Steam+Vents

Very similar to geysers, there are areas in Hakone where holes release great amounts of steam that come from volcanoes. Because Mt. Fuji is still classified as an active volcanoe, the volcanic steam there is a result of rainwater seeping into cracks and being warmed by the lava. The steam can also be caused by underground water reservoirs coming in contact with the molten rock. Hakone brings in crowds of tourists and locals that come to witness the beautiful steam coulds that cover the land around the vents. What makes them even more spectacular is how they vanish within seconds upon cooling from the temperature change. Though the steam doesn't last long at all, it is still dangerous to stand over the vents and paths keep those that are too curious out of harms way.
