50guests
Free-field cap on an open day — guests per day
40guests

The limit is what the mountain's septic system can handle. Paying more does not raise it. We host one group, properly.

Charter the ranch — any day of the week. Full-venue events are our headline offering: offsites, retreats, filming, weddings, private celebrations.

  • Seven days a week. Tuesday and Wednesday are charter-only days, with no general camping.
  • Thursday to Monday, any date without a public booking is yours.
  • Once your event is confirmed, the ranch closes to all other guests — your group, a host on site, nothing else on the mountain.
  • Requests up to 12 months ahead. Events always take the calendar first.

Before you book

  • Facilities included · AV is a 65" TV

    Charter includes equipment and shared facilities (kitchen, gym, office, showers, BBQ areas). AV is a 65-inch TV with HDMI plus a small backup projector — no large whiteboards, so plan sessions around the screen or the outdoors. You can't sleep in the main building; indoor space (up to 30) is for gatherings, and overnight stays are in tents at the campsite. Ask us about filming or live streaming.

  • Weekend & seasonal surcharges

    Fri, Sat, Sun and holiday eves: +¥30,000. July–September (summer) and October (autumn foliage): +¥30,000. Both apply per day or per night. Extending a day charter to 23:00: +¥30,000. Other extensions (early load-in / late checkout): ¥20,000 per hour, arranged in advance.

  • Production days & midweek

    Production Day (filming or content): flat ¥150,000, crew up to 30. Midweek Basecamp (Tue–Wed, daytime): ¥45,000 per day, contracted organisations only. Production and commercial-event charters carry a 10% operations & management fee on the venue price.

  • Opening season

    Companies and groups book the same flat bands. For the opening season there are three Founding Charters: in exchange for letting us publish the story, you get a custom sticker run and ¥20,000 in courtesies (not a discount on the rate).

  • Bring your own meals

    No cooked meals — cook in the shared kitchen or bring food. Basic seasoning on hand; bring favourites. Alcohol not sold on-site. Minimart: ice, snacks, cup noodles, microwave meals, drinks (pay-as-you-go).

  • Invoice & qualified invoice

    Invoice billing (請求書払い) available · Qualified invoice issuer 登録番号 T5011003021894

    Tsumagoi-wari — thank you, always: residents of Tsumagoi Village get 20% off Open-Day camping and standard event bookings. Address verified at check-in.

OFFSITE BY DAY · ONSEN BY NIGHT

Run the day here — sleep in an onsen town

Charter the mountain for the day — sessions in the hall, breakouts on the field, fire circle at dusk — then drive down to a hot-spring hotel for dinner, baths and beds. Manza Onsen is about 10 minutes up the Manza Highway (allow ~15 in snow); Kusatsu Onsen is roughly 50–60 minutes via Mihara (the year-round route).

Manza Onsen

Manza Onsen

~10–15 min via the Manza Highway (15 in snow)

Kusatsu Onsen

Kusatsu Onsen

~50–60 min via Mihara (year-round route, estimate)

Drive times: Manza ~10 min per the Tsumagoi tourism association, ~15 min when the road is snow-covered; Kusatsu 50–60 min is an estimate via the year-round Mihara route. The direct R292 route past Manza is seasonal and can close at short notice on volcanic-alert changes — plan Kusatsu transfers via Mihara. The Manza Highway is a toll road (cash only, no ETC).

A deposit of 50% of the estimated total (minimum ¥50,000) confirms your date. Until the deposit is paid, dates are held tentatively for 7 days.

The balance is invoiced and due 30 days before the event day (bank transfer or card).

One free date change (within 6 months) if requested 30+ days before the event. Changes inside 30 days are treated as a cancellation. If you cancel after a date change, cancellation fees are calculated against the original event date.

If we close the venue due to weather warnings or disasters, all amounts paid are refunded in full (consequential costs such as travel or equipment are not covered). Ordinary rain is not a cancellation event.

Open event

New-moon stargazing night

Not a charter: a night anyone can join with a ticket.

  1. New-moon stargazing night

    · Ticket ¥1,000

    19:00〜21:30

    • We provide hot drinks and a fire pit to keep warm.
    • Everyone gets a disposable hand warmer and a printed star chart for the night.
    • The hosts are stargazing beginners. There is no expert commentary.
    • Install a free star-map app (Stellarium Mobile, Star Walk 2 or similar) before you come: hold your phone up to the sky and it names the constellations.
    • The field is unlit at night. There are no homes or buildings within 7 km.
    • Parking for 100+ cars, and the toilets are open to everyone attending.
    Book on Peatix
    Event details

Tickets are sold on Peatix and Luma, not on this site.

No neighbors for 7 km.

Open Days go quiet at 22:00. A full-venue charter does not.

Wi-Fi on the field and in the building

Wi-Fi reaches the field and the building. Join a call from the tent or a camp chair.

No quiet hours on charter days

Amps, karaoke, live sets, fire-circle talks past midnight — no neighbors for 7 km means nobody to disturb. (Open Days keep quiet hours 22:00–08:00.)

Handheld fireworks welcome

Toy fireworks (がん具煙火) need no permit, and we welcome them. Handheld and fountain types only (no launched/rocket types), designated gravel area, bucket of water, embers to the ash cans.

BYO tent sauna welcome

Bring your own tent sauna, stove, and cold-plunge tub — a field, water access, and fire rules are the whole product. We never provide or operate a sauna (that would need a Public Bath House Act permit).

An unlit field at night

The field is unlit at night, at 1,444 m with no homes or buildings within 7 km. Schedule around new moons; the Perseids (mid-August) are the flagship star-party window.

Drone-friendly

Outside any DID (populated-area) zone — filming crews and drone schools hunt for legal practice fields like this. Pilot is responsible for Aviation Act compliance (registration, Remote ID, line-of-sight, under 150 m, 30 m clear of people and property; flying at night or over the event crowd needs separate approval).

Pets welcome

All camp sites are pet-friendly — well-behaved dogs welcome, leash in shared areas.

Communities, this is your field

Events this mountain is good at

Sauna meets (BYOS)

Bring-Your-Own-Sauna field day: tent-sauna owners show off their rigs, the mountain provides water, space, and fire rules.

Water access + open field

Car & moto meets

Jimny convoys, rooftop-tent and overlanding crews, camper vans, touring riders — the host drives a JB74 himself. Convoy in (4WD only, at your own risk), pitch on the field; where the vehicles park is set in the charter quote. No closing time.

100+ parking

Star parties & astrophotography

Telescope clubs and astro-photo communities schedule around new-moon nights — hand them an unlit field far from town lights, with indoor warm-up space.

Unlit at night

Band & orchestra camps (音楽合宿)

Rehearsal space in Tokyo is expensive and time-boxed. Here a group gets a carpeted indoor hall plus outdoor volume freedom for a whole weekend — midweek charters fit school and amateur ensembles perfectly.

Carpeted indoor hall

LAN parties, game jams & dev sprints

Fiber at 1,444 m, a table for every laptop, and total isolation — a hackathon venue that sounds made up. Esports bootcamps belong here too.

Fiber + 20+ tables

Cosplay & photo-shoot days

Open fields, mountain backdrops, an unlit field after sunset, and indoor changing space — photography communities book venues by the day.

Fields + indoor space

Corporate sports day (運動会)

A booming corporate-events genre: open field for the games, indoor hall as rain backup, convoy-scale parking. Exactly the spec event buyers search for.

Field + rain backup + parking

Dry & Return — post-event tent drying

What it covers

Rain on event day? Leave the wet tents with their storage bags and we air-dry them in the yard — ¥3,000 per tent, charter bookings only, tent count agreed in advance. You arrange the Yamato return pickup at the venue and sign a damage waiver (免責): we dry, you ship.

"Strategy under the stars"

What it covers

Book your charter around a new moon and end day one on the unlit field after dark — we'll flag meteor-shower windows (Perseids) when you pick dates.
