Unveiling Urabandai’s Hidden Gem
Hello, fellow Japan adventurers! Japanist here, ready to whisk you away to another one of Japan’s best-kept secrets. When most people envision Japan, images of bustling Tokyo streets, ancient Kyoto temples, or perhaps the serene beauty of cherry blossoms often come to mind. And while those iconic sights are undeniably magnificent, Japan is also a land of breathtaking natural wonders, often tucked away in less-trodden paths, waiting to be discovered by those with a keen eye for authentic beauty. Today, we’re setting our sights on such a place: Urabandai, a truly enchanting region nestled in the heart of Fukushima Prefecture. Specifically, we’re diving deep into the mystical allure of its crown jewel, the Goshikinuma Lakes, or as they are affectionately known, the “Five-Color Ponds.”
Urabandai, translating to “behind Bandai,” refers to the northern side of Mount Bandai, a majestic stratovolcano whose powerful eruption in 1888 dramatically reshaped the landscape, giving birth to a unique terrain dotted with numerous lakes and ponds. This cataclysmic event, while devastating at the time, ironically created an ecological masterpiece, a vibrant tapestry of nature that continues to evolve. The Goshikinuma Lakes are a direct result of this geological upheaval, a series of ponds formed by the debris flows that blocked rivers. What makes them truly special, and frankly, almost magical, is their astonishing ability to display an array of vivid colors, shifting from emerald green to cobalt blue, and even a mystical reddish-brown, depending on the season, weather, and the angle of the sun.
For those of you seeking an escape from the urban sprawl and a profound connection with nature, Urabandai offers an unparalleled experience. It’s a destination that promises tranquility, stunning vistas, and a chance to witness one of nature’s most captivating art installations. Unlike some of Japan’s more famous natural parks, Urabandai retains an air of serene solitude, making it a perfect spot for those who prefer to explore at their own pace, away from the crowds. While it gains significant popularity during the autumn foliage season, its charm extends throughout the year, each season painting the landscape with a different, equally mesmerizing palette. As you plan your visit, remember that this is a natural environment. Comfortable footwear is a must, and an open heart ready to embrace the wonders of the wild will enhance your journey infinitely. Prepare to be captivated by the ever-changing hues of Urabandai’s Goshikinuma, a secret worth sharing.
A Kaleidoscope of Nature: Exploring Goshikinuma
Now that we’ve set the stage, let’s embark on a detailed exploration of what makes the Goshikinuma Lakes truly extraordinary. The name “Goshikinuma” literally means “Five-Color Ponds,” but this moniker barely scratches the surface of the chromatic diversity you’ll encounter. Formed by the collapse of Mount Bandai’s peak during the 1888 eruption, which created a natural dam, these ponds are characterized by unique mineral compositions from the volcanic ash and underground spring water, along with varying depths and concentrations of algae, all contributing to their miraculous color shifts. Walking the Goshikinuma Nature Trail, a well-maintained path stretching approximately 4 kilometers (2.5 miles), allows you to witness this phenomenon firsthand. It’s an easy to moderate hike, typically taking about 1 to 1.5 hours one way, and offers breathtaking views at every turn.
Let’s delve into some of the most prominent ponds along the trail, each with its own distinct personality:
First up, and often the starting point for many, is Bishamon-numa (毘沙門沼). This is the largest and arguably the most famous of the Goshikinuma ponds. Its expansive surface often shimmers with an emerald green or deep blue hue, depending on the light. What makes Bishamon-numa particularly captivating are the giant, multi-colored koi fish that swim gracefully in its waters. You can rent a rowing boat here and glide across the tranquil surface, getting an up-close perspective of the vibrant waters and the impressive koi. The backdrop of Mount Bandai rising majestically behind the pond adds to its picturesque charm, making it a favorite spot for photographers. Sometimes, you might even spot the elusive “heart-shaped koi,” considered a good luck charm by locals!
As you continue along the trail, you’ll encounter Aka-numa (赤沼), or the “Red Pond.” True to its name, this pond often exhibits a reddish-brown tint. This striking color is largely due to the high concentration of iron oxide in the water, which has rusted over time, staining the rocks and vegetation along its banks. It’s a fascinating example of how geology and chemistry combine to create unique natural phenomena.
Next is Midoronuma (みどろ沼), a pond that lives up to its name “muddy pond” but in the most beautiful way possible. Midoronuma is renowned for its fascinating characteristic: it displays multiple distinct colors within the same pond. Depending on where you look, you might see shades of green, blue, and even a faint yellow-brown, all separated by subtle underwater variations in mineral content and light reflection. It’s a natural canvas, ever-changing and endlessly intriguing.
Further along, you’ll reach Tatsu-numa (竜沼), or the “Dragon Pond.” This pond is often characterized by its deep, clear blue water. While not as dramatically varied in color as some of its counterparts, its serene beauty is undeniable. Local legend suggests a dragon resides beneath its surface, hence the name. From certain angles, the pond is said to resemble a heart, adding a romantic touch to its allure. The submerged aquatic plants in Tatsu-numa also contribute to its unique underwater scenery.
One of the most frequently photographed and breathtaking ponds is Benten-numa (弁天沼). This pond offers an astonishing array of blues, from a brilliant cobalt to a soft turquoise, and even a vibrant emerald green. Its color is particularly sensitive to light and the mineral content, allowing for stunning transformations throughout the day. A small island within Benten-numa, adorned with a miniature shrine, adds a mystical element to its already captivating beauty. The clarity of its water allows for glimpses of the submerged trees, creating an ethereal underwater forest effect.
Following Benten-numa, you’ll come across Ruri-numa (瑠璃沼), named after the lapis lazuli gemstone, renowned for its deep blue color. Ruri-numa lives up to its name, often showcasing a stunning, almost unnatural shade of deep blue, sometimes verging on purple. Its intense hue is mesmerizing and stands out even among the other colorful ponds.
Finally, towards the end of the trail, you’ll encounter Ao-numa (青沼), the “Blue Pond,” which, true to its name, consistently displays a vivid blue color. This pond is smaller but incredibly vibrant, and its intense blue is often one of the highlights for visitors. The surrounding greenery provides a stark contrast, making the blue pop even more.
The final pond on the main trail is Yanagi-numa (柳沼), the “Willow Pond.” This pond is typically the most tranquil and offers a peaceful conclusion to the Goshikinuma experience. It’s surrounded by willow trees and often reflects the sky, creating a calm, reflective surface.
The primary reason for the Goshikinuma Lakes’ extraordinary color variations lies in the unique combination of volcanic minerals, particularly aluminum and iron oxides, suspended in the water, along with the presence of various types of algae and microorganisms. These elements interact with sunlight, scattering and absorbing different wavelengths of light, resulting in the brilliant spectrum of colors. Furthermore, the depth of each pond, the amount of dissolved volcanic matter, and even the pH levels contribute to the distinct hues. This ever-shifting palette means that no two visits are exactly alike; the ponds are a living, breathing work of art.
The Goshikinuma Nature Trail itself is an experience. It’s mostly flat and well-maintained, suitable for most fitness levels, though proper trekking shoes are always recommended as the path can be uneven or slippery in places, especially after rain. Along the way, you’ll find informative signs (often in English) explaining the geology and ecology of the area. It’s important to remember that this is a natural habitat, so please stay on marked trails and avoid disturbing the environment. While rare, it is always advisable to carry a bear bell, as Urabandai is home to various wildlife.
The beauty of Urabandai and Goshikinuma truly transforms with the seasons.
In spring, the fresh green sprouts against the backdrop of lingering snow on Mount Bandai create a vibrant contrast, and the clear air enhances the ponds’ colors.
Summer offers a cool refuge, with lush greenery surrounding the ponds, perfect for escaping the urban heat. The deep greens and blues of the ponds are particularly striking under the summer sun.
Autumn is arguably the most popular season, as the entire landscape bursts into a fiery display of red, orange, and gold. The vibrant fall foliage reflected in the multi-colored ponds is an unforgettable sight, attracting photographers and nature lovers alike. Be prepared for larger crowds during this time.
However, for a truly magical and serene experience, consider visiting in winter. While some sections of the trail may be closed or require snowshoes, the sight of the ponds, often partially frozen and surrounded by pristine white snow, against the backdrop of a snow-capped Mount Bandai, is absolutely breathtaking and offers a unique, serene beauty rarely seen by most tourists. Snowshoe tours are available for deeper exploration.
Beyond the Goshikinuma Lakes, Urabandai offers other attractions. The Urabandai Visitor Center provides excellent information about the area’s geology, flora, and fauna. Nearby, Lake Hibara (桧原湖), the largest of the lakes formed by the 1888 eruption, offers boating, fishing, and cycling opportunities. Its numerous islands and inlets make it a scenic spot for leisurely cruises. The entire Urabandai Plateau is a haven for outdoor activities, from hiking and cycling in warmer months to skiing and snowboarding in winter.
Regarding access, Urabandai is surprisingly accessible despite its somewhat remote feel. The most common route is to take the Tohoku Shinkansen to Koriyama Station, then transfer to the local Ban’etsu West Line to Inawashiro Station. From Inawashiro Station, regular buses (Bandai Toto Bus) run directly to the Urabandai area, including the Goshikinuma Iriguchi (entrance) bus stop. For those who prefer flexibility, renting a car from Koriyama Station or even closer, from Inawashiro Station, is highly recommended. This allows you to explore at your leisure and reach more secluded spots. The drive through the mountainous landscape is scenic and enjoyable.

Japanist’s Nugget of Wisdom: Did You Know?
Japan, a country often celebrated for its ancient traditions and cutting-edge technology, is also a land shaped by the immense power of its geological activity. The very existence of Urabandai’s Goshikinuma Lakes is a magnificent example of this.
Did you know that Japan is part of the “Pacific Ring of Fire,” a horseshoe-shaped basin that is home to 75% of the world’s active and dormant volcanoes? This extensive geological feature accounts for Japan’s frequent seismic activity and its abundance of volcanoes and hot springs (onsen). Mount Bandai, the volcano responsible for the creation of the Goshikinuma Lakes, is an active stratovolcano, though its last major eruption was in 1888. The 1888 eruption was not a typical lava flow but rather a phreatic eruption, caused by superheated steam from groundwater interacting with magma, leading to a massive landslide that dammed rivers and created numerous lakes and ponds, including the Goshikinuma.
Furthermore, the unique color phenomenon of the Goshikinuma Lakes is directly linked to the specific mineral composition resulting from this volcanic activity. The water contains high levels of dissolved aluminum, iron, and other volcanic minerals. When light penetrates the water, these microscopic particles scatter certain wavelengths more than others. For example, particles of aluminum hydroxide tend to scatter blue light, making the water appear blue, much like the sky. Iron oxide particles, on the other hand, can contribute to reddish or brownish hues. The varying concentrations of these minerals, along with the presence of different types of microscopic algae and bacteria that thrive in specific chemical environments, lead to the diverse and ever-changing palette observed in the ponds. This is a scientific marvel, where geology, chemistry, and biology conspire to paint a natural masterpiece.
In some ways, the Goshikinuma Lakes are a microcosm of Japan’s geological story, showcasing how destructive forces can ultimately lead to creation and breathtaking beauty. It reminds us that even catastrophic events can pave the way for new forms of life and awe-inspiring natural wonders, forever altering landscapes and inspiring generations. It’s a powerful reminder of nature’s relentless cycle of destruction and renewal.
