Characteristics A separate window opensReferences

These are the waters in the vicinity of Hegurajima Island vicinity (about 50 km north of the Noto Peninsula in Ishikawa Prefecture) While the northern side has numerous cliffs and shore reefs, the southern side has a gentle slope, with fishing harbors and sandy beaches. Sargassum beds have formed in the vicinity of Hegurajima Island, and although extensive surveys have not been conducted it is thought that numerous rare warm-water species may be distributed here (Ministry of the Environment, 2001). A diver reports that these highly productive waters are rich in abalone, turban shell, wakame, agar, and others (Hokkoku Shimbun Publishing Bureau, 2010). Hegurajima Island also is an excellent resting place for birds migrating between the Asian continent and the Japan archipelago, making it one of Japan’s leading bird-watching destinations. About 300 species of birds have been confirmed here.
