Why people come up here

  1. Hard to reach. That is why the view is this good.

    1,444 m up, about 10 km by road to the nearest homes. In front of the deck: grassland, then the ridges.

  2. Far away. So you can be loud.

    About 10 km by road to the nearest homes. Laugh as loud as you like until 22:00; on a whole-site charter there are no quiet hours.

  3. No restaurant. So you sit around one fire.

    No restaurant and no staff. You cook in the shared kitchen and bring it to the brick fire pit on the deck.

  4. Cold. That is why warmth feels this good.

    Winter nights go below zero. All-in Camp guests: The Kotatsu Lounge is open 24 hours. You sleep in your own car or a tent.

  5. No marked pitches. So you pitch wherever you like.

    One open field with no marked pitches, and at most 5 groups a night, so the next tent is never too close.

  6. Dark at night. So you look up.

    The field has no lights at night. On a clear night, the stars are sharp.

NextMorning

Morning meeting: the sunrise.

Check-in is Thursday to Monday; to arrive on Tue/Wed, ask us on LINE.

Real camp on a real mountain: you pitch, you cook, and the sky goes properly dark. We'll help you prepare — not do it for you.

Close to the sky, so the reception from the higher authorities is excellent.

Sennin Kenji's story

A dream, still in the making.

  1. It's a place I've dreamed of since I was a kid.

  2. For years, on the side, a little at a time.

  3. I started this place on my company's IT work, my savings and my salary.

  4. I built almost all the furniture here myself.

  5. Grass cutting, the septic tank: I learned them all up here.

  6. People think I'm the part-timer. No: I'm the owner. The hermit.

  7. It's still being built. Come and see it grow.

Sennin Kenji: an illustrated hermit with glasses, a staff and a gourd
Not the part-timer. Sennin Kenji

Words guests left in their Google reviews, as they wrote them. They wrote in Japanese; the English is our translation.

  • Even on my first camping trip, I felt at ease! The panoramic view and the quiet were so soothing that I want to come back. And there is an onsen nearby you can visit for the day!

  • A place where you can feel overwhelming nature you will never find in Tokyo. Besides the nature, there is a warm-hearted owner, a lake for fishing, onsen and many more spots. I recommend visiting at least once!

  • With no buildings around, we could enjoy a place full of nature. Wi-Fi, power outlets and the rest are all there, so one person or a big group can get by without any trouble. Next time I would like to stay longer: a place I would like to enjoy while working.

Common questions

    • All-in Camp ¥7,200 first adult/night
    • Field only ¥5,200 first adult/night

    It's a mountain workplace, not a pitch for rent.

    • At 1,444 m the Kotatsu Lounge has fibre desks (100Mbps fiber) and, in the cold months, a kotatsu.
    • Indoors is warmed by two Daikin industrial heat pumps (air conditioners).
    • There is no kerosene heater inside, so no fuel smell and no combustion fumes indoors.
    • There is a shared kitchen and hot showers.
    Read the restShow less
    • You sleep in your own car or a tent.
    • So the price is for the time you spend and work here, not for a plot.
    • The All-in Camp is ¥7,200/night for the first adult and ¥4,200 for each additional adult, with the Kotatsu Lounge open 24 hours and unlimited hot showers: Warm all night, every night.
    • Field only is ¥5,200/night for the first adult and ¥2,200 for each additional adult with the field, shared kitchen, toilets and parking (the gym is on every plan).
    • Both share the washlet toilets with warm-water bidet seats and the roofed deck terrace with its brick fire pit, and there are yoga mats on site.

  2. This is a real former pasture: gently sloped, leveled a little more every season.

    • Blue ground sheets (ブルーシート) are laid in parts of the field so grass doesn’t grow under a tent — pitch on one if you want a flat base that is ready to go, or anywhere else on the field you like.
    • Bring a thick sleeping mat if you want extra comfort, and if you feel a lean, pitch with your head uphill.
