A new island emerges from the waves to join Japan's southern Ogasawara chain.
The island was created by an erupting undersea volcano filmed by the Japanese coast guard.
It's just 200 metres in diameter but the powerful eruption sent plumes of smoke almost 600 metres into the air.
Japan's government spokesman welcomed the arrival of the new territory but said it was too early to consider naming it.
(SOUNDBITE)(Japanese) JAPANESE CHIEF CABINET SECRETARY YOSHIHIDE SUGA SAYING:
"In the past there have been such instances but those islands caused by an undersea volcano then sank again so we'll be watching to see what happens."
If the new arrival survives it'll join Japan's estimated 6, 000 islands.
It would technically be part of Tokyo even though it's more than 1, 000 kilometres away.
