โ™จ๏ธ Gunma|May 11, 2026

Volcanic Crater Lake of Haruna

Lake Haruna is a volcanic crater lake in the caldera of Mt. Haruna, spreading at about 1,100m elevation. Hot springs also emerge near the lake, making it a long-cherished resort and summer retreat.

The Spectacular Haruna Fuji

Haruna Fuji (1,391m) rising near the center of the lake is the symbol of Lake Haruna. The reflection of inverted Haruna Fuji on the lake surface is especially beautiful, with mystical morning mist creating a fantastical scene.

Year-Round Enjoyment

Summer offers pedal boats and cycling, winter brings smelt ice fishing and skating. Autumn foliage season spreads breathtaking scenery of the lake and autumn colors, attracting many visitors.
