Onuma Lake, atop Mt. Akagi, is full of small fish called wakasagi, or Japanese pond smelt. When the lake freezes over in the winter, you can go ice fishing for wakasagi. Drill a hole in the ice, drop in your line, and see if you can lure in some of these small, tasty fish!
Beginners welcome!
Several shops around the lakeshore rent and sell ice-fishing equipment. If you let the shop owner know it’s your first time, they’ll show you how to fish and use the equipment. They’ll also deep-fry the fish you catch free of charge!
Just the view from the ice itself is also beautiful.
CAUTION: The Akagi summit is about 10° - 15°C colder than ground level. Please dress accordingly!
Open season: Mid-January to the end of March (varies by year depending on ice conditions)
Ice hours: 7:00 AM – 2:00 PM daily
2024 season: Open since Wednesday, Jan. 31th
At present, the only entrances to the ice will be:↓
1. The Daidō（大洞）entrances near the shopping street on the southeast bank of the lake
2. The Noshiri/Numajiri（沼尻）entrances near Aoki Ryokan.
