Identify the existing arrangement first
Give the business name, booking name, reference, and current date or service. If you have more than one reservation with the same business, identify the one you mean and say which should stay unchanged. Then describe the proposed change in its own sentence.
Be precise about the scope: moving one night is different from moving the whole stay; dropping one passenger is different from cancelling the entire group. Mention what should remain the same, such as the room type or the return transfer, when that distinction matters.
Choose between exploring and instructing
The condition belongs in the outgoing request, not only in a private note. ‘If it is free’ changes what you are authorizing. If you are still comparing alternatives, ask for information before asking the business to release anything.
- Exploring: ‘Please check availability and explain any price difference. Keep the current reservation unchanged for now.’
- Ready to proceed within a condition: ‘Please request the date change if there is no additional charge. If a charge applies, tell me before proceeding.’
- Already decided: name the exact change you want the business to make and the terms you have accepted.
A message you can adapt
For reservation [reference] under [name], currently [dates/service], could you check whether [proposed change] is possible? Please explain any price difference, fee, and deadline to decide. Keep the current reservation unchanged while I review the options. The [other reservation or part of the trip] should remain as it is.
This is an illustrative inquiry, not a cancellation or change instruction. Remove the last sentence if there is no other arrangement to distinguish.
Keep the answer attached to the choice
A useful reply tells you whether the requested change is available, what it would cost, and how to confirm it. If the business offers an alternative, keep its date, price, conditions, and decision deadline together. An answer such as ‘possible’ leaves the terms unresolved.
For ryokan stays, the Japan Tourism Agency’s guide highlights cancellation fees and directs travelers to check payment details with the property or booking site. Use the terms for your actual reservation rather than applying a general rule to it.

Close the loop after your decision
When you accept an option, refer to that option explicitly: ‘Please request the move to [date] with the [stated amount] difference.’ If you decline, say that the existing reservation should remain. Ask the business or booking channel how the change is completed if the reply leaves that unclear.
Keep the final confirmation separate from the earlier offer. Check that it reflects the right booking, dates, and agreed conditions. If no final confirmation has arrived, the change is still awaiting confirmation; do not build the rest of your plan around an assumption.
How Broc fits in
You can explain your goal and your limits privately to Broc. It helps communicate with a participating business and brings the reply back. The business or booking channel makes the actual change, and you make the decision on new costs or commitments. Saying ‘ask whether it is possible’ should remain an inquiry all the way through.
