If you’re planning a scenic getaway in Takasaki City, Gunma Prefecture, Haruna‑ko Lake and Haruna Fuji Mountain offer a mix of nature, outdoor activities, and local culture all year long.

This guide brings you specific prices, transportation details, opening hours, and real practical tips so you can plan your trip with confidence and ease.

Where Are They & Why Visit?

Haruna‑ko Lake is a caldera lake formed by volcanic activity, set at about 1,084 meters above sea level with calm waters and mountain views that change with the seasons. Haruna Fuji is the smaller volcanic peak nearby with scenic outlooks and a ropeway for easy access to great viewpoints. Both destinations are ideal for nature lovers, photographers, and explorers looking for a relaxing yet active experience in the mountains of Gunma.

Best Time to Visit

- Spring & Summer (April–August): Perfect for walking around the lake, boat rides, cycling, and camping. The weather is comfortable for outdoor activities. Boating and rentals usually operate from morning until late afternoon.

- Autumn (Late October–Early November): The autumn foliage season is especially popular — deep reds and golds frame the lake and mountain scenery in a breathtaking display.

- Winter (December–February): The lake may freeze, and ice fishing becomes an option when conditions allow. Winter scenery also has a peaceful, snowy charm.
