Goshikinuma Lake, often referred to as the 'Five-Colored Ponds,' is not a single lake but a series of volcanic lakes and marshes formed after the 1888 eruption of Mount Bandai. Located in the Bandai-Asahi National Park, these ponds are renowned for their distinct and often changing colors, which are a result of volcanic minerals dissolved in the water and the varying light conditions. It's a significant natural landmark, offering a unique geological spectacle and a serene natural escape.
Visitors consistently praise the stunning beauty and vibrant colors of the lakes, with many describing the water as incredibly clear and the surrounding autumn foliage as breathtaking. The main Goshikinuma Walk, a 3.6 km trail, is frequently highlighted as easy and well-maintained, suitable for most fitness levels. Reviewers often mention the peaceful atmosphere and the opportunity to rent rowboats on Bishamon-numa, the largest pond, for a closer experience. Many find the experience enchanting, especially on clear days when the colors are most vivid. Some visitors note that the actual number of distinct colors might be closer to three rather than five, with some ponds appearing similar.
For the best experience, visitors recommend going early in the morning to avoid crowds and enjoy the tranquility. The autumn season is particularly popular for its vibrant fall colors, though the lakes are beautiful year-round, even in winter with snow. Wear comfortable walking shoes, as the trail can be muddy after rain. While the path is generally flat, some sections might be uneven. Allow approximately 1.5 to 2 hours to complete the main walk at a leisurely pace. Bringing water and snacks is advisable, as facilities along the trail are limited. Some visitors suggest that the colors are most impressive on sunny days, so checking the weather forecast is recommended.
To reach Goshikinuma, many visitors travel by car, as parking is available at both ends of the trail (near the Visitor Center and the Urabandai Products Center). For those using public transport, take a train to Inawashiro Station, then transfer to a local bus that goes to the Goshikinuma area. Reviewers mention that the bus ride is straightforward, and the starting point of the trail is easily accessible from the bus stop. In winter, visitors recommend hiring boots from the visitor's center for walking in the snow, with a refundable deposit.
A common complaint among some visitors is that the colors of the ponds might not always live up to the 'five-colored' expectation, especially on cloudy days or if they visit during seasons when the colors are less pronounced. To mitigate this, consider visiting on a clear, sunny day, and manage expectations regarding the exact number of distinct hues. While the 'red pond' (Aka-numa) might appear green to some, the overall beauty of the landscape and the easy walk are still highly regarded.
