Daisetsuzan 2019: Steam Vents

At the base of the west side of Mt Asahidake are steam vents that are continuously spewing volcanic gases. A short trail leads up to nearby the vents where you can get a better look at them. Although Mt Asahidake hasn’t erupted in almost 300 years (the last eruption is theorized to have happened in 1739) the steam vents are testaments to the fact that volcanic activity is still going on underground. The gases coming out of the vents have a nasty smell, though you’ll notice it most when climbing the mountain since you’ll have to pass through the clouds that the vents generate.
