Aokigahara (青木ヶ原, 'Blue Tree Meadow'), also known as the Sea of Trees (樹海, Jukai), is a forest on the northwestern flank of the Mount Fuji on the island of Honshu in Japan, thriving on 30 square kilometres (12 sq mi) of hardened lava laid down by the last major eruption of Mount Fuji in 864 CE. The western edge of Aokigahara, where there are several caves that fill with ice in winter, is a popular destination for tourists and school trips.
