Mt. Akagi Summer Festival

Spend the day lakeside at Lake Onuma, a caldera lake on Mt. Akagi, to celebrate the Mt. Akagi Summer Festival. This vibrant festival encourages visitors to participate in various activities, including traditional archery, tree-climbing, and slack-lining. Don't miss watching the rowing boat rally and seeing the various performances at Mt. Akagi-jinja Shrine.

The air is filled with jazz as bands play on an open-air stage throughout the day.

Twilight hiking sometimes an option and requires bookings. Spend the evening watching fireworks while floating paper lanterns are released onto the lake.
