The tsunami follows a major eruption from an underwater volcano 65km south of the island nation of Tonga
A tsunami warning has been issued for Japan’s entire east coast, as well as the southern Amami island and the Takara island chain.
A tsunami triggered by the undersea volcanic eruption has already hit the Pacific nation of Tonga and prompted multiple other nations to issue warnings, including the United States and Japan.
The eruption was so big it was seen from space.
Residents were warned to evacuate from coastal and riverside areas and seek higher ground for the early hours of Sunday, January 16, with waves expected to reach as high as three meters.
Some local media reported that tsunami waves had already reached the coast of Tohoku and Okinawa early Sunday.
