For a week, these rocks have washed up on the beaches of the islands in the southwest of the country.
According to several Japanese media, the phenomenon is the consequence of an underwater volcanic eruption that occurred in August off the Ogasawara archipelago in the Pacific.

Stones paralyze ports and prevent boats from going out to sea. They also affect fishing.
In Okinawa Prefecture, clearing work began on Friday on the island's beaches and ports.
