Why here
Wide open plateau with mountain views, low light pollution — and Manza Onsen sulphur springs fifteen minutes away.
Hi, I'm Kenji. With my wife and a few stubborn friends, I'm bringing an old resthouse back as a place to work and camp — fiber desk by day, tent and fire at night. (Oat-milk latte: still working on it.)
You drove three hours to get here. The sunset is around 18:30. Manza Onsen is fifteen minutes away. Day passes exist — one night is fine; two is when your body usually starts to settle.
Tokyo coworking day-passes run ¥3,300 — eight hours at a desk, then home. Glamping in Gunma and Nagano averages ¥15,000–¥35,000 per person per night — one night, full service, no desk. Coliving in Japan runs $1,300–2,500/month in the city. Tsumagoi is from ¥7,500/night solo (¥11,500 for 2 adults) all-in at 1,444m: fiber coworking, heated showers, shared kitchen, gym, heated lounge — you sleep in a tent. Day passes ¥2,400 (kitchen included). Seven nights −15% on the same pass (solo 7N ≈ ¥44,600), scaling to −28% at 30+ nights.
This used to be a roadside resthouse on the Manza Highway — the kind of place where travellers pulled over for the view, an ice cream, and a ring of the 愛妻の鐘, the "Bell of the Beloved Wife." Then it sat abandoned for more than five years. I started renting it in autumn 2025. Renovating took the best part of a year, mostly because the winters up here simply tell you to stop. My wife, a few stubborn friends and I camped on the abandoned ranch through that first winter — no heating, just a kerosene stove, no working shower, an unusable kitchen. We survived. Then we double-glazed the whole building, and now the indoors stays warmer than the outside. Small victories.
I built Tsumagoi for people who want to ship code in silence and eat pizza under stars — not for families wanting a playground or hotel turndown. Day passes exist, but this place is three hours from Tokyo; you'll miss the sunset over Asama-Shirane, the plateau going quiet at 22:00, and Manza Onsen fifteen minutes away if you leave before dark. One night is bookable; two nights is when the mountain usually starts to work. Pack a layer, a sleeping bag, your laptop.
Elevation
1,444m. Quiet nights, far from streetlights. Nights drop to 10°C even in summer.
Kitchen table
Tsumagoi means “thinking of someone you love.” A small highland kitchen-table community — not a co-living dorm or hotel bar.
Office
Fiber internet, heated coworking office, IoT-managed site. Tokyo day-passes run ¥3,300 for 8 hours; here ¥2,400 (kitchen included). Overnight from ¥7,500 (solo) buys desk + tent site + gym + kitchen + shower for 24 hours.
