What's the actual breakdown for $1,500?
| Spending category | Amount | Cash strategy | Wise debit | 3%-FX card |
|---|---|---|---|---|
| Hotels (¥45,000) | $300 | ¥45,000 (cash exchange ~¥0 cost) | ¥45,184 (0.41%) | ¥46,350 (3%) |
| Restaurants (¥35,000) | $230 | ¥35,000 (cash) | ¥35,144 (0.41%) | ¥36,050 (3%) |
| Transit + IC (¥15,000) | $100 | ¥15,000 (cash) | ¥15,062 (0.41%) | ¥15,450 (3%) |
| Shopping (¥30,000) | $200 | ¥30,000 (cash) | ¥30,123 (0.41%) | ¥30,900 (3%) |
| Cash buffer (¥15,000) | $100 | ¥15,000 (best Tokyo shop) | ¥15,062 (Wise + ATM fee) | ¥15,750 (3% + ATM fee) |
| Total | $930 | ¥140,000 | ¥140,575 | ¥144,500 |
For the same ¥140,000 worth of spending:
- Cash strategy: only the in-shop spread cost; about ¥1,500 total spread (best Tokyo shop)
- Wise debit: ¥575 in fees (0.41% × ¥140K)
- 3%-FX card: ¥4,500 in fees (3% × ¥140K)
Net additional cost vs cash: Wise saves ¥925 vs 3%-FX card. Cash + 3%-FX card combo: cash saves ¥3,000 on the cash portion; card costs ¥4,200 on the card portion = ¥1,200 net loss vs Wise.
What's the optimal hybrid strategy?
For most travelers, the hybrid strategy wins:
- Cash for 20% of spending (cash-only situations) — exchange at best Tokyo shop (¥0 spread)
- Wise card for 80% of spending — predictable 0.41% on each transaction
- ¥10,000–¥20,000 cash buffer for emergencies
This combination minimizes total cost while maintaining flexibility.
