Izumo Matsushima
Izumo Matsushima consists of over twenty rocky islets of varying sizes, formed as heavy waves eroded uplifting volcanic rhyolite rocks dating back about sixteen million years. Sargassum and other marine algae have formed dense undersea forests on the rocky seabed surrounding the islets, creating ideal habitat for reef fish such as scorpion fish (Sebastiscus marmoratus) and dark-banded rockfish (Sebastes inermis). Large schools of red sea bream (Pagrus major) and yellowtail (Seriola quinqueradiata) make Cape Hinomisaki a popular destination for visitors interested in fishing.
