Senshinkan Matsuya sits near the middle of Shibu Onsen, the stone-paved hot spring town in Yamanouchi, Nagano, close to the Jigokudani snow monkeys. It is a small, family-run inn in a three-story wooden building that keeps its early Showa look. Before you book, three things matter: the two indoor baths are reserved in 50-minute slots at check-in; dinner starts at a set time and a late arrival means no dinner and no refund; and the official pages differ on a few details, such as the latest arrival time and how you pay, so confirm them with the inn.

Why is it called Senshinkan?
The greeting page says each head of the family takes the name Eihachi. In the time of the eighth head, Takahashi Deishu, one of the shogunate’s “Three Shu”, visited Shibu Onsen and called the inn a house where the heart is washed. That is the meaning of Senshinkan, the name he gave it.
The inn calls itself small, and its rooms are all different, decorated to follow the Shinshu seasons.
Rooms at Senshinkan Matsuya: what to expect
What is in the room?
All rooms have heating and air conditioning, a TV with satellite channels, an empty refrigerator, a small safe and a tea set. Wi-Fi works in every room. The amenities list a bath towel, a face towel, one yukata per person, a toothbrush and a razor. Your futon is laid out before you arrive and stays out until checkout.
Is there a toilet in the room?
Most rooms have no private toilet; the inn says the toilets on each floor are close to the rooms. On the booking page, each room name says whether it has a toilet, so check before you choose.
Are there stairs?
Yes. The building is old and has no elevator, and the rooms are on the 2nd and 3rd floors. The inn asks guests who worry about stairs to travel with a companion. The baths are in the basement.

How do the reserved baths work?
Since December 2022, the two indoor baths have been reserved by slot instead of split by gender. You book a 50-minute slot when you check in, first come, first served, and the inn says it will help you rebook if needed. The baths open from check-in in the evening and again from 6:00 to 9:50 a.m. The official site and the booking page give different closing times for the evening, so ask at check-in. Shampoo, conditioner and body soap are provided.
Is the water hot?
Yes. The inn says the spring water pours in very hot, so adjust the temperature to suit you before you get in. The water is 100 percent free-flowing natural hot spring water.
Can I bathe with a tattoo?
The official pages do not mention tattoos. The indoor baths are reserved for your group, but ask the inn before you book. Our tattoo and onsen guide explains what to ask.
How do the nine public bathhouses work?
Guests of Shibu Onsen inns can visit the town’s nine public bathhouses for free, from 6:00 a.m. to 10:00 p.m., with a key that opens all of them. The inn sits near the middle of town: the eighth bath, Jinmei-taki-no-yu, is right in front, and the ninth, Shibu Odayu, is next door. The bathhouses have no washing area, so the inn asks you to wash in its own baths, and they close for cleaning. The inn also rents colored yukata for a fee.
Meals at Senshinkan Matsuya
What are dinner and breakfast like?
On the booking page, the dinner plan is a Shinshu beef sukiyaki set with rice, miso soup and pickles, brought to your room, from 6:00 or 6:30 p.m. Groups of three or more may eat in a private dining room. The plan includes a free breakfast on request at check-in: a Japanese breakfast box made by the landlady, about six dishes, also served in the room from 8:00 or 8:30 a.m. The plan needs booking at least 3 days ahead.
If you miss the dinner start time, the inn treats dinner as canceled and the price stays the same, so it suggests a room-only or breakfast plan if your timing is tight.
Can the inn handle allergies or a special diet?
No. The official site says it does not offer individual meals such as vegetarian, and the dinner plan says it does not handle allergies or individual requests.
Booking, cancellation and taxes at Senshinkan Matsuya
What is the cancellation policy?
The official site lists these fees: 20 percent of the room charge 4 days before; 50 percent from 3 days before to the day before; and 100 percent on the day or for a no-show. Group bookings are handled separately. The booking page shows its fee only after you pick a date, so read it before you confirm. Our guide to hotel cancellation in Japan covers the common terms.
How do I pay, and what do children cost?
The official site and the booking page describe payment differently, so confirm how you will pay when you book. The booking page has options for children aged 6 to 12, 3 to 5 and under 3, but we could not read the child rates. Ask the inn.
What taxes are added?
Yamanouchi Town charges a bathing tax of 150 yen per guest aged 12 or over per night. Since June 1, 2026, Nagano Prefecture charges an accommodation tax of 200 yen per person per night for the first three years, when the room-only price is 6,000 yen or more before consumption tax. The inn’s pages do not say whether these are included. See our onsen bathing tax guide.
Getting to Senshinkan Matsuya in Shibu Onsen
From Tokyo Station, the inn’s access page gives this route: the Hokuriku Shinkansen to Nagano, the Nagano Electric Railway to Yudanaka, then the bus bound for Kanbayashi to the Shibu Onsen Wagobashi stop, a 1-minute walk from the inn. By car, it is via the Shinshu-Nakano interchange. The inn has its own covered car park a short walk away, first come, first served; if it is full, you use the paid town parking at your own cost. Ask in advance about pickup.
For the snow monkeys, the inn’s page says it is about 9 minutes (2.8 km) by car from Shibu Onsen to the monkey park car park, but the road is closed from December to March except to the shuttle bus. Another way is via Kanbayashi Onsen: about 5 minutes to the trailhead, then about 30 minutes on foot. See our snow monkey park guide.
