The Kiso Valley walk
Three days on foot along the old highway between Kyoto and Tokyo, through post towns that still look much as they did when the daimyo processions came through, with a train running beside the whole route in case you would rather not walk all of it.

The classic three days
Magome to Tsumago, Tsumago to Nojiri, Yabuhara to Narai
Distance
About 21 miles walking, with the train for the gaps
Seasons
April to May and October to November
Beds
Small family inns, most with shared baths and two meals
Why this walk
Who this is for
When people ask me about walking in Japan, the Kumano Kodo comes up first and the Nakasendo second. I ended up recommending the Nakasendo for a group of four who wanted a few days of walking inside a bigger trip, and the reason was flexibility. The JR Chūō Line runs along the valley floor next to the trail, so each person can decide at breakfast whether to walk the whole day, part of it, or ride to the next village and look around. Nobody has to commit the group to a 12-mile day. The Kumano Kodo is the better pilgrimage; this is the better walk for four people with four different ideas about how far to go.
The days themselves are short enough to be pleasant. The famous one, Magome to Tsumago, is about five miles over a 2,600 ft pass on stone paving and forest path, past two waterfalls and a teahouse where the volunteer host pours tea and writes walkers into a ledger. Tsumago to Nojiri is the long day, mostly on quiet lanes with one real climb. Torii Pass to Narai is the quiet one, where you may see nobody for an hour. You sleep in small family inns with dinner and breakfast, usually a shared bath, and the villages empty out by late afternoon when the day-trippers leave.
It suits people who like walking but are not out to prove anything, who would rather sleep in a 200-year-old inn than a hotel, and who can live with shared bathrooms for three nights. It does not suit anyone who needs an ensuite every night or who finds a steep stone staircase in the rain a deal-breaker, though in that case the train and the villages are still worth the detour.
How this guide was put together
I built it while planning that trip. The walk maps come from OpenStreetMap and the Japanese government's 10 m elevation model, so the surfaces and the climbs are measured rather than guessed; the inn notes come from the inns' own sites and booking calendars, checked in September 2026; the bus times from the operators' tables; and the official walking maps are linked at every point where they help. It belongs to no one trip. If you want it turned into a plan for your own dates, with the inns booked and the trains worked out, tell me what you are thinking about.
The route
Four post towns, three walks
The Nakasendo was one of the two Edo-period highways between Kyoto and Edo, and the Kiso Valley stretch (the Kisoji) is where most of it survives: stone paving over the passes, post towns with their old inns, and the valley floor shared by the river, Route 19 and the railway. Walking south to north, the days below sleep in Magome, Tsumago, Kiso-Fukushima and Narai.
The four post towns and the three walks (green dashes, drawn straight between villages). The JR Chūō Line and Route 19 follow the valley floor; the train stops that matter for a walker are marked.
The famous one: stone paving and steps up to Magome Pass, then mostly downhill on dirt forest path past two waterfalls. Nothing steep. The walk underfoot

Tsumago to Nojiri

Distances and climbs are measured along the route traced for the maps below, station to station or bus stop to village, with the small ups and downs counted. Guidebooks and AllTrails quote different figures for the same walks, some longer, some with less climb, depending on where they start and how they count.
Two sets of free official maps cover the valley, and this guide points at the right sheet of each at every walk and village: the Kiso Tourist Federation’s 45-sheet booklet, which runs the whole Kisoji from Niekawa to Magome with toilets, water and walking times on every spread, and the Nagiso Tourism Association’s maps of the southern section. See Maps and tracks to carry for what each one is and how the page links work.
The train covers the gaps. From Nojiri the local runs north through Okuwa, Suhara, Kuramoto and Agematsu to Kiso-Fukushima, the valley's main town and the easiest place to sleep after the long day. From Kiso-Fukushima it is three stops to Yabuhara for the Torii Pass walk, and from Narai five stops to Shiojiri for trains on to Matsumoto and Tokyo.
Timing
When to go
The Kiso Valley is a low-elevation historic route, not an alpine one. Its seasons are April to May and October to November; summer is hot and humid, and the June rainy season makes the stone paving slick. Narai sits at about 3,000 ft, so May days are around 70°F with nights in the high 40s, and showers are likely on any given day. The inns are not centrally heated, so a layer for the evening matters even in May.
Golden Week (the last days of April into the first week of May) is the week to avoid: Shinkansen seats sell out, the inns book out at peak rates, and the post towns fill with domestic tourists. Anything from about 10 May is clear of it and still ahead of the rains.
Crowds are a time-of-day problem on Magome to Tsumago, which is on every Japanese hiking list. Tour buses arrive mid-morning from Nagoya and Matsumoto and leave by late afternoon. Sleeping in the post towns and walking from 7 or 8 am gives an empty trail, and a weekday helps too. The rest of the valley is quiet anyway.
Underfoot
The three walks
None of the three is a mountain trail. Each is a mix of old stone paving, dirt forest path and quiet paved lane, with the mix changing day to day. Shoes with good grip are enough; the stone and the dirt both turn slick in rain. Each walk below has a map coloured by what is underfoot, an elevation profile with the steep stretches shaded, and a table of legs between the places you can leave the walk, so a walker can decide to do part of a day and take the train or bus for the rest.
Magome to Tsumago
5.3 miles, about 820 ft up and 1,320 ft down. The bus between Magome and Nagiso station runs along the road the trail keeps meeting, so every stop on it is a way out. There is no train on this stretch.

Magome. Start. The Ontake Kotsu bus to Tsumago and Nagiso station leaves Magome at 10:55, 13:25, 15:00 and 17:15 (and 9:25 in Golden Week and summer); Kitaena buses to Nakatsugawa station run about hourly.
Magome Pass (mile 1.7). Bus stop by the teahouse: the Magome–Nagiso bus stops here in both directions, about 10 minutes after leaving Magome, so the climb can end at the top.
Trail meets road (mile 2.6). An unnamed stop on the same bus road where the trail crosses it, about 20 minutes below the pass.
Koshinzuka (mile 3.9). Bus stop just past the falls turn-off, where the path rejoins the road. Same bus.
Hashiba (mile 4.8). The stop at the Ōtsumago–Tsumago road junction. Same bus, a few minutes into Tsumago.
Tsumago. End. Buses to Nagiso station (¥300, 9 min) leave the north end of town roughly every half hour to hour, last at 17:41.
Out of Magome. The trail leaves from the top of town as a stone path with several flights of steps up the hillside, with some plain dirt stretches. It crosses the main road a few times, and near the top follows a narrow lane past houses and farms to Magome Pass (about 2,630 ft).
Over the pass. Much of the other side is dirt track through cedar forest beside a stream, with mossy boulders, a few small stream crossings and an old bridge, past the Odaki and Medaki waterfalls. It rejoins the road for the last stretch into Tsumago. One walker’s verdict: nowhere on it “is it that steep.” Walking this direction has less uphill than the reverse.
Watch for. Mud and puddles on the dirt sections after rain; a short lower path has been closed by landslides before, with a signed detour. Bear bells hang along the trail to ring as you pass. This is the busy one, so the early start matters more than the footing.
On the official maps. The Kiso Tourist Federation booklet covers this walk on five spreads, south to north: sheets 41–42 (PDF page 22) Magome village and the climb out, sheets 39–40 (PDF page 21) Ichikokutochi teahouse and Magome Pass (2.5 km, about 50 min from the pass to Magome), sheets 37–38 (PDF page 20) the Odaki and Medaki falls and Kudaritani (3.0 km, about 60 min), sheets 35–36 (PDF page 19) O-Tsumago and Shinmei, and sheets 33–34 (PDF page 18) Watashima and Tsumago (4.0 km, 60–75 min). The Nagiso association’s South Kisoji Trail Map, page 1 has the whole day on one sheet with every bus stop and toilet marked and its own leg times (Magome to the pass 2.0 km, 60 min; pass to O-Tsumago 2.5 km, 50 min; O-Tsumago to Tsumago 3.5 km, 60 min), and its Tsumago-juku Guide Map, page 1 draws O-Tsumago to Magome Pass with the inns numbered and a small elevation profile.
Tsumago to Nojiri
11.6 miles, about 2,130 ft up and 1,820 ft down. Nagiso is the one real decision point: after it there is no station until Nojiri, and the climb starts within a mile.

Tsumago. Start. Buses to Nagiso station from the north end of town.
Nagiso (mile 2.2). JR Chūō Line: Nojiri is two stops north (about 10 min), Kiso-Fukushima about 35 min. Last shops and vending machines.
Shimanohashi (mile 7.2). A village bus stop in the Yogawa valley; the town community bus is infrequent and not confirmed for this day, so treat it as a last resort.
Nenoue Pass (mile 8.5). No way out at the top; on to Nojiri is the shorter side.
Nojiri. End. Trains north to Kiso-Fukushima (five stops, about 30 min) and south to Nagiso and Nakatsugawa.
Tsumago to Nagiso (about an hour). Countryside with a few small hills, on lanes and farm paths, past the Tsumago Castle ruins. This stretch has no preserved stone paving.
Nagiso to Nenoue Pass. The route takes the Yogawa path, built because the old river road kept being cut by landslides. It starts on a paved road that climbs steeply for a while, then alternates between short sections of old road, dirt mountain path and lane up to the pass. A sign on one old-road section warns of bears. The pass itself is a poor place to rest; push on.
Down to Nojiri. Mostly road downhill, with little of the old highway left.
Watch for. There are no shops or vending machines after Nagiso, so buy lunch and water there. Once the climb starts there is no station until Nojiri, so Nagiso is the place to decide; anyone who would rather skip the climb can ride one stop to Nojiri, or straight on to Kiso-Fukushima. The footing is easy; the length and the climb are what make it hard.
On the official maps. From Tsumago to Nagiso the federation booklet has sheets 33–34 (PDF page 18) (Tsumago, Watashima and the castle site) and sheets 31–32 (PDF page 17) (Kabuto Kannon, Godo, Wago and Nagiso station, 2.0 km, about 40 min). For the Yogawa route the booklet is the wrong map: its Midono to Nojiri spread, sheets 29–30 (PDF page 16), follows the old river road along Route 19 and only marks the Yogawa road as the detour. Use the South Kisoji Trail Map, page 2, which draws the Yogawa Road from Nagiso station over Nenoue Pass to Nojiri with leg times (Nagiso to Midono 3.0 km, 60 min; Midono to Yogawa 6.2 km, 120 min; Yogawa to Nenoue Pass 3.3 km, 60 min; the pass down to Nojiri 4.0 km, 90 min), and the Nagiso Historical Trail Guide, pages 3–4 for the numbered sights along it. Nojiri itself is on sheets 27–28 (PDF page 15).
Yabuhara to Narai
4.3 miles, about 1,170 ft up and 1,090 ft down. The train is the only shortcut, and it runs between the two ends: anyone who skips the pass rides Yabuhara to Narai in six minutes and waits in the village.

Yabuhara. Start. JR Chūō Line; Narai is one stop north (6 min).
Torii Pass (mile 2.3). No way out at the top: the only exits are back down to Yabuhara or on down to Narai. Decide at the station.
Narai. End. The trail comes out at the south end of the village; the station is at the north end, a 15-minute walk along the main street.
Up from Yabuhara (about an hour). Through fields and village streets, then into forest on a mix of dirt path and old stone paving, with roots and loose stones. The climb is steady and noticeable within 20 minutes, but not a scramble. The trail runs beside a forest road in places without joining it. This is the steeper side, and climbing it rather than descending it is easier on the knees.
Torii Pass, about 3,940 ft, is named for the torii gate at the top.
Down to Narai. Long and steep in places, on old stone paving and stone stairs that are uneven, sometimes loose, and slick when wet or muddy. A wooden bridge has no handrail. At the fork past the Mine-no-Chaya teahouse, take the right-hand trail down; the left branch follows the old national road and is about three times as long. Skip the shortcut staircase too, which is much steeper than the main path.
Watch for. Very few people, so carry water and snacks and keep a bell on. This is the walk where trekking poles help most, on the way down.
Season. Torii Pass is closed from mid-November to mid-April because of ice.
On the official maps. The federation booklet covers the pass on two spreads: sheets 9–10 (PDF page 6) Yabuhara village and the climb (Yabuhara to Torii Pass about 105 min, 75 min back down), and sheets 7–8 (PDF page 5), a close-up of Torii Pass with the chestnut grove, the Mine-no-chaya rest area and the water stop, and Narai from the pass to the station (Narai station to the pass about 90 min, 60 min down). Sheet 8 carries the closure note: mid-November to mid-April for ice.
Conditions change with storms. The tourist offices in Magome, Tsumago and Narai know about current closures and detours; worth a check the week before. AllTrails has recent photos and reviews for every stretch, the best way to see the ground before going.
The post towns
The villages
Magome is stone-paved and steep, rebuilt after fires, with the valley opening out below. The bus stop is at the bottom and the trail to Tsumago leaves from the top. Day-trippers arrive mid-morning. Tsumago is the preserved one: wires buried, no cars by day, and empty by 4 pm. It has only two inns now; the hamlet of O-Tsumago, three quarters of a mile south on the trail, has four more. Nagiso, the town below Tsumago, has the station, the last shops and vending machines before the Yogawa route, and a bus or taxi up to Tsumago. Kiso-Fukushima is the valley's main town, with the old checkpoint quarter, riverside onsen ryokan and the widest choice of beds, and the only inns with private bathrooms as standard. Narai is the longest post town and a working village, and few walkers get that far north. The Torii Pass trail comes in at the south end of its main street and the station is at the north end, about half a mile apart.
Luggage
The tourist information centres in Magome and Tsumago forward bags between the two towns for ¥1,000 ($6.40) per item: drop between 8:30 and 11:30, collect at the other end between 13:00 and 17:00. The service runs 20 March to November. Several inns help arrange it. For the rest of the valley the usual answer is to send the big bags ahead by Yamato's takkyubin (about ¥2,510–3,170, $16–20, for a large suitcase hotel to hotel, next day) and walk with day packs, carrying a few nights of overnight things. Forwarding from Tsumago on to Kiso-Fukushima and Narai is not confirmed. Passports, medication, chargers and a change of clothes never go in the forwarded bag.
What the inns cost
Post-town minshuku run about ¥10,000–16,500 ($64–105) per person with dinner and breakfast, and nearly all share bathrooms. The Kiso-Fukushima ryokan cost more and give every room its own. BYAKU in Narai, the one luxury inn on the route, is about ¥50,000–60,000 ($320–380) per person with two meals. Prices in this guide are at ¥156 to the dollar, as checked in September 2026.
Beds
Where to stay
The inns below are the ones worth knowing in each village, with a map of where they sit. "Recommended" and "Good alternative" are one advisor's ranking from the reviews, the rooms and how easy each is to book; the rest are listed so nothing is missed. Most book direct, by their own form, email or phone, and most load rates only three to six months ahead, so a date that shows nothing on Booking.com is usually not open yet rather than sold out.
Magome
Sleeping here means climbing out of town toward Magome Pass in the morning, before the tour buses arrive. The main street is a steep, car-free stone path; the bus stop is at the bottom and the trail leaves from the top.
Magome on the official maps: sheets 41–42 (PDF page 22) of the federation booklet, with the tourist office, toilets, parking and the Toson museum; page 1 of the South Kisoji Trail Map for the bus stops.
How Magome books. Tajimaya has its own vacancy calendar and is on Booking.com; Magome Chaya has its own calendar; Sakanomichi is on Booking.com only, and keeps its calendar closed until the owners open it. When checked on 19 Sep 2026 none had rates for the following May, and the nearest inventory on Expedia was in Nakatsugawa, 25 minutes away by bus. When Magome Chaya's calendar switches a month from 準備中 (in preparation) to prices, the others usually follow within weeks.
Booking.com is its only channel, and the owners keep the calendar closed until they choose to open it, so dates can show as unavailable long before they are sold out.
Renovated by hosts Ken and Yuki; the highest-rated inn in town on Google (5.0).
Handles vegetarian, vegan and gluten-free diets; hosts help with buses and luggage transfers.
Close to the upper end of town where the trail to Tsumago starts.
Official-site rate ¥9,240–10,780 (about $59–69) per adult with dinner (rooms of 6–10 tatami for 2–5 people); dorm bunks ¥4,950 (about $32) without meals

Dorms and private rooms; dinner is served in their restaurant across the street.
Reviews are mixed: sparse rooms and firm futons, but staff are helpful.
Tsumago village has only two inns now, each with about five rooms. The O-Tsumago hamlet, three quarters of a mile south on the trail from Magome, has four more, passed on the way in; sleeping there adds 15–20 minutes to the next morning's start.
Tsumago on the official maps: the Tsumago-juku Guide Map, page 2 is the one to carry, a street plan of the village with every inn, restaurant and shop numbered, the three parking lots, the bus stops and the ATM hours; page 1 of the same map lists the O-Tsumago inns with phone numbers. The federation booklet has the village on sheets 33–34 (PDF page 18).
How Tsumago books. None of the six inns below is on Booking.com, Expedia or DirectBooker; every one books direct by phone, email or its own form, and none says how far ahead it opens. Tsutamuraya is the only one with a public availability calendar. Daikichi caps every room at two guests and takes no two-night stays. Matsushiroya will not take a direct booking from overseas guests, so it goes through the Tsumago Tourist Information Centre (0264-57-3123, nagiso@ju.kiso.ne.jp, 8:30–17:00). Two further village inns not mapped here take phone bookings only: Shimosagaya (下嵯峨屋, 0264-57-3124, about ¥9,100, $58, with meals) and the minpaku Uechoujiya (上丁子屋, 090-8734-2880). Fujioto has been closed since 1 June 2024 with no reopening date (notice).
¥12,500 (about $80) per person with two meals, ¥9,900 (about $63) room only (tax in; +¥500–1,000 (about $3–6) on peak dates; +¥200 (about $1.30) lodging tax from June 2026)

Reviews are the most mixed here (3.9 on Google): noise and thin futons come up.
The Tsumago to Nojiri walk ends at Nojiri; the local train runs five stops north to Kiso-Fukushima, which has the valley's largest choice of inns and the only ones with private bathrooms as standard. Two of the inns below stand along the river in the old town, about half a mile from the station; one is at the station door.
Kiso-Fukushima on the official maps: sheets 13–14 (PDF page 8) of the federation booklet, the Fukushima checkpoint and the old town; the inns are not marked.
How Kiso-Fukushima books. This is the one village on the route where the inns behave like hotels: all four sit on Jalan and JTB, and three run their own booking engines on reserve.489ban.net, so availability can be checked online rather than by phone. Mikawaya loads its calendar furthest ahead (eight months out in September 2026); the three ryokan load late, so expect them to open in the winter for a spring date. With 11 to 26 rooms each, a weeknight in May is not usually tight once the calendars open.

Check-in 15:00, out 10:00. Bus stop at the door, 10 min walk from the station. Jalan guests rate it 3.9, lower than the other three.

Booking
Was already taking bookings eight months out when checked on 19 Sep 2026, a room for two at ¥18,200 ($116) direct. Book on its 489ban engine or phone 0264-24-3332 (10:00–23:00). Check-in 15:00 (until 23:00), out 10:00. 100% charge for same-day cancellation or no-show.
Simple onsen hotel across the river and the easiest to book in town.
Every inn is on or just off the one street. Narai fills up in spring and autumn, so book early for May. BYAKU is the exception to everything else in the valley: a 16-suite luxury inn across four restored buildings, adults only, with dinner next to the revived Suginomori sake brewery.
Narai on the official maps: sheets 7–8 (PDF page 5) of the federation booklet, the village from the station to the Torii Pass trailhead with the tourist information office, toilets and the Kiso Great Bridge.
How Narai books. BYAKU's own engine opens about six months out and its popular nights sell out early, so a May date wants booking the day it opens, around late November. None of the minshuku has a calendar to poll; Iseya takes an online form and cards, Shimada a form, Echigoya and Ikariya phone or email only. La Terra is on Expedia and Booking.com. The Narai-juku Tourism Association (0264-34-3160) books Toge-no-yado Aoki and Minshuku Kato, two inns not mapped here; Misatoya is a house on Airbnb.
About ¥50,000–60,000 (about $320–380) per person with two meals
Bathrooms
Private bath in every room (semi-open-air in most, open-air with sauna in the top suites); spring-water bath (not onsen)

Booking
Was already taking bookings eight months out when checked on 19 Sep 2026: Expedia had a room for two at about $723 ($795 with fees); also on Booking.com.
Takes 2 groups at a time; Italian–Japanese fusion food rather than kaiseki.
Reviews are mixed (3.9): design praised, service and practical details criticised.
Book direct, early. Most post-town inns aren't on booking sites; reserve by their website, email or phone. None of the Tsumago or O-Tsumago inns is on Booking.com at all. If an inn only takes phone bookings, the Tsumago Tourist Information Centre (0264-57-3123, nagiso@ju.kiso.ne.jp, 8:30–17:00) will call on a guest's behalf. Travel Arrange Japan (Emilia Travel) and Kiso Adventures also broker these inns; see Other ways to book below. Kiso-Fukushima is the exception: its ryokan are on Jalan and JTB and run their own online engines, so that night can be booked from a browser.
Calendars open late. The post-town inns load rates only three to six months ahead, so for a spring date expect their calendars to open in the winter; "no availability" on Booking.com before then means the dates aren't loaded, not that they're sold out. Booking.com has no public API or feed for this, so the reliable moves are the inn's own vacancy page, a message to the property through its Booking.com listing, or a phone call. Tawaraya (旅籠 俵屋), a whole-house rental in Magome not listed below, books through tabichat.jp.
Shared bathrooms are the norm. In Magome, Tsumago, O-Tsumago and Narai, expect shared toilets and a bath used in turns or booked in a time slot. Only the Kiso-Fukushima ryokan, BYAKU and Yanagiya give every room its own.
Bring cash. Tsutamuraya and Maruya are cash only, Matsushiroya takes cards for the room but not the new ¥200 (about $1.30)-per-person lodging tax (from June 2026), and Nagiso and Narai stations sell paper tickets only.
Dinner matters. Book two meals wherever it's offered. Village restaurants close early, and some inns (Nedoko, Yanagiya) help reserve dinner elsewhere.
Other ways to book
Three services can take some or all of the booking off a walker's hands. The trade-off is price: one charges a small fee per inn, the other two sell a packaged walk at a large premium. Booked direct, four nights with two meals come to about $370 per person with a minshuku in Narai, or about $600–650 with BYAKU, plus roughly $40 of luggage transfers and $30 of local trains and buses.

Best for
Travel Arrange Japan (Emilia Travel, Osaka)
A licensed Japanese agency that books individual inns by request, and will build a custom itinerary. Of the inns in this guide, Tajimaya, Matsushiroya and Hanaya were on its list on 19 Sep 2026. It also takes requests for inns it doesn't list.
About ¥1,100 ($7) per person per night. Matsushiroya is from ¥13,200 ($84) through them against ¥12,100 ($77) direct.
The phone-only inns, especially Matsushiroya, which tells overseas guests to book through them or the Tsumago Tourist Information Centre.
Kiso Adventures (nakasendo-kisoji.com, based in Narai)
A small local operator selling self-guided walks: inns with dinner and breakfast, English route notes and maps, luggage coordination and phone support. Luggage fees are paid locally. Taking inquiries for December 2026 and 2027; no solo travellers.
The 4-day walk (3 nights, with Kiso-Fukushima) is from $800 per person, sharing. Booked direct, those three nights cost about $300, so roughly $500 per person more.
A fallback if the post-town calendars fill first. They say they can secure inns that are hard to book independently.
Oku Japan
The established self-guided walking operator. The 5-day Nakasendo package has 4 nights on the trail with meals, rail tickets from Kyoto or Tokyo and back to Tokyo, maps and phone support. Luggage transfer is extra. Its route has no Magome night and finishes in Karuizawa.
About £1,315 (roughly $1,700) per person on the current listing, against about $600 self-booked for the equivalent nights: a premium of roughly $1,100 per person.
Travellers who want everything handled.
Booking direct wherever an inn has a form, email or online engine is the cheapest route. Travel Arrange Japan makes sense for Matsushiroya or any phone-only inn, where $7 a night buys a Japanese-speaking agent, and Kiso Adventures is the fallback if the post-town calendars fill first.
Everything needed to make the calls, in one place. From the US dial +81 and drop the leading 0. Japan is 16 hours ahead of Pacific time, so a 9 am call from the US west coast reaches an inn at 1 am; call between 4 pm and 11 pm Pacific to land in their morning and afternoon.
From the south the way in is the limited express Shinano from Nagoya to Nakatsugawa and the bus up to Magome. From the north it is the Azusa or a local to Shiojiri, then the Chūō Line down to Narai. Point-to-point tickets for the whole valley come to a few thousand yen, so no rail pass pays for itself here. The Kiso Valley locals are infrequent, so the day plans need to be built around timetables rather than the other way round.

The buses
Two bus routes matter, and neither takes reservations or the Japan Rail Pass. The timetables below are japan-guide's copies of the operators' tables (Ontake Kotsu as of 1 April 2026, Kitaena as of 1 October 2026); the operators change them in spring and autumn, so check the week before.

The pass stop is about 10 minutes out of Magome on the Tsumago bus, which is what makes it a way to end the climb at the top. Sources: japan-guide's Kiso bus page (updated 5 May 2026) and Go! Nagano's Kiso timetables, whose copies date from 2020 and differ by a few minutes.
Maps and tracks to carry
The maps above show what is underfoot and where to bail out; for navigating on the day, the official maps are better, and they are free.
The Nagiso Tourism Association’s maps and brochures page, all in English: the South Kisoji Trail Map (2024, two sheets: page 1 Nagiso station, Tsumago and Magome with every bus stop and toilet, page 2 the Yogawa Road to Nojiri and the Kakizore valley, both with leg distances and times); the Tsumago-juku Guide Map (2023; page 1 O-Tsumago to Magome Pass with the inns and luggage forwarding, page 2 the village street plan); and the Nagiso Historical Trail Guide (four pages, Magome to Nojiri via Tsumago and Midono, with 33 numbered sights). No bus timetable among them; the association answers on 0264-57-3123.
The page links above open the PDF at the right page in desktop browsers and in Chrome on Android. Safari on an iPhone or iPad ignores the page number and opens page 1, which is why each link also names the sheet.
Ridgeline Images publishes GPX and KML tracks for five day-stages through the valley, alongside its paid guidebook, for Gaia GPS, AllTrails or Maps.me. Download the stages before going; phone signal drops on the Yogawa route and over Torii Pass.
AllTrails has recent walker comments on mud, detours and closures for each stage, linked under each walk above.

I am Kevin Rugg, a travel advisor in the San Francisco Bay Area, and this guide is the research I did for my own clients. Planning a walk here is mostly a matter of timing: the inns open their calendars late and fill early, the valley trains are infrequent, and the bus over the pass runs four or five times a day. If you would like the dates, the inns and the trains worked out for your group, or a second opinion on a plan you have already made, tell me what you are thinking about. I will get back to you within a day.
