Aokigahara Aokigahara (青木ヶ原 ) , also known as the Suicide Forest or Sea of Trees (樹海 , Jukai ) , is a forest on the northwestern flank of Japan's Mount Fuji thriving on 30 square kilometers (12 square miles) 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 filled with ice, is a popular destination for tourists and school trips. Parts of Aokigahara are very dense, and the porous lava absorbs sound, helping to provide visitors with a sense of solitude.

Pillow lava has been sampled on the north west flank of Koko Seamount, and the oldest dated lava is 40 million years old. Seismic studies indicate that it is built on a 9 km thick portion of the Pacific Plate. The oldest rock from the north side of Koko Seamount is dated at 52.6 and the south side of Koko at 50.4 million years ago. To the southeast of the bend is Kimmei Seamount at 47.9 million years ago and southeast of it, Daikakuji at 46.7.
