Goshikunuma

Goshikinuma refers to a group of lakes located in the Urabandai area of northern Fukushima Prefecture, officially known as the "Goshikinuma Lake Group." In 1888, a steam explosion occurred in the area, including the small Bandai to the north of Mount Bandai, resulting in landslides that blocked rivers and formed approximately 300 lakes in the region. In 2016, it was awarded one star in the Michelin Green Guide and has since attracted attention from both domestic and international visitors.

Origin of the Name and Color Changes
"Goshiki" does not mean five lakes; rather, it refers to the diverse colors found in each lake. The lake surfaces display a range of hues including emerald green, cobalt blue, turquoise blue, emerald blue, and pastel blue, which can change based on weather, seasons, time of day, viewing angles, the presence of volcanic materials and mineral particles in the water, acidity, and water depth. This variability is a major attraction, allowing visitors to experience different appearances on each visit.

Main Lakes and Highlights
Bishamon-numa: This is the largest lake in Goshikinuma and offers rowboat rentals (typically open from April to November, closed in winter). Many carp swim here, and encountering a red-heart-patterned carp is considered a sign of good luck.
Aonuma: Known for its vivid and clear blue color, it symbolizes the "mystical lake" experience.
Akanuma: This lake's unique scenery allows one to see the surrounding vegetation tinged red due to iron content in the water.
Midoronuma: A distinctive lake said to appear in three colors depending on the angle of view and light conditions.
Yanagikuwa: This lake boasts high transparency and a clear, beautiful water color.

Goshikinuma Nature Trail
The "Goshikinuma Nature Trail," connecting the lakes, is approximately 3.6 km long, with a walking time of about 1 hour and 30 minutes, suitable for beginners (some guides may indicate a one-way distance of about 4 km and a time of 1 hour and 20 minutes to 2 hours). There are entrances, parking areas, and bus stops on the east side (Goshikinuma Entrance/Bishamon-numa side) and west side (Urabandai Kogen Station/Yanagikuwa side), making it common and convenient to take a bus to the opposite side first and then walk one way. The trail is gentle but can be slippery after rain, so wearing non-slip trekking shoes is recommended. Along the way, there are viewing points where you can admire the colors of the lakes as well as the majestic sight of Mount Bandai, one of Japan’s 100 famous mountains.

Seasonal Attractions
From spring to summer, the colors of the lake surfaces contrast beautifully with new and deep green foliage, while in autumn, the fall foliage typically reaches its peak from mid-October to early November. In winter, visitors can enjoy snowshoeing and the enchanting sight of the snow-covered lakes. During the snow season, the summer paths are hidden, so it is advisable to have a local guide for safety against getting lost or slipping.

Pets and Safety Etiquette
Pets are allowed on the nature trail, but they must be on a leash, and all waste must be taken home. Be cautious of wildlife such as bears and monkeys in the area. As this is a special protected area within a national park, please refrain from collecting plants, animals, or stones, and avoid going off the designated paths.

Access Tips
By car, take the Ban'etsu Expressway from the Inawashiro Bandai Kogen IC towards Urabandai for about 20 minutes. If using public transport, take a bus from JR Inawashiro Station and get off at "Goshikinuma Entrance" or "Urabandai Kogen Station." The boat services at Bishamon-numa are weather-dependent, so it’s a good idea to check for the latest information before your visit.

Caution Against Confusion
Please note that the crater lake "Goshikinuma" (also known as "Witch's Eye") seen from the Jododaira side and Mount Issaikyo is a different location from the Goshikinuma Lake Group in Urabandai. Make sure to confirm your destination when planning your trip.
