Matsumoto
Matsumoto Station and Nakamachi 松本駅・中町エリア
Central Matsumoto between the JR station and the castle, taking in Nakamachi, Nawate and the Metoba river. Flat, compact and full of food, and the transport hub for every day trip in the area. This is where four of the five nights would be if you did not want an onsen.
The default base: everything between the station and the castle is inside a 20-minute walk, restaurants stay open late, and you can drop bags anywhere before a Kiso day trip. Whole apartments and renovated kominka near the station genuinely exist for five — search Airbnb for 'Matsumoto kominka' and 'Matsumoto whole house', and Rakuten Travel and Jalan for machiya-style rentals. Expect €25–45 per person per night for a whole apartment sleeping 5, well under the €70 trip budget, which is exactly what funds the two onsen nights. Business hotels (Dormy Inn Matsumoto has a rooftop onsen, Richmond, Toyoko Inn) are the fallback but violate the whole-place preference. Book Nakamachi itself if you can — a couple of the kura buildings are ryokan.
whole apartment for 5: €25–45 pp per night (¥4,500–7,500 pp) Nothing here has an onsen except Dormy Inn's rooftop bath, so if the group wants a real hot spring night you have to leave the centre. Parking is scarce and paid if you rent a car. source ↗ Matsumoto
Asama Onsen 浅間温泉
A 1,300-year-old hot spring quarter on the hillside north-east of central Matsumoto, historically the Matsudaira lords' bath. Small, quiet, with a dozen ryokan across a wide price range and a short bus ride back into town.
The recommended two-night onsen base for this trip. A dozen ryokan on a hillside 20 minutes by bus from Matsumoto Station, so you get a real hot spring, kaiseki dinner and breakfast without giving up the city. Several inns advertise free private kashikiri baths, which solves the group's mixed comfort levels with public bathing: Fujinoyu from ¥12,000 pp with free private baths and in-room meals, Kikyotei Yumotoya from ¥10,000 with six bath types, Sakaenoyu from ¥8,000, Higashi-Ishikawa from ¥13,000, Onsen Hotel OMOTO from ¥7,000. Book direct on the ryokan's own site or via Rakuten Travel or Jalan — most are absent from Booking.com and Agoda. Realistic March 2027 for five people in two rooms with two meals: ¥50,000–70,000 per night for the group, €59–82 per person per night. Ask explicitly for two adjoining Japanese rooms and confirm the private bath is included, not chargeable.
€59–82 pp per night with dinner and breakfast (¥10,000–14,000 pp) Bus from Matsumoto Bus Terminal roughly ¥350, about 20 minutes; several ryokan run free station pickups if you give an arrival time. Ryokan dinner is served early, usually 18:00–19:00, so plan the day to be back by 17:30. Nothing else is open in Asama at night — this is a stay-in evening by design. source ↗ Matsumoto
Shirahone Onsen 白骨温泉
A remote milky-white sulphur onsen in a ravine on the road toward Kamikochi, at about 1,400 m. Dramatic and famous, but in mid-March it is a long, sparse bus ride to a place where the signature public bath is closed for the season.
Assessed and not recommended for this trip, but documented so the decision is deliberate. A dozen inns in a gorge at 1,400 m: Tsuruya from about ¥14,300 per room for two, Awanoyu with the famous mixed rotenburo from about ¥49,500 for two, Yumoto Saito a 284-year-old property. The water is the best in the region — genuinely opaque, sulphurous, and unlike anything in Matsumoto. Against it: 100–120 minutes each way from Matsumoto with only about four bus connections a day, ¥3,210 one way, on the winter timetable with tyre chains fitted en route; the public riverside Notemburo is shut late November to late April so you get only your own inn's baths; and there is nothing else to do in March with Kamikochi closed. Booking is direct or via Ikyu, Rakuten Travel and Jalan. If the group insists, do it as a single night sandwiched between Matsumoto nights, not as the base.
€82–147 pp per night with two meals (¥14,000–25,000 pp) The Alpico bus runs daily year-round; the winter timetable ran 16 Nov 2025 – 16 Apr 2026 and the 2027 equivalent should cover 17–21 Mar, but it is non-reserved, tickets are same-day only, and arrival times shift with road conditions. The public Notemburo is closed until late April. Norikura Kogen next door stays bus-accessible through mid-April as a ski area, so the road corridor is open — it is the bathing infrastructure, not the road, that is shut. source ↗ Kiso Valley
Tsumago-juku 妻籠宿
The preserved post town at the southern end of the Kiso Valley, where residents signed a 1968 charter never to sell or alter the buildings. Sleeping here is the whole point: the street empties at dusk and the lanterns come on.
The best night available in the Kiso Valley and the reason to sleep in the valley at all: after 17:00 the day-trippers leave and the street is yours. Inventory is tiny, so book months ahead. Matsushiro-ya, a minshuku open since 1804 with 8 tatami rooms taking up to 25 guests, quotes ¥20,001–30,000 per room with two meals and is cash only, closed Wednesdays — bookable through Japanese Guest Houses. Shimosagaya is the other established minshuku, also on Japanese Guest Houses. Daikichi has four tatami rooms and takes bookings only via its own website. Fujioto, the most-recommended ryokan with an English-speaking owner, was listed as temporarily closed — verify before counting on it. Standard rate across the town is ¥10,000–15,000 pp with dinner and breakfast, so €59–88 per person. There is also a 200-year-old whole house in the centre of Tsumago on Airbnb sleeping a maximum of 5, which is the ideal fit if it is free. For five people, expect to book two rooms at a minshuku or take the whole house.
€59–88 pp per night with two meals (¥10,000–15,000 pp) Many minshuku are cash only and none take late arrivals — dinner is served around 18:00 and they expect you well before it. There are no shops or restaurants open at night, so book the meal plan. Bus from Nagiso Station, ¥300, 7 minutes, but infrequent; the walk from Nagiso takes about an hour on the old road. source ↗ Kiso Valley
Magome-juku and Nagiso 馬籠宿・南木曽
Magome is the uphill stone-paved post town on the Gifu side of the pass; Nagiso is the modern village at the railway station 5 km from Tsumago. Between them they hold most of the valley's whole-house rentals, and both sit on the route out toward Nakatsugawa and Kyoto.
The alternative south-valley base, and the better one if the plan is to walk Magome to Tsumago on the last morning and leave via Nakatsugawa. Magome has a handful of minshuku on the stone street at roughly ¥10,000–13,000 pp with two meals, and the bus to Nakatsugawa Station is ¥800 and 25 minutes. Nagiso, 5 km from Tsumago, has the more interesting whole-house inventory: MOUNTAinn is a designed renovation directly in front of Nagiso Station, there is a renovated 82 sqm wooden house one minute from the station with a kitchen and theatre room, and a private house from ¥17,000 per night plus ¥8,000 per extra guest above two, sleeping up to 12, about 25–40 minutes' drive from Magome and Tsumago. Whole-house rentals here run €25–50 per person per night, well inside budget, at the cost of atmosphere — you are in a working village, not a preserved one. Search Airbnb for 'Nagiso' and 'Kiso Valley'; Jalan carries the minshuku.
whole house for 5: €25–50 pp per night; minshuku €59–76 pp with two meals If you sleep here on the final night you can walk the Nakasendo in the morning and be in Kyoto by mid-afternoon via Nakatsugawa and Nagoya, saving both a backtrack and about ¥3,000 per person. Magome is in Gifu prefecture and Tsumago in Nagano, which is why the two towns are served by different bus companies. source ↗ Kiso Valley
Narai-juku 奈良井宿
The longest surviving post town on the Nakasendo, a full kilometre of Edo facades in the upper Kiso Valley with its own station on the Chuo line. Quieter than Tsumago, easier to reach, and next door to the lacquer village of Kiso-Hirasawa.
The northern post town, one kilometre long, with its own Chuo-line station — no bus needed, which makes it uniquely easy to reach with luggage. Echigoya is the oldest inn in Narai at over 200 years and the only one continuously operating since the Edo period, at roughly ¥15,000 per person, but it takes a maximum of two parties and six guests a night and allows only one consecutive night, so five people would fill it. Iseya, an 1818 wholesaler's house converted into a minshuku, runs about ¥12,000 per person with two meals. At the top end, BYAKU Narai is a converted sake brewery with its own bathhouse and two restaurants, but at roughly ¥60,000–80,000 for two it is far outside the trip's €70 per person budget. Realistic March 2027 for five in a minshuku: €70–88 per person with two meals. Book Echigoya and Iseya direct or through Japanese Guest Houses; BYAKU is on Booking.com.
€70–88 pp per night with two meals (¥12,000–15,000 pp); BYAKU Narai far higher Only worth an overnight if you want a second post-town night — as a day trip from Matsumoto it is 45–70 minutes each way and needs no bus, so most groups will do it as a day. In March expect a proportion of the shops and some inns to be closed for the winter; confirm before travelling. Echigoya's one-night-only rule means it cannot be a two-night base. source ↗
