Mount Akagi: Highland and Lakes Formed by a Volcano

Gunma's Symbol Mt. Akagi

Mt. Akagi is a stratovolcano cherished as Gunma's symbol, with multiple peaks centered on the highest peak Kurobi Mountain (1,828m). The summit area has crater lakes Onuma and Konuma, creating a unique highland landscape.

Recreation at Onuma Lake

Onuma Lake freezes completely in winter, becoming a famous smelt fishing spot. Ice fishing for smelt is a popular winter tradition. Summer offers boating and canoeing on the lake.

Scenic Beauty Through the Seasons

Spring brings rhododendron blooms coloring the mountain, autumn features beautiful foliage, and winter spreads a snowy landscape. The scenery of Akagi Shrine's vermilion buildings with the lake is especially beautiful, attracting many photographers.
