First visit

Your first session, graded easy.

We grade climbs from V0 up. Your first visit is the easiest problem in the gym — three moves, no falls.

V0

Show up

No booking needed. Bring socks and clothes you can move in — we handle everything else, including a 10-minute safety intro.

Registration ¥550 (once, ever)
V1

Gear up

Rental shoes and chalk at the front desk. Our staff will size you and point you to the yellow circuit — the friendliest holds in the building.

Shoes + chalk ¥550
V2

Climb

Follow one color from start hold to top hold. That's the whole sport. When your forearms give out, the café bench and cold barley tea are free.

Day pass from ¥2,200

Total first visit: ¥3,300 — pass, rental, and lifetime registration. Weekends add ¥330 to the day pass.

The walls

Something for every grip strength.

Four zones, reset in rotation every two weeks — so there's always a fresh project and always something you can finish today.

Neither do we. Walk in any day — your first problem is waiting.
