Toilets at Mt Fuji's summit cost ¥300 per visit, mountain hut bottled water is ¥500, and a summit-certificate amulet is ¥1,500. All cash only. Above 3,000 m, credit cards and electronic money simply do not work — you'll be stuck unless you carry lots of 100-yen coins and ¥1,000 notes. Per person for a 1–2 night climb, plan for ¥15,000–25,000 in cash. Here's the full breakdown and a smart currency strategy.
Why Mt Fuji is cash only
Connectivity constraints above 3,000 m
- Mobile signal drops out in many spots
- Card terminals need network connectivity to function
- The summit and 8th station can't reliably operate a payment system even if installed
Mountain hut economics
- Helicopter supply runs make goods expensive (altitude = price)
- Thin-margin operations can't absorb 3–5% card fees
- Cash-only has been the operating norm for 100+ years
Environmental fees / toilet contributions
- Summit and 8th-station toilets use "chip-style" (drop-in) payments
- Funds installation, removal, and waste processing
- Card terminals are infrastructurally infeasible

- Toilets × 5 (7th station and above)
- Vending machines (some, due to change-making issues)
- Donations and small items
500-yen coins: ~5 pieces
- Vending water × 5 (7th station onwards)
¥1,000 notes: 10+ pieces
- Mountain hut overnight (cash ¥9,000–¥15,000)
