Goshikinuma Ponds Overview
Nestled at the foot of Mt. Bandai in the Urabandai area of Fukushima prefecture, the Goshikinuma Ponds are one of Japan’s most mesmerizing natural wonders. The name translates to “Five Colored Ponds,” though the area actually consists of roughly 30 lakes and marshes — each displaying its own vivid hue thanks to the volcanic minerals deposited by Mt. Bandai’s catastrophic eruption on July 15, 1888.
That eruption, a massive steam explosion, destroyed nearby villages and dramatically reshaped the landscape, damming rivers and creating the highland lake district that exists today. The minerals and varying pH levels in each body of water produce an extraordinary spectrum of colors, from reddish green to cobalt blue, that shift with the seasons, weather and time of day. Notable ponds include Bishamon, Aka, Midoro, Tatsu, Benten and Ao, with Ao-numa in particular famous for its otherworldly turquoise color.
A well-maintained 3.6-kilometer nature trail connects the ponds, running from Bishamon-numa — the largest, where visitors can rent rowboats — to Lake Hibara, and takes about 70 to 90 minutes to walk at a leisurely pace. The trail is beginner-friendly and largely flat, making it ideal for families and casual hikers. In winter, snowshoe trekking tours are available, and the lakes look especially vivid against the white snow, as the mineral content prevents some of them from freezing over.
Best Times To Visit Goshikinuma Ponds
Goshikinuma is accessible year-round, with each season offering a distinct experience. Autumn is the most popular time to visit, with peak foliage typically falling between mid-October and early November, when the fiery reds and golds of the surrounding forest contrast beautifully with the colorful waters. Late spring through summer (May to August) brings lush greenery and comfortable hiking weather, while winter draws visitors seeking serene snowscapes and snowshoe tours. As the ponds’ colors change depending on the light, weather and season, repeat visits are rewarded with entirely different views.
