Located in Hokkaido, Noboribetsu is home of the famous Jigokudani or “Hell Valley,” a volcanic crater said to resemble hell on earth. But it’s just as scenic as it is hellish, and after you’ve enjoyed a hike during summer, the fiery devils appear at night for the Demon Fireworks of Noboribetsu.

With swirling steam wafting upwards to the heaves, one wouldn’t be surprised to find a few demons hiding in the rugged terrain or enjoying the naturally occurring hot springs and footbaths.

The fireworks displays are free to watch typically in June and July, and start at 8:30 p.m., with a run time of about 30 minutes. To get a seat on the raised viewing steps for the fireworks, arrive about 8 p.m. However, note that those wearing open-toed shoes will not be allowed in this section.
