Killing riverbank (=Sesshōgawara)
"Killing riverbank" Located at the foot of Mt. Kusatsu-Shirane (active volcano) in Gunma prefecture. The area where gas containing hydrogen sulfide is ejected. It is forbidden to stop.
※The full hydrogen sulfide smoke hurt my lungs for two days. It's really dangerous.
