Kyūroku-jima, Volcanic islets in Fukaura, Japan.
Kyūroku-jima is a group of small rocky islands rising from the Sea of Japan, consisting of several distinct outcroppings of dark stone. The islands are situated in waters known for strong currents and challenging maritime conditions.
The islands were first documented on Western maps in 1855 when the British vessel HMS Bittern observed a large seal population on the rocks. This sighting marked the first known European record of the group in this Japanese region.
Local fishing communities in the area have depended on the waters around these islands for generations as a vital food source, and this connection remains part of their identity today. The sea and the islands continue to shape how people in Fukaura relate to their coast.
Visitors can best view the islands from the water, with a boat being the most practical way to see them from the coast. The rough sea conditions make approaching them challenging, so caution is necessary when planning a viewing trip.
The islands display dark volcanic rock and yellowish mineral deposits marking the peaks of an ancient submarine volcano. This geological formation reveals thousands of years of hidden regional geology in visible form.
