Naruko Gorge is a 100 m-deep ravine on the Oya River in Osaki, Miyagi. Osaki City gives mid-October to mid-November as the usual colour season; on 18 October 2026 the Onsen-kyo tourism association reported the leaves had begun to show a little colour. Two short trail sections and a 2.2 km loop are open in 2026, and no trains cross the gorge this autumn. Ride the Rikuu East Line from Furukawa to Naruko-Onsen, then the Koyogo bus (26 October–8 November 2026) or a taxi.

Unless another source is named, trail rules and parking come from Osaki City’s Naruko Gorge page (updated 1 October 2026) and the 2026 gorge map, bus times from the 2026 Koyogo timetable, and train times from JR East’s October 2026 online timetable. Two tourism associations are cited: the Naruko Onsen-kyo Tourism Association (naruko.gr.jp, all five onsen areas) and the Naruko Onsen Tourism Association (welcome-naruko.jp).

What is open at Naruko Gorge in 2026

The gorge trail has an entrance at each end but is not open end to end. Two short out-and-back sections, one from each entrance, and the Ofukazawa loop from the rest house opened on Tuesday 28 April 2026 and stay open until late November 2026. Any of them may close without notice in bad weather.

The viewpoints and trails, one by one

Naruko Gorge Rest House and the observation deck

The rest house stands on Route 47 at the Nakayamadaira end, with a restaurant, a souvenir corner and toilets; in the colour season it opens 8:00 to 17:00. The deck beside it looks across to Ofukazawa Bridge, the arch that carries Route 47 over the Ofukazawa valley. On the Koyogo bus (26 October to 8 November 2026), get off at Naruko-kyo Nakayamadaira-guchi for the rest house, the deck, the Ofukazawa loop and the bridge.

Down to Kaiko Bridge

From the rest-house end, this is the only path down into the gorge: a switchback built on a cliff with a 100 m drop, about 350 m each way and roughly 30 minutes there and back, open 9:00 to 16:00. Beyond the bridge the river path is not open, so you climb back the way you came.

The Ofukazawa loop

The loop leaves the rest house, runs up the Ofukazawa valley and comes back: 2.2 km, about 50 minutes, with an azumaya rest hut at the far end. It is the only trail here open all day, though bad weather can still close it. Take care where the loop crosses the road, and stay off the slopes beside the path (Osaki City’s 2020 map).

The Naruko entrance, below the Kokeshi Museum

At the downstream end the path starts at Oya Bridge, below the Japan Kokeshi Museum, and stops 230 m in, where you turn back; it opens 9:00 to 16:00. There are toilets and a car park by the entrance, and Naruko Park, next to the museum, has a viewpoint. From 26 October to 8 November 2026, Koyogo buses stop at Naruko-kyo Naruko-guchi by the entrance and at Kokeshi-kan-mae, two minutes apart.

The train over the gorge: not this autumn

Between Naruko-Onsen and Nakayamadaira-Onsen the Rikuu East Line passes through the gorge, and the Naruko Onsen-kyo Tourism Association lists the view from trains on that stretch as a popular colour-season sight. JR East’s service status page, checked on 16 October 2026, says the line has been suspended between Naruko-Onsen and Shinjo in both directions since the July 2024 heavy rain, with replacement buses on that section. Its October 2026 timetable shows no trains from Naruko-Onsen towards Shinjo.

The Onsen-kyo association adds that trains terminate at Naruko-Onsen this autumn, that Nakayamadaira-Onsen Station cannot be reached by train, and that the view from the train on that stretch is not possible this autumn. The Naruko Onsen Tourism Association says that neither the view from the train nor the sight of trains running through the gorge can be seen.

When the trains may return. On 8 July 2026 JR East’s Yamagata regional headquarters said it now expects the repairs between Naruko-Onsen and Shinjo to be finished in fiscal 2028, a year later than its first estimate of fiscal 2027, the Kahoku Shimpo reported. Japan’s fiscal 2028 runs from April 2028 to March 2029. JR East’s service page gave no reopening date when checked on 16 October 2026.

When are the leaves at their best?

Osaki City and the two tourism associations each give a different usual window. For other places turning at the same time, see our Japan koyo tracker.

The usual windows all include late October to early November; Weathernews forecasts best viewing to begin around 28 October. The Japan Weather Association also publishes a forecast on tenki.jp.

For a visit by bus inside the published colour windows, aim for Wednesday 28 October to Sunday 8 November 2026: the range begins on 28 October, around when Weathernews expects the best-viewing period to start (a forecast that can change), and ends on the Koyogo bus’s last day.

Those dates suit a night in town before the first bus: see Naruko Onsen stays on Booking.com, then read the Naruko Onsen section below for the baths.

JMA’s Kawatabi AMeDAS station (170 m), in the Naruko Onsen area, has published normals. Averages for 1991–2020:

Getting to Naruko Gorge

Take the Tohoku Shinkansen to Furukawa and change to the Rikuu East Line, whose trains terminate at Naruko-Onsen this autumn. JR East’s October 2026 timetable has 14 locals a day each way between Furukawa and Naruko-Onsen, the same at weekends, and the ride takes about 45 minutes.

The rapid Omoide Yukemuri, normally all seats reserved, runs from Sendai to Naruko-Onsen without a change, calling at Furukawa (10:36). JR East lists it daily from 31 October to 3 November 2026 and on Saturdays, Sundays and holidays from 17 October to 29 November 2026; from 31 October to 3 November some cars are unreserved. It returns from Naruko-Onsen at 16:03 and reaches Sendai at 17:40.

From Naruko-Onsen Station to the gorge

The Koyogo shuttle runs every day from Monday 26 October to Sunday 8 November 2026. Fares are cash only; have coins ready (on board, only ¥1,000 notes can be changed). From the station it costs ¥300 to Kokeshi-kan-mae, ¥450 to Naruko-kyo Nakayamadaira-guchi (the rest house) and ¥550 to Nakayamadaira-Onsen Station. Buses can run late in traffic, so leave a margin before your train.

Each bus calls at Kokeshi-kan-mae four minutes before Nakayamadaira-guchi on the way out and four minutes after it on the way back. From Tokyo the earliest arrival is 10:06, so catching the 8:30 bus on bus days, at the rest house at 8:43 before the trail sections open at 9:00, takes a night in Naruko or the 7:06 from Sendai.

Outside the bus dates, the official options are:

Naruko Chuo Taxi is on 0229-82-2244. On foot, note that Naruko Tunnel on Route 47 has no pavement; the city’s 2020 map marks a detour. The JR replacement bus (timetable from 1 April 2026, until further notice) leaves Naruko-Onsen at 9:05, 13:15, 16:10 and 17:40, plus 10:20 on Saturdays, Sundays and holidays, and reaches Nakayamadaira-Onsen 11 minutes later. Back from Nakayamadaira-Onsen it leaves at 8:09, 11:11, 15:04 and 16:44. It can run late in traffic and may be cancelled because of road conditions.

Driving and parking

From the Furukawa interchange on the Tohoku Expressway it is about an hour along Route 47, and about 10 minutes from the onsen town; Route 47 is congested in the colour season. The rest-house car park is open mid-April to late November and charges from Saturday 10 October to Monday 30 November 2026; the dates may change.

The city counts 253 car spaces and 12 bus spaces; the 2026 map gives 250. The Naruko Onsen Tourism Association mentions free car parks a little further away.

A day trip from Tokyo via Naruko-Onsen Station

This plan works on any Koyogo bus day (26 October to 8 November 2026). Its four trains run every day on JR East’s October 2026 timetable.

If a bus runs late: the next one from Nakayamadaira-guchi is 13:32 (Kokeshi-kan-mae 13:36), and the last is 16:34, at the station at 16:48, still before the 17:15 train. If you miss the 17:15, the 18:25 reaches Furukawa at 19:13, in time for the 19:45 Yamabiko 68 (Tokyo 22:00), which keeps those times every day. On a day without the bus, take a taxi for each leg (station to rest house, rest house to museum, museum to station) and keep the same train times.

Naruko Onsen as your base

Naruko Onsen-kyo is five hot-spring areas on the upper Eai River in northern Miyagi: Naruko, Higashi-Naruko, Kawatabi, Nakayamadaira and Onikobe. Naruko, the largest, is the town around the station and has long been counted among the three famous hot springs of Oshu. Of the ten spring types used on Japanese bath signs, all but three (carbon dioxide, iodine and radioactive) occur somewhere in the area.

The town’s Onsen Shrine was built to calm the hot water that burst out in a great eruption in 837. At Higashi-Naruko the Date lords of Sendai kept a private bath, the Goten-yu, in the Edo period. By the Naruko end of the gorge, the site of the Shitomae checkpoint, a Date-domain border post, has a statue of Basho and a stone with his haiku. The Onsen-kyo association notes that Basho followed this road on The Narrow Road to the Deep North and wrote the poem at a border guard’s house while crossing the mountains beyond the checkpoint: “fleas and lice, a horse pissing by my pillow” (my translation).

Why Naruko has a culture of long hot-spring stays, and what is known about its kokeshi

Osaki City says the Naruko area has been known since early times for its many kinds of hot spring, with water coming up at point after point along the Arao River, and that a culture of toji, long therapeutic stays, grew up there. Its account of the surrounding farmland puts it plainly: in the farming off-season, people stayed at the hot springs to soothe the strain of hard work in the fields. Today the city counts five onsen areas, about 370 sources and seven of the ten categories in Japan’s newer spring-quality classification.

Kokeshi have their own local history. Miyagi Prefecture says traditional kokeshi are said to have been born in Tohoku hot-spring towns around the end of the Edo period, as souvenirs for children, and Naruko is one of the five kokeshi lineages in the prefecture. Osaki City says kokeshi are thought to have begun when woodturners who made bowls and trays also made toys for children, and that a record from 1862 already uses the word, written こふけし and read kōkeshi. When kokeshi-making started in Naruko itself is not clear, the city says, and on the evidence of documents and tradition it is put at the late Edo period.

As for the gorge, Miyagi Prefecture’s listing for Naruko Gorge says the Oya River cut it out of a plateau of quartz-trachyte tuff breccia, making a gorge 4 km long.

Takinoyu has no showers or taps and no amenities, free or for sale. There are no coin lockers and bags are not kept at the counter, but there is a safety box big enough for a wallet; borrow its key at the counter. Photography inside is banned, and when it is crowded, entry is limited and you are given a numbered ticket. Buy the bath ticket from the machine. Parking is not allowed in front of the bath or on the roads around it. The bath’s page lists the JR Naruko-Onsen station-front car park (about 300 m, 7 minutes on foot; first 30 minutes free, then ¥120 per 30 minutes) and the free Yumeguri car park (about 450 m, 9 minutes).

Kokeshi. Naruko kokeshi are said to have begun about 200 years ago, in the Bunka and Bunsei eras, as toys that woodturners in the mountains made for their children. Naruko is one of five Miyagi kokeshi lineages designated together in 1981 as a national traditional craft, “Miyagi traditional kokeshi”. The head is pressed into the body on the lathe, which is why a Naruko kokeshi squeaks when you turn its head. At the museum, craftsmen take turns at the lathe from Saturday 18 July to Sunday 29 November 2026.

Practical notes

• Clothes: at Kawatabi the average November low is 2.1°C and the high 12.0°C (JMA, 1991–2020), with 7 cm of snowfall in an average November. Bring a warm layer and shoes with grip for the Kaiko Bridge switchbacks.
• Cash: the Koyogo bus takes cash only; have coins ready. Takinoyu sells tickets from a machine.
• Bears: Osaki City’s report on 2025 says bear damage cut colour-season visitors and that the city added guards and patrols at the gorge. Check the city’s Naruko Gorge page for notices on the day you go.
