The Goshikinuma trail is one of Japan’s most photographed nature walks — a gentle, almost flat path linking a chain of vividly coloured ponds in the Urabandai highlands of Fukushima. It takes most people 1 to 1.5 hours to cover the roughly 4 km one way, and the total elevation change is negligible. If you’re expecting a mountain, recalibrate: this is a stroll, and it’s glorious precisely because of that.
What makes it special is the water. Each pond glows a different shade — emerald, cobalt, turquoise, rust-red — coloured by the minerals dissolved in it, and the hues shift with the season, the weather and the angle of the light. Add autumn foliage or fresh spring green, and you have one of the most rewarding easy walks in Japan. Here’s how to do it properly: the ponds, the access, the best timing, and the honest practicalities.

How the ponds were born
The ponds exist because of one of Japan’s most violent volcanic eruptions. In July 1888, Mount Bandai erupted catastrophically, collapsing the mountain’s northern face and damming the Nagase River with an enormous debris avalanche. The blocked river formed dozens of lakes and ponds across the Urabandai plateau — Goshikinuma, the “Five-Coloured Ponds,” are the most famous cluster. (You’ll occasionally see 1887 cited; the eruption was July 1888.)
The colours come from minerals — iron, aluminium and other compounds — dissolved in the water, each pond with its own chemistry and therefore its own hue. It’s geology you can see, and it changes: the same pond can look emerald in the morning and deep blue at noon.
Getting there
The rail gateway is Inawashiro Station on the JR Ban’etsu West Line, reachable from Koriyama (on the Tohoku Shinkansen) or from Aizu-Wakamatsu. From Inawashiro Station, take the bus bound for the Urabandai highlands and get off at Goshikinuma-iriguchi — the ride takes about 30 minutes and costs around ¥790. Buses run roughly every 1–2 hours, so check the timetable before you travel and plan your return in advance — missing the last bus back strands you in the highlands.
Most walkers start at the Bishamon-numa end (the Goshikinuma-iriguchi stop) and walk through to Yanagi-numa at the far end, from where buses connect back toward Inawashiro and the wider Urabandai area. Drivers have it easiest: there’s parking at both ends of the trail, and the highland roads are well maintained in season.
From Tokyo, the realistic routing is Shinkansen to Koriyama, local train to Inawashiro, then the bus — a half-day journey each way, which is why most people fold Goshikinuma into a wider Fukushima trip rather than attempting it as a Tokyo day trip.
The ponds, one by one
Walking from the Bishamon-numa end, the ponds unfold in sequence. Each has its own character:
- Bishamon-numa — the largest and most famous, with the classic postcard view: still water, forested slopes, and Mount Bandai rising behind. This is where the row boats are (around ¥700 for 30 minutes) — rowing out onto water that shifts from green to blue is worth every yen.
- Aka-numa (“Red Pond”) — smaller, with distinctive reddish tones from iron-rich water and red pondweed.
- Midoro-numa — a deep, saturated green, often called the most beautiful of the smaller ponds.
- Ryu-numa — compact and moody, tucked among the trees.
- Benten-numa — named for the goddess Benzaiten, with a small shrine nearby; the colours here run emerald to cobalt.
- Ruri-numa — “lapis lazuli pond,” and on a clear day the name needs no explanation.
- Ao-numa (“Blue Pond”) — an intense, almost unreal blue that stops first-timers mid-step.
- Yanagi-numa — the far end of the walk, fringed with willows, quieter than the Bishamon end.
The trail between them is a delight in itself: boardwalk sections, birch and beech forest, and viewpoints angled to catch each pond’s best face. It’s well signed in English and Japanese throughout.
Practical details
The trail is free and open to everyone — no permits, no gates, no entry fee. The path is wide, well-maintained and mostly flat, with boardwalks over the marshy sections. Ordinary walking shoes are fine; you don’t need hiking boots.
Toilets are available at both ends of the trail. There are shops and a small visitor centre near the Bishamon-numa entrance selling drinks, snacks and local souvenirs. The row boats on Bishamon-numa cost around ¥700 for 30 minutes and operate in the warmer months — check locally whether they’re running on your visit day, as they don’t operate in bad weather.
Because the walk is one-way between two bus stops, the logistics matter more than the walking: check the return bus times before you set off. Buses are infrequent (every 1–2 hours), and the far end of the trail is not where you want to be improvising transport.
Seasonal notes
- Spring (late April–May): fresh green foliage, snowmelt-fed ponds at their fullest, far fewer visitors than autumn. A lovely, quiet time.
- Summer (June–August): the highlands are deliciously cool when the cities swelter — Urabandai sits at altitude and makes a natural summer escape. Pond colours are vivid in strong sun.
- Autumn (October–early November): the famous season. The foliage peaks from late October into early November, and the combination of red and gold leaves with the coloured ponds is the Goshikinuma of the posters. It’s also the busiest time — go on a weekday if you can.
- Winter: the highlands get serious snow. The walking trail as such isn’t a winter proposition for casual visitors; check locally whether guided snowshoe walks are operating, as these run in some years.
One more timing note that matters more than the season: the pond colours are best in direct sun. An overcast day mutes every hue. If you have flexibility, pick the sunniest day of your trip for Goshikinuma — and walk in the morning, when the light angles into the ponds and the tour buses haven’t arrived.
What to bring
- Comfortable walking shoes — trail shoes or sturdy sneakers are plenty
- Camera — this is one of Japan’s most photogenic easy walks
- Sun protection — several pond viewpoints are fully exposed
- Drinks and a snack — shops exist at the Bishamon end, but not along the trail
- Cash (coins and small notes) — for the boats and the bus
- A printed or screenshotted bus timetable for your return
Where to stay
The Urabandai highlands have a good spread of onsen hotels and pensions — and after a day of pond-walking, a hot spring bath with a mountain view is the correct evening. Staying locally also lets you hit the trail early, before the day-trip buses arrive. Alternatives: Inawashiro town at the foot of the mountains, or Aizu-Wakamatsu — the castle town 30–40 minutes west — which pairs a samurai-history day with your nature day.
The natural companion trip is Mount Bandai itself — the volcano that created these ponds. Climbing Bandai one day and walking its flooded aftermath the next is one of Fukushima’s great two-day combinations, and it gives the ponds a backstory you’ll appreciate with every step.
Our tips
- Go on the sunniest day available. We’ve said it before because it’s the single biggest factor: sun transforms the ponds, cloud flattens them. Check the forecast and be flexible.
- Start early and walk Bishamon → Yanagi. Beginning at the Goshikinuma-iriguchi end puts the famous ponds first while the light is good and the crowds are thin, and the far end is quieter for the finish.
- Take the boat. Around ¥700 for 30 minutes on Bishamon-numa sounds like a tourist trap; it isn’t. The colour shifts you see from water level don’t happen from the shore.
- Photograph the reflections, not just the water. On calm mornings the ponds double the forest and sky — the reflection shots are the ones that stand out.
- Check the return bus before you start walking. With buses every 1–2 hours, a missed connection costs you an hour standing at a rural bus stop. Screenshot the timetable at the visitor centre.
- Pair it with Bandai. The ponds are beautiful on their own; they’re unforgettable when you’ve stood on the volcano that made them the day before. See our Mount Bandai hiking guide for the climb.
FAQs
Is the Goshikinuma trail a hike?
Honestly, no — and that’s its charm. It’s a flat, well-maintained 4 km nature walk taking 1 to 1.5 hours, suitable for children, older walkers and anyone who wants Japan’s scenery without Japan’s mountains. Come for the colours, not the workout.
How long does the walk take?
The walking itself is 1 to 1.5 hours one way. Most visitors spend 2 to 3 hours total once you add photo stops, the pond viewpoints and — recommended — a 30-minute row boat session on Bishamon-numa.
When were the Goshikinuma ponds formed?
In July 1888, when Mount Bandai erupted catastrophically and its debris avalanche dammed the Nagase River. Some older sources say 1887, but the eruption — one of Japan’s most destructive — was July 1888.
When is the best time to see the pond colours?
Two answers: the best season is autumn, with foliage peaking from late October to early November; the best weather is direct sunshine on any date, which makes the mineral colours glow. A sunny day in May beats a grey day in October.
How do I get to Goshikinuma without a car?
Take the JR Ban’etsu West Line to Inawashiro Station, then the bus to Goshikinuma-iriguchi — about 30 minutes and around ¥790. Buses run roughly every 1–2 hours, so check the timetable and plan your return journey before you start walking.
Can I combine Goshikinuma with Mount Bandai?
Absolutely — it’s the classic Fukushima pairing. Walk the ponds one day and climb the volcano that created them the next. Our Mount Bandai hiking guide covers routes, access and the 1888 eruption in detail.
The bottom line
Goshikinuma is proof that Japan’s outdoors aren’t only about summits. Four easy kilometres, eight coloured ponds, one catastrophic eruption behind it all — and an honesty worth repeating: go on a sunny day, start early, take the boat, and check the bus home before you set off. Do that, and the Five-Coloured Ponds will give you one of the prettiest half-days in the country.
