Looks a bit like Mt. Fuji, doesn't it?

Owakudani (lit. "Great Boiling Valley") is a volcanic valley in Hakone. The active vents spew sulfur into the air, making all the asthmatics quake in their booties. Though nowhere near as large or impressive, Owakudani was very reminiscent of Mount Aso in Kumamoto Prefecture, Kyushu.
