Oku-Aizu

Tohoku, Japan · Countryside / satoyama, Town / small city, Snow

Four mountain villages in inland Fukushima threaded together by the Tadami river and by a railway that spent eleven years severed. The line came back whole on 1 October 2022 and crosses eight bridges over the river; the first of them, the one in the photograph everyone has seen, is looked at from a viewpoint you climb steps to in Mishima, not from the carriage window. It snows here for half the year and three or four metres pile up on the flat, and everything else comes out of that snow: the beech forest that led UNESCO to make 78,032 hectares a biosphere reserve in 2014, and a winter basketry tradition using mountain fibres that the state recognised as a national craft and that goes back, with excavated remains, to the Jomon. In the next village along they grow the nettle whose fibre becomes the linen of Echigo. And there is a rowing boat that crosses a stretch of river where, in summer, the mist comes up.

The essentials

Getting there

Car — You have to choose between the train, which is the reason to come, and the car, which is what lets you move. The Tadami Line is 135 kilometres from Aizu-Wakamatsu to Koide with three trains a day over the whole run: that gets you here, but it does not get you round four municipalities. By car, Aizu-Kawaguchi sits on national route 252 and from there Mishima is a quarter of an hour, Tadami a long twenty minutes and Showa another quarter of an hour up the next valley. The sensible plan is to ride the stretch of line that matters in one direction and do the rest by car. Without a car there are the district buses, which are few and have traps: the one up from Aizu-Tajima to the Showa museum does not run from 1 November to 30 April, and Mishima's town bus does not run on Sundays or public holidays. In winter the snow decides: three or four metres on the flat, roads that are cleared but that want winter tyres, and a snow season half a year long.

Frequently asked questions about Oku-Aizu

What to do in Oku-Aizu: 11 activities

• The first Tadami bridge, from the viewpoint 1.5 h must-see Mishima · 15 min

  The image that made the Tadami Line famous is not taken from the train: it is taken from across the valley. The path leaves the car park of the Oze Kaido Mishima-juku roadside station on national route 252, and Mishima town says the viewpoint is a five-minute walk up a flight of steps that starts beside the tunnel. At the top there are three positions, which the town calls B, C and D, at different heights above the valley. There is no charge. What to check before you climb is the timetable: three trains a day run the full route through here, and the town publishes a table of the times the train crosses the bridge. Go up without it and you will see an empty bridge, which is also fine but is not what you came for.

• The line that spent eleven years cut 4 h must-see

  A hundred and thirty-five kilometres of single track from Aizu-Wakamatsu to Koide, eight bridges over the Tadami between Aizu-Nishikata and Aizu-Gamo, and three trains a day over the full run. The stretch between Aizu-Kawaguchi and Tadami was severed by the July 2011 floods and did not reopen until 1 October 2022: eleven years. With three trains a day, boarding without the timetable in hand means four hours at a station with nothing around it, which is exactly why this is a journey to make on purpose rather than in passing. From the Oku-Aizu end the sensible move is one leg by train and back by car.

• The rowing boat in the gorge of mist 2 h booking Hayato, Kaneyama · 15 min only from mid-April to late November

  In the Sanzara hamlet of Kaneyama, people used to cross the Tadami river in a hand-rowed ferry to get on with daily life. That boat was revived under the name Mugenkyo no Watashi, the crossing of the gorge of illusion, and a boatman rows it. It leaves from the landing next to Hayato station. The 2026 season began on 18 April and the winter closure before it ran from 1 December to 17 April. It runs from 9:00 until sunset, with 7:00 and 8:00 departures added from June to September. You book five days ahead and the boat goes out for your group alone, never shared: the 45-minute cruise is ¥6,000 for two or ¥3,000 a head from three people, and the 90-minute version with a walk is double that. Six fit in a boat and there are three boats. Two warnings from the operator itself: it can be cancelled on the day depending on the river, and the landing on the far bank is called off if there are bears about. The mist the place is named for comes up in summer.

• Oku-Aizu winter basketry 1.5 h Mishima · 15 min

  Three mountain plants and nothing else: hiroro, a sedge from upland wetlands whose leaves are twisted into cord and woven as fine as lace; wild grape bark, cut around June and used for bags and carrying baskets; and matatabi, whose finely split branch makes the kitchen strainers and sieves, gathered from early November to early December. Nothing is dyed: the colour is the plant's. It was made in winter, when the snow allowed nothing else, and has been off-season work since the Edo period. How old it is comes from an excavation: at the Arayashiki site, in Mishima itself, woven remains from the Late Jomon turned up using the same two-over twill still used for grapevine baskets today. The state designated it a traditional craft on 10 September 2003.

• The biosphere reserve and the beech forest 3 h Tadami · 25 min

  UNESCO inscribed a biosphere reserve here on 12 June 2014: 78,032 hectares covering the whole of Tadami town and part of Hinoemata village. It is split three ways: a 3,557-hectare core where you generally do not go, a 51,333-hectare buffer under two regimes, and a 23,142-hectare transition zone with fields, forest and houses. What it protects is a snow-country beech forest and a relief the town itself calls snow-eroded: avalanches and geology have eaten into the mountains until the bedrock shows, and the beech keeps to the stable lower slopes while the avalanche ones carry scrub. The town had already declared itself the natural capital of Japan in 2007, seven years earlier.

• The craftspeople's fair, in June 3 h Mishima · 15 min only the second Saturday and Sunday of June

  The second Saturday and Sunday of June: that is what JR and the town publish, though in 2025 it fell on the weekend before, so check your year. In the oak grove in front of Mishima's crafts centre some 150 makers set up from all over Japan, under the motto from the hand that makes to the hand that uses: Oku-Aizu braided basketry, which is the local craft, plus wood, ceramics, glass and metal among others. Saturday 9:00 to 16:00 and Sunday 9:00 to 15:00. It has run since 1986, when the centre opened. There are workshops to try things and, since 2026, a voluntary contribution box; nobody publishes an admission price. On foot it is fifteen minutes from Aizu-Nishikata station, and Aizu-Miyashita has a free shuttle on those two days.

• The nettle that becomes the linen of Echigo 1.5 h Showa · 25 min

  Karamushi is a plant of the nettle family whose stem fibre, just under the skin, is what gets used: absorbent, quick-drying, strong, and stronger still when wet. Showa village has grown it without a break since the Edo period, and the detail that changes everything is where it goes: the economy ministry names it as the raw material for Echigo-jofu and Ojiya-chijimi, two celebrated textiles of neighbouring Niigata. Which is to say part of their prestige starts in the fields here. The process is three jobs: stripping the fibre by hand with purpose-made tools, spinning it by splitting it into fine strands and joining them with twist — tighter for the warp than the weft — and weaving it on a floor loom with the warp held at the waist and the right foot working the heddles. From harvest to finished cloth takes over a year for a single obi or kimono. The state designated it a traditional craft on 30 November 2017.

• The workshop where it is still made 1.5 h Mishima · 15 min

  Mishima did something unusual: in 1981 it declared itself a movement. The everyday-crafts movement has a ten-clause founding charter and, from 1986, a building, the Seikatsu Kogeikan, which is at once a shop for what the village weaves and the place to learn how. There are basketry and woodworking classes, and short sessions from half an hour for anyone who just wants a go. Open 9:00 to 17:00, closed Mondays or the following day when Monday is a holiday. A warning from the centre itself: coming from Yanaizu, do not cross the Aso bridge however much the satnav insists, stay on national route 252.

• Half a year of snow 1 h Tadami · 25 min only snow from late November to early April

  It is worth knowing what you are walking into. In Tadami it snows from late November to early April and in places the snow lingers into early May: a six-month season. On how much piles up, two publications from the same town hall disagree: its website gives an average of two to three metres and its document on the UNESCO park says three to four metres even on flat ground. The website adds that annual snowfall exceeds 1,200 centimetres. This is not an inconvenience of the trip, it is the trip: out of that snow come the beech forest, the basketry that was made in winter because nothing else could be, and the contrast of new green against old snow that shows in spring on the mountains around Lake Tagokura.

• The karamushi museum 1 h Showa · 25 min

  Inside Showa's roadside station, the museum tells the relationship between people and this fibre from the Jomon on: cultivation and processing tools, documents, cloth and a video library. Outside it has a garden of textile nettles from around the world that you can walk round freely. Three hundred yen from high-school age and ¥150 for primary and junior high. Open 9:00 to 17:00 with last entry at 16:30; from April to November it opens every day and from December to March it closes on no fixed day. Forty parking spaces. On public transport there is a detail worth checking first: it is 35 minutes by bus from Aizu-Kawaguchi station, but the bus up from Aizu-Tajima does not run from 1 November to 30 April.

• The museum of the beech and the river 1.5 h Tadami · 25 min

  If the beech forest is why this is a biosphere reserve, this is where it gets explained: dioramas, specimens of the valley's plants and animals, and the part about how people lived inside that forest. Three hundred and ten yen from high-school age and ¥210 for schoolchildren, cash only, and the ticket also covers Furusato-kan Tagokura, the museum holding the memory of the village that went under the reservoir. Open 9:00 to 17:00 with last entry at 16:00, closed Tuesdays (or the next working day when that is a holiday) and over New Year. Twenty-five minutes on foot from Tadami station.
