited on the neighboring island Kuroshima.
- On the south coast, there is a memorial indicating the southernmost tip of land of Japan. The south coast is steep and the sea is very rough there.
- The north coast of Haterumajima is a favorite tourist destination, because of its fine sand.
