New landmass about 100 metres across pops up above the waves near Iwoto island after eruptions began last month
Japan has gained another island to add to its already impressive collection, after an undersea volcanic eruption 1,200km (745 miles) south of Tokyo created a new landmass.
Experts said the tiny island emerged after a series of eruptions that began in October near Iwoto island, part of the Ogasawara island chain in the western Pacific.
