I went to Hell! It was really creepy and smelled like sulfur.
I took pictures!
Well, a picture…
I had more/better pictures but I don’t know what happened to them.
Anyways, this is a region in 雲仙（うん・ぜん）known as 地獄（じ・ごく）, or Hell.
It is very hot, and you can hear the sound of water boiling constantly. Hot spring stuff, you know.
It was especially creepy since I went there past midnight with a bunch of 怖がり.
If you want more info about the place, you can check out the official site for the area.(日本語）
