How to build a realistic Japan trip budget

Last checked 2026-10-21
The most reliable Japan budget splits costs into things you can look up exactly and things you can only estimate.
- Look up exactly: long-distance trains (see our fare table) and your actual hotel quotes for your dates.
- Estimate: food, local transport and activities. Pick a daily figure per person and be honest about your habits.
- Convert once: use one exchange rate for everything. We use ¥158.13 per $1 (ECB, 2026-10-20); your card will add its own margin.
- Add a buffer: leave room for price changes and surprises.
Then plug it all into the budget calculator.
Prices change. Confirm with the operator before booking.
