A 140-year-old kominka in the 41st post town on the Nakasendo — built in the style of a samurai inn, still home to the people who live here. Stay where the road has run for centuries.
Book direct, skip the platforms — and deal with real people, not a front desk. We host you ourselves, from the first message to the last morning. Two rooms in one kominka; pick the one that suits you.

Staying with us? Dinner and breakfast are reserved separately — see the Food option section just below.

Meals at Kashiwaya are optional and reserved in advance — a traditional nabe dinner and an ochazuke breakfast, cooked around any dietary needs. Reserve through our pre-arrival form.

Most travellers pass through Tsumago and Magome and never see what happens after the buses leave. Kashiwaya is for the ones who stay — who eat what the family eats, drink what the locals drink, and sleep in a house that has watched the road for 140 years.
Kashiwaya sits in Midono-juku — the 41st post town on the Nakasendo, right after Magome and Tsumago. The house was built in the same form as the honjin, the official inns where samurai travellers stayed when this road carried them between Edo and Kyoto.
Fires through the centuries took many of the old houses, but a few kominka remain, still lived in. Kashiwaya is one of them. We're 15 minutes on foot from Nagiso Station.

Not the menu you find in a Japanese restaurant. The food a family in this valley would put on the table for a celebration — a traditional nabe at dinner, ochazuke at breakfast. Quiet, seasonal, careful.
Wagyu to vegan, gluten-free if you need it — tell us when you book and we'll cook around you.

A brewery run by the owner's family makes three beers exclusively for Kashiwaya — you won't find them anywhere else. Alongside them, a small selection of local sake and wine, hand-picked by the master.
The master also runs guided e-bike tours and rentals during the day — the routes only the people who grew up here know. If you want something before check-in or after check-out, ask through the site below.
See Beyond Nakasendo CyclingFour people, one house — keeping it lived-in across four generations.
Fourth-generation owner of Kashiwaya, founded by the Ichikawa family.
He has kept the house alive while moving between overseas, Tokyo, and Nagiso — protecting it through changing times.
Eldest son of Shu Ichikawa.
Based in Tokyo, he runs a hair salon and a brewery, and developed three Kashiwaya-exclusive beers.
Moved from Tokyo in 2015 and renovated three kominka in Nagiso — one of them is Kashiwaya.
He now runs “Yui-an,” an iconic kominka hostel that has become a symbol of Nagiso.
The current operator of Kashiwaya.
After visiting Nagiso many times from Nagoya, he began a dual-base life and apprenticed under Hiroshi Kumagai while working two jobs.
Inspired by a year living in West Virginia, USA, his mission is to recreate that deep “dive into the local” experience here in Nagiso.
“I had the whole second floor to myself — very spacious and lovely. The house is old, so I was afraid it wasn't going to be very nice, but it was clean and I was really pleasantly surprised.”Katerina · Japan
“The house is spectacular — an actual old Japanese house. It is almost magical to walk the rooms, open the traditional sliding doors or enjoy a peaceful dinner in the dining room.”Fabrizio · United Kingdom

No — some Genius Level 2–3 reservations show a “free breakfast” benefit that Booking.com's system displays without any arrangement with us. Kashiwaya has no breakfast-included plans: all meals are optional, paid, and reserved in advance. We're sorry for the confusion this causes.
Be careful — restaurants near us don't keep regular evening hours. The safe plan is to reserve dinner at the inn (up to 3 days ahead) or ask us about same-day meal delivery. We'll gladly check what's open on your dates.
Yes — free Wi-Fi throughout the house.
Kashiwaya itself takes card payments for meals and drinks, but most local restaurants — and all local buses and trains — are cash-only, and can't change notes larger than ¥1,000. Bring a stack of ¥1,000 notes. The nearest ATM is at the 7-Eleven, about 20 minutes on foot.
The shower room, sink and kitchen are shared; toilets are private (the private toilet for second-floor guests is on the first floor — you won't pass through any other guest's area to reach it). There's no bathtub — if you want a proper soak, a day-use natural hot spring is about 15 minutes away by car (closed Wednesdays). We can shuttle you there when our schedule allows, or arrange a taxi.
First-floor guests have a washer-dryer to use. Otherwise there's a coin laundry about 15 minutes' walk away.
Between Magome and Tsumago there's a no-reservation luggage shuttle. Between Nagiso and Nojiri stations we run one ourselves — just ask. For the wider Kiso area (Matsumoto to Nakatsugawa), NLTS and Walk Lite offer luggage transfer with advance booking.
Asian black bears do live in these mountains, but fixed bells along the Magome Pass trail mean no sightings there for about a decade. Bears avoid people and almost always run first; the only real risk is surprising a mother with cubs. If you're worried, we rent bear bells and bear spray.
Easy — sneakers are fine (sandals aren't recommended). In winter, strap-on spikes for icy patches are a good idea; we rent those too.
No pets, and no smoking inside the wooden house — the courtyard is fine. Photos and videos are all OK (sharing them motivates us!). Local residents rise early, so please keep quiet after 21:00.
