Naruko Gorge in Autumn: Trails, Buses and Onsen Stops

Plan Naruko Gorge around the 2026 trail season, Momiji-go bus dates, replacement buses and onsen hours. Check which paths are open before you go.

YUBIYORI Editorial TeamUpdated September 27, 2026

The easiest way to misplan a foliage day in Naruko is to treat the gorge, Nakayamadaira, the station district and its baths as one compact walking area. The Naruko Onsen–Shinjō rail section remains suspended after the 2024 flooding, so reaching Nakayamadaira means using a JR replacement bus or arranging another ride. Meanwhile, autumn traffic on Route 47 can affect buses and taxis as well as drivers.

If you remember one thing, make the gorge and Nakayamadaira the morning’s main activity, then bathe in the afternoon. The gorge paths have limited hours; most baths stay open later. Reversing the order can leave you reaching the trail near its 4 p.m. closing time.

Osaki City pages give the usual Naruko Gorge foliage window as late October to early November on one page and late October to mid-November on another. Treat that as a typical range, not a prediction for a particular date.

First decision: gorge first or onsen first?

For most foliage trips, go to Naruko Gorge first. Osaki City lists the 2026 trail season from April 28 through late November, with the short gorge paths generally open from 9 a.m. to 4 p.m. The Nakayamadaira-side route from the entrance to Kaerimibashi is about 350 metres one way; the Naruko-side route is around 230 metres one way. Both are out-and-back walks. The Ofukazawa trail is a longer loop of about 2.2 kilometres. Weather can close any path without notice.

Route 47 congestion is another reason to leave the baths for later. It can affect buses, taxis and shuttles, not just cars. If you spend the morning at Takinoyu, stop for lunch and only then head toward Nakayamadaira, you may reach the gorge at 2 or 3 p.m. The paths may still be open, but your return and any second bath become harder to fit.

For the current transfer details, see the Naruko-to-Nakayamadaira car-free day guide.

Second decision: how to get there without a car in 2026

The seasonal Naruko Gorge–Nakayamadaira Momiji-go bus is scheduled for October 26–November 8, 2026. It links Naruko Onsen Station with the Japanese Kokeshi Museum, the Nakayamadaira-side gorge entrance, Shintoro-no-yu and Nakayamadaira Onsen Station. Miyagi Kotsu lists it as a non-reservation, first-come service. Traffic can delay it, and a busy bus may leave some passengers behind. Check the latest timetable before setting out; the operating period is shorter than the foliage season.

Outside those dates, Nakayamadaira is reached via the suspended Naruko Onsen–Shinjō section of the Riku-East Line, where JR East operates replacement buses. The April 1, 2026 timetable is in effect. The western section between Naruko Onsen and Shinjō remains a bus replacement; the eastern section toward Kogota is rail, though heavy rain can still cause disruption.

The replacement bus has no toilet. If buying a ticket on board under the applicable rules, carry exact cash; the bus cannot make change. Allow time for waiting, boarding and the final walk rather than relying on the nominal drive time alone.

If you would rather skip the replacement-bus leg, a taxi from Naruko Onsen Station to the gorge is about ten minutes according to Osaki City. That short ride still needs to be planned during peak traffic.

Third decision: what is confirmed about parking and transfers?

The Nakayamadaira-side car park is normally in use from mid-April through late November and closes for winter. For autumn 2026, Osaki City lists paid parking from October 10 through November 30:

Vehicle	Parking fee
Standard car, including kei cars	¥500
Medium vehicle	¥1,000
Large vehicle	¥1,500
Motorcycle or motorised bicycle	¥200

Route 47 congestion is expected during peak foliage. Check the city’s latest notice before departure in case access or fees change.

The accommodation-only Naruko Onsen taxi discount ran from June 26 through September 30, 2026. Each coupon was worth ¥500; under eligible conditions, two could be used for a total discount of up to ¥1,000 for specified destinations including the gorge, Katanuma and the Japanese Kokeshi Museum. It ends before the main late-October foliage period, so do not build an autumn budget around it.

This is why seasonal deals and peak foliage do not always line up. A promotion that works in September is not automatically available in late October.

Fourth decision: the 350-metre path or the 2.2-kilometre Ofukazawa loop?

You do not have to walk farther for the visit to feel complete. The Nakayamadaira entrance to Kaerimibashi is about 350 metres one way and suits a first visit or a day that also includes a bath. It gives you the main gorge scenery while keeping the return time manageable.

The Ofukazawa trail is about 2.2 kilometres and makes more sense if forest walking is the main activity. Add lunch, a bath in Nakayamadaira and the transfer back to Naruko, and the day becomes substantially longer. Trail status can change after rain, so check before committing.

With an older guest, a young child, stroller or wheelchair, do not assume that “only 350 metres” means an accessible route. See the Naruko family and older-traveller mobility guide. If rain persists, the gorge paths can close without notice; use the rainy-day Naruko plan and keep the itinerary near the station instead of searching for another hillside trail after you arrive.

Fifth decision: where to bathe after the gorge

If you finish the gorge walk in Nakayamadaira and your return transport is settled, Shintoro-no-yu is the natural final stop. If you have already returned to central Naruko Onsen, Takinoyu is beside the station area; there is little reason to ride west again just to add another bath. Here are the listed hours and standard admissions for the three options:

Bath	Listed hours	Last admission	Adult	Child
Shintoro-no-yu	9 a.m.–8:30 p.m.	Not listed	¥500	¥250 for elementary-school children; preschool children free
Takinoyu	7:30 a.m.–9 p.m.	8:30 p.m.	¥300	¥100
Waseda Sazikiyu	9 a.m.–9:30 p.m.	9 p.m.	¥660	¥330

Shintoro-no-yu uses 100% source-flowing water and has a listed pH of 9.3. Waseda Sazikiyu also has a large rest room and a private outdoor bath. Its status needs particular care: Osaki City’s September 18, 2026 notice says it is temporarily closed until further notice for maintenance on the spring supply. Check for a reopening notice before planning a visit; the usual hours and rates above do not mean it is currently operating.

For spring details and a facility-by-facility comparison, see the Naruko day-use onsen guide. For a lower-cost visit, see Naruko on a budget, including towel costs; tattoo questions are covered in the Naruko tattoo-policy guide.

An extra 2026 risk: do not use the Miyagi Olle course as a foliage backup

Osaki City’s August 5, 2026 update says heavy rain on August 1 caused several landslides and flooding along river areas. The entire Miyagi Olle Osaki–Naruko Onsen course is closed until safety checks are complete.

The tourism association’s August 16 notice still listed a November 8 “Feeling Walking 2026” return event. That announcement does not prove the course will have reopened. Until Osaki City confirms the safety check and formally lifts the closure, do not treat the event listing as permission to walk the route.

Keep the two trail notices separate: the 2026 Naruko Gorge paths are listed as open for the season, subject to weather closures; the Miyagi Olle course has a separate full closure after the heavy rain.

The most reliable day trip: choose foliage-first or bathing-first

Foliage first

Go to Nakayamadaira and the gorge in the morning. Walk the 350-metre main section, adding Ofukazawa only if the trail is open and you have time. Have lunch and bathe at Shintoro-no-yu, then return to Naruko Onsen. If the return is delayed, skip a second bath rather than miss the transport back.

Bathing first

If foliage is a bonus rather than the main reason for the trip, stay based around Naruko Onsen Station. Check the transport status, visit the gorge if timing permits, then use Takinoyu near the station. Add Waseda only if it has officially reopened and the schedule allows. This version is easier to shorten when traffic builds.

If you are undecided about making a day trip, compare a Naruko day visit with an overnight stay.

Is an overnight stay more worthwhile in foliage season?

More than on a typical day, the answer leans yes if you want both the gorge and a proper bath. Traffic and transfer uncertainty can squeeze the gorge, lunch, bathing and return into the same day. Staying overnight lets you split them: bathe in central Naruko on arrival and visit Nakayamadaira the next morning, or see the gorge on day one and take Takinoyu’s 7:30 a.m. opening the following day.

For lodging location, compare the Naruko stay-area guide. Nakayamadaira suits a foliage-first trip if you are comfortable with the replacement transport; the station area is usually easier with luggage and gives more flexibility for meals and onward travel. Travelling with a child or older guest? Use the mobility guide. Early arrivals and late departures may also benefit from the morning and evening bath guide.

Final checks for a 2026 visit

One or two days before you go, check more than the foliage forecast:

Osaki City or the Naruko tourism association’s latest foliage update.
Whether the gorge paths are open.
Any service disruption on the Kogota–Naruko Onsen rail section.
The day’s replacement-bus timetable between Naruko Onsen and Nakayamadaira.
Whether the seasonal Momiji-go is running on your date.
The current paid-parking period and access conditions.
Whether Waseda Sazikiyu has reopened.
Whether Osaki City has lifted the Miyagi Olle closure.

The short version

Naruko Gorge’s usual foliage window is late October to early or mid-November, but check the current colour report. For a car-free trip, use the 2026 JR replacement bus as the baseline and treat Momiji-go as date-specific. Visit the gorge before bathing, then choose Shintoro-no-yu if you are still in Nakayamadaira or Takinoyu if you have returned to the station area. The Miyagi Olle course remains closed under a separate post-rain notice unless Osaki City announces otherwise.
