Drive along National Route 252 from Tadami towards the Niigata border, and round a bend in the mountain road a huge concrete wall suddenly appears before you, with an expanse of lake stretching endlessly behind it.
This is Lake Tagokura in Tadami, Minamiaizu District, Fukushima Prefecture, formed where Tagokura Dam holds back the Tadami River, and in autumn the forested mountains around its shores turn red, orange and yellow layer by layer.
Lake Tagokura lies in one of the heaviest snowfall areas in Japan, so the autumn leaves come earlier than around Tadami Station further down, winter also arrives early, and the window for autumn-leaf viewing is shorter than at most spots.
The questions people ask most when planning are: when are the autumn leaves at Lake Tagokura at their best? When does the national route close? And if you come on the Tadami Line, how do you get up to the dam from the station?
This article draws on information published by the Tadami Information Center, Fukushima Prefecture, Electric Power Development (J-POWER) and the Japan Weather Association’s tenki.jp to explain the autumn-leaf season, the viewpoints, road closures, access and itineraries all in one place.
If you are planning an autumn trip around Aizu, the Tadami Line or the Uonuma area of Niigata, by the end you will know how to fit Lake Tagokura in.
Where Is Lake Tagokura? A Huge Dam Lake on the Fukushima–Niigata Border
Lake Tagokura lies on the western side of Tadami in Minamiaizu District, Fukushima Prefecture, right next to the Niigata border, and is an artificial lake on the upper Tadami River.
The Tadami Information Center’s introduction to Tagokura Dam and Lake Tagokura explains that the lake was formed by Tagokura Dam holding back the Tadami River, and that its storage capacity ranks among the largest in Japan.
Some parts of the shore can only be reached by boat, and there are even areas no one has set foot in, which is why locals often describe it as a “hidden wilderness”.
Tagokura Dam and Power Station
Tagokura Dam and its power station are managed by Electric Power Development (J-POWER) and are power facilities on the Tadami River in the Agano River system.
J-POWER’s list of hydroelectric power stations lists Tagokura Power Station as a dam-type power station with a maximum output of 400,000 kW, which began operating in 1959.
Standing on the dam and looking downstream, you can see the power station, the substation equipment and the winding Tadami River, in striking contrast with the broad expanse of lake on the upstream side.
The Village of Tagokura, Submerged by the Lake
The bed of Lake Tagokura was once a mountain village called Tagokura, and the whole settlement was submerged after the dam was built.
Tadami’s “Furusatokan Tagokura” is a museum set up to preserve this memory; it was originally run as a private museum by Mr Minagawa, who came from the village of Tagokura, and was later taken over by the town.
Seeing the lake and then visiting the museum will change how you feel about the water in front of you.
Furusatokan Tagokura is in central Tadami and is open 9:00–17:00 (last entry 16:00); it is closed on Tuesdays (or the next weekday if Tuesday is a public holiday) and over the New Year holidays.
Admission is 310 yen for high school students and above, 210 yen for primary and junior high school students and free for pre-school children, and the ticket is shared with the “Tadami Beech and River Museum” (as of October 2026).
If it rains or is too cold, adding the museum and the river museum to your itinerary is a good fallback for getting to know Tadami’s nature and history.
Tadami, a Town of Heavy Snow and Beech Forest
The Ministry of Land, Infrastructure, Transport and Tourism’s “100 Best Water Villages” profile of Tadami notes that cumulative annual snowfall of more than 20 metres is not unusual here, and the abundant snowmelt is the source of the power generation.
Forest covers about 94% of the town’s area, and its deciduous broadleaf forest, mainly of beech, is considered first-rate in Japan for both scale and naturalness.
The area around Lake Tagokura belongs to the Echigo Sanzan-Tadami Quasi-National Park, and what turns red in autumn is this forest of interwoven beech, oak and maple.
When Are the Autumn Leaves at Lake Tagokura at Their Best? Timing Your Visit in 2026
The Japan Weather Association’s tenki.jp Tagokura Dam autumn-leaf page gives the usual peak as mid-October to early November, with the main trees being beech, oak and maple.
The Tadami Information Center’s FAQ also says that the autumn-leaf season in Tadami usually runs from mid-October to early November.
tenki.jp also specifically notes that the leaves at Tagokura change colour earlier than around Tadami Station, and the first snow also comes early, falling as early as the end of October in some years.
Taken together, the autumn-leaf window at Lake Tagokura runs roughly from mid-October to early November, and the time we recommend most is late October.
The Japan Weather Association’s Forecast for 2026
In its 2026 autumn-leaf peak forecast, the Japan Weather Association states that this year the peak across Japan will generally be around the usual time or later than usual.
The forecast says most spots in northern Japan will be roughly on a par with a usual year, but some places in southern Tohoku may be later than usual.
tenki.jp’s 2026 peak forecast for Tagokura Dam is likewise mid-October to early November, the same as a usual year.
The Japan Weather Association plans to update its forecast on tenki.jp three or four times in total up to November, so the safest approach is to check the status on tenki.jp again a week before you set off.
Why Do We Recommend Late October Most?
The first reason is the autumn leaves themselves: the Tagokura area is relatively high, and late October is usually when the colours on the mountains around the lake are most complete.
The second reason is the road: the Niigata border side of National Route 252 closes for the winter from 4 November 2026, so anyone coming from the Niigata direction has to go by 3 November.
The third reason is facilities: Lake View Tagokura beside the dam ends its season on 8 November 2026, and from early November onwards there are fewer places to rest and use the toilet.
What Will You See at Different Times?
In mid-October the higher ridges change colour first while the shores of the lake are mostly still green, in early-autumn tones.
Late October is usually when the colours are fullest overall, with the lake reflecting mountains in a mix of red, orange and yellow.
From early November the leaves start to fall and you may also meet the first snow; with luck you may see autumn leaves and white snow in the same view, but the road and weather risks rise too.
How Do the Lake and Forest Colours Look?
The autumn leaves at Lake Tagokura are mainly beech, oak and maple, so the overall tone leans towards yellow and orange, with the maples adding touches of red.
On sunny days the lake is a deep blue-green, contrasting with the warm colours on the slopes, which is when it is most photogenic.
On cloudy days the colour of the lake becomes more subdued and mist drifts through the valleys, giving it even more of a deep-mountain-lake atmosphere.
Must-See Autumn-Leaf Spots: The Dam, Lake View and Rokujuri-goe
Lake Tagokura is large, but the viewpoints most visitors can reach easily are mainly around the dam and along National Route 252.
The Top of Tagokura Dam and Lake View Tagokura
Lake View Tagokura (formerly Tagokura Lake View) beside the dam is a tourist rest facility selling Tadami produce and souvenirs, and it also serves light meals such as coffee, soft-serve ice cream, hot dogs, fried rice and pizza.
There are two toilets next to the car park, making it the most important rest stop in the area.
From the dam you can look at Lake Tagokura and its autumn leaves upstream while gazing downstream towards Tadami, and the views on either side are completely different.
Rokujuri-goe Pass Road-Opening Monument: A Viewpoint Overlooking Lake Tagokura
The Rokujuri-goe Pass Road-Opening Monument is said to have the best view on the Yukiwari Kaido, and from this viewpoint at 750 metres you can look down over Lake Tagokura.
The car park beside the monument holds only about 4 cars, and large coaches have to use the large car park about a 10-minute walk away in the Niigata direction.
Tadami’s suggested itinerary is to drive a further 20 minutes or so from Lake View to the monument, about 40 minutes there and back.
Note that the monument is on the Niigata border section of National Route 252 that closes from 4 November, so in 2026 plan to go by 3 November.
Along the Yukiwari Kaido on National Route 252
National Route 252 runs along the north shore of Lake Tagokura and is known locally as the “Rokujuri-goe Yukiwari Kaido”, with quite a few places along the way where you can see the lake.
This stretch has many bends, tunnels and snow sheds and little room at the roadside, so please stop for photos only where there is a parking space.
When driving through, also watch out for oncoming traffic and falling rocks; autumn evenings get dark quickly, so we do not recommend being on the mountain road too late.
2026 Road Closures and Facility Opening Periods
The seasonal limits at Lake Tagokura come mainly from the winter closure of National Route 252 and the opening period of Lake View Tagokura, and you should check both in advance.
Winter Closure of National Route 252
In a release dated 6 October 2026, Fukushima Prefecture’s Minamiaizu Construction Office announced that National Route 252 will close for the winter from 9:00 on 4 November 2026.
The closed section runs from Kimenzan, Tagokura, Tadami (the Niigata border) to Ushiroyama, Tagokura (the Tagokura free rest area), about 7.38 km long.
Deai Bridge on this stretch was once swept away by an avalanche and traffic currently uses a temporary bridge, which is removed before the snow season to prevent winter avalanches from washing it away again.
The same release also explains that the section from the Tagokura free rest area to Kaminomiyabuchi, Ishibushi, Tadami is scheduled to close around late November, as in previous years.
In other words, from 4 November you can only reach the dam area from the Tadami side, and you cannot cross Rokujuri-goe from the Uonuma direction in Niigata.
Lake View Tagokura Opening Period
A notice from the Tadami Information Center announces that Lake View Tagokura is open in 2026 from late April to 8 November, from 9:30 to 16:00.
The Lake View Tagokura introduction page, however, says it opens on Saturdays, Sundays and public holidays, so check with the Tadami Information Center in advance whether it is open on weekdays.
It closes for the winter every year from mid-November to late April the following year, so take particular care if you are going in the second half of the autumn-leaf season.

Getting to Lake Tagokura: Train, Taxi and Car
There is no direct local bus to the Lake Tagokura area, so most visitors drive, or take the JR Tadami Line to Tadami Station and change to a taxi.
By JR Tadami Line to Tadami Station
Tadami’s access information lists two rail routes: from Koriyama Station on the Tohoku Shinkansen, change to the Ban-etsu West Line to Aizu-Wakamatsu and then take the Tadami Line to Tadami; or from Urasa Station on the Joetsu Shinkansen go to Koide and take the Tadami Line towards Tadami.
There are very few Tadami Line trains a day, so check your outward and return trains on the JR East timetable first and then plan how long to stay in Tadami.
There used to be a Tagokura Station on the Tadami Line, but it has closed, and the nearest station to Lake Tagokura is now Tadami Station.
From Tadami Station to the Dam: Taxi and Bicycle
Tadami’s suggested itinerary says the drive from Tadami Station to Lake View takes about 10 minutes.
If you want to take a taxi from Tadami Station, the Tadami Information Center recommends booking in advance; the local taxi companies are Tadami Kanko Taxi and Asahi Taxi.
You can also rent a bicycle to ride up, but the way to Lake Tagokura is uphill all the way and hard going on an ordinary bicycle, so locals recommend renting an electric-assist bicycle, and you need to take extra care on the many bends.
By Scheduled Shuttle Van from Aizu-Tajima
If you are coming from Asakusa in Tokyo on the Tobu and Aizu Railway lines, you can go to Aizu-Tajima Station and change to the “Aizu-Tajima–Tadami Scheduled Shuttle Van (Shizen Shuto Tadami-go)” to Tadami Station.
Groups of 5 or more must book in advance with the Tadami Chamber of Commerce and Industry, and once at Tadami Station you still need to change to a taxi or rental car to go up to Tagokura.
By Car
Tadami’s access information says the drive from Sendai to Tadami takes about 3.5 hours, either via Aizu-Wakamatsu IC on the Ban-etsu Expressway and National Routes 121 and 289, or from Aizubange IC along National Route 252.
From Tokyo it takes about 4 hours via Shirakawa IC or Nishinasuno-Shiobara IC on the Tohoku Expressway; from Niigata it takes about 2.5 hours via Koide IC on the Kan-etsu Expressway and National Route 252.
The route from Koide IC over Rokujuri-goe can only be used until 3 November in 2026; from 4 November, please take the roads on the Fukushima side instead.
There are free car parks in front of Tadami Station and next to Tadami Line Plaza, where those arriving on the Tadami Line can also meet a rental car or transfer.
Tips on the First Snow and Mountain Driving
tenki.jp notes that in years when it comes early, the first snow falls at Tagokura at the end of October, so if you are going up from late October onwards, check the weather forecast and road conditions first.
If you are driving a rental car, it is best to confirm the tyre type when booking for the second half of the autumn-leaf season, and if the road is icy or snow-covered, anyone unfamiliar with driving on snow should not push on up the mountain.
There are very few shops along National Route 252, so fill up with fuel and buy drinks in Aizu or central Tadami before you set off for peace of mind.
Suggested Time and Itineraries
You can see the main views at Lake Tagokura itself in about an hour; what matters is how you link it with the Tadami Line, hot springs or nearby sights.
| Itinerary type | Suggested time | What to do |
|---|---|---|
| Dam area | About 1 hour | Top of the dam, rest and a bite to eat at Lake View Tagokura |
| Lakeside drive | About 2 hours | The dam, the Yukiwari Kaido and the Rokujuri-goe Pass Road-Opening Monument (by 3 November) |
| Lake and hot spring | About half a day | Lake Tagokura and a day-trip bath at Fukasawa Onsen |
| Tadami Line combination | About a full day | Tadami Line views, Tadami, Lake Tagokura and the First Tadami River Bridge |
Itinerary 1: Lake Tagokura and a Hot-Spring Tour
The “Lake Tagokura and Hot-Spring Tour” recommended by Tadami involves driving from Tadami Station to Lake View, seeing the lake and then bathing at Fukasawa Onsen, taking about 2 hours or more in all.
Fukasawa Onsen has two day-trip baths: “Toki no Sato Yurari” is open 11:00–20:00 and costs 700 yen for adults and 250 yen for primary school children, with a restaurant and an open-air bath.
“Murayu”, with free-flowing spring water, is open 9:00–20:30 and costs 600 yen for adults and 200 yen for primary school children, with light meals such as ramen (all as of October 2026).
Itinerary 2: An Autumn Day Trip Along the Tadami Line
Setting out from the Aizu-Wakamatsu direction, go first in the morning to Mishima to see the autumn leaves and trains at the First Tadami River Bridge, then head on to Tadami.
In the afternoon, visit Tagokura Dam for the lake views, and on the way back you can stop at Enzoji in Yanaizu as you pass through Yanaizu.
This route is long, with lots of mountain roads and few trains, so driving or a private car is much easier than relying on the Tadami Line alone.
For Tsurugajo Castle in central Aizu-Wakamatsu, tenki.jp gives the usual peak as late October to mid-November, a little later than Tagokura, so leave half a day before or after your trip and you can see autumn both in the mountains and in the castle town.
Itinerary 3: Uonuma in Niigata and Lake Tagokura (By 3 November)
If you are coming from the Niigata direction, you can put Lake Okutadami and Lake Tagokura on two consecutive days, travelling there and back over Rokujuri-goe on National Route 252.
This combination only works until 3 November; from 4 November Rokujuri-goe is closed and you have to make a long detour between Niigata and Tadami.
Frequently Asked Questions
Q1: When are the autumn leaves at Lake Tagokura at their best?
The usual peak is roughly mid-October to early November, and we recommend late October most.
The leaves at Tagokura turn earlier than around Tadami Station and the first snow also comes early, so check the latest status on tenki.jp before you set off.
Q2: When does National Route 252 close?
In 2026, the section from the Niigata border to the Tagokura free rest area closes for the winter from 9:00 on 4 November.
The section from the Tagokura free rest area to Ishibushi in Tadami is scheduled to close around late November, after which you can no longer drive to the dam area either.
Q3: Can I get there by train?
You can take the JR Tadami Line to Tadami Station and then a taxi to the dam in about 10 minutes; we recommend booking the taxi in advance.
There are very few Tadami Line trains, so be sure to check your return time in advance.
Q4: When does Lake View Tagokura close?
In 2026 it is open until 8 November, from 9:30 to 16:00.
The introduction page says it opens on Saturdays, Sundays and public holidays, so if you are going on a weekday, check with the Tadami Information Center first.
Q5: Can I combine it with Lake Okutadami?
Until 3 November you can travel to and from the Uonuma side of Niigata over Rokujuri-goe on National Route 252 and put the two lakes together.
From 4 November Rokujuri-goe is closed, so we suggest switching to an itinerary along the Tadami Line or towards Aizu.
Q6: What should I bring to Lake Tagokura?
It is colder up there than in central Tadami, so bring a warm jacket, and from late October add gloves and a hat.
The main place to buy things around the dam is Lake View Tagokura, and once it closes for the day there are no shops, so it is best to bring your own drinks and snacks.
Final Thoughts: See Lake Tagokura in Autumn Before the Road Closes
The beauty of Lake Tagokura is that a huge dam, a deep-mountain lake and beech forest all appear in the same view, and its autumn is especially short.
When planning, remember three things: the peak is roughly mid-October to early November (best in late October), the Niigata border side of National Route 252 closes from 4 November, and Lake View Tagokura is open until 8 November.
Get these points sorted and Lake Tagokura makes the most spectacular stop on a Tadami Line trip or an autumn itinerary around Aizu and Uonuma.

There are no local buses around Lake Tagokura and few Tadami Line trains, so when you are travelling with older relatives or children, have lots of luggage, or want to link Aizu-Wakamatsu, the Tadami Line and Lake Tagokura in one day, getting around is often the most demanding part.
