Fare facts and planning estimates
You see a price online and want to know if it is real, current and usable.
Planning methods and checks
Log the source and date of every fare
You collected prices from five tabs, and you cannot remember which one was current.
Write down three things next to every fare: where you saw it, the date you saw it and what it covers. A price without a date is a guess. This habit keeps old numbers from slipping into your family budget.
Why do old fares creep in?
Fares change, and an old number looks the same as a new one. The nationwide Japan Rail Pass is a clear example: from 1 October 2026 the ordinary adult pass costs 53,000 yen for 7 days, 84,000 yen for 14 days and 105,000 yen for 21 days 1. A price copied before that date is out of date.
A budget built from several tabs and chats mixes old and new numbers. A log fixes that.
What does a fare log look like?
Keep one row per fare, in a spreadsheet or a notes app.
| What | Price (yen) | Source | Date seen | Covers |
|---|---|---|---|---|
| Example: nationwide rail pass, 7 days | From the operator page. | Operator website. | Date you saw it. | Adult, ordinary, which trains. |
| Example: airport train | From the operator page. | Operator website. | Date you saw it. | One way, one adult. |
The fifth column matters most. A fare for one adult one way is not a fare for a family return.
Which exchange rate do you use?
Use one dated rate for the whole budget. The Bank Negara Malaysia selling rate for yen on 19 October 2026 was RM 2.603 per 100 yen 2. Write the rate and its date at the top of the sheet.
Convert every fare from that single cell, so you update the rate in one place. Our ringgit budget tool does this for you.
How do you keep it current?
Do this each time you open the sheet.
- Re-check any fare older than your own limit, such as two weeks.
- Replace the price and the date together.
- Mark a fare “estimate” if you did not see it on an official page.
- Keep a final check for the week before you pay.
Read fare facts versus planning estimates to separate the two types.
What should you do with promotions?
Treat a promotion like a fare: note the source, the date and the end date. Ask whether it is still current before you rely on it. See is this Japan promotion still current.
What should Malaysian travellers remember?
Keep the yen figure and the ringgit figure side by side, so you know what changed when the rate moves. Share the log with everyone in the group.
If you want a second pair of eyes, send us your log. We check each source and tell you which rows are stale.
If your budget has prices from many places, send us the list. We help you mark which fares are current and which need a fresh check.
Keep planning
Build a ringgit budget with a stated rate
You are watching the ringgit and want a Japan budget that does not change whenever the rate does.
Compare a rail pass with your real journeys
A yes or no verdict on the pass does not help when your route is your own.
Why Japan planning spreadsheets go quietly wrong
Your spreadsheet looks tidy, and you want to know where the hidden mistakes sit.

Questions travellers ask
Why log the date of a fare?
Fares change, and an old number looks the same as a new one. The nationwide Japan Rail Pass rose on 1 October 2026, for example, so a price copied earlier is wrong. A date beside each fare tells you at a glance whether to trust it or check again.
What should a fare log contain?
Five things: what it is, the price in yen, the source, the date you saw it and what it covers. Add the ringgit rate you used and its date. If you can add a link, do. Keep one row per fare so the log is easy to sort.
Which exchange rate should I use?
Use one dated rate for the whole budget, such as the Bank Negara Malaysia selling rate for yen, and note the date. On 19 October 2026 it was RM 2.603 per 100 yen. Change it later in one place, and the budget updates together.
