Start with the stay and the new arrival estimate
Use the name on the reservation, the check-in date, and the accommodation’s exact name. Include the booking reference if it helps identify the stay. Write the date in words and make clear that the arrival time is local to the hotel, especially if your journey crosses midnight.
You do not need to explain your entire travel day. A short reason such as a delayed train gives the staff useful context. Distinguish an estimate from a promise: ‘around 9 pm, depending on the connection’ is more useful than a precise time you cannot yet support.
Ask separately about check-in and anything time-sensitive
If your ryokan plan includes dinner, ask about it explicitly. The Japan Tourism Agency explains that ryokan meals commonly have a service window and recommends contacting the property when a delay may cause you to miss it. Permission to check in late does not, by itself, answer the dinner question.

- Can you check in at the estimated arrival time?
- If dinner is included, what happens if you arrive after its service window?
- Is there an entrance, key-collection procedure, or contact method to use after reception closes?
- When should you send another update if your estimate changes?
A message you can adapt
Hello, this is [booking name], staying on [date], reference [reference]. Our train is delayed and we now expect to arrive around [time, hotel local time]. Is check-in possible then? Our plan includes dinner; please also let us know whether dinner will still be available. If arrival is later than expected, how should we contact you?
This is an illustrative template, not a message already sent. Remove details that do not apply. If you do not know your new arrival time, say that and ask what the latest workable arrival would be.
Keep the conditions with the answer
‘Yes, until 10 pm’ is a conditional answer. Keep the time limit beside the permission. If the reply answers check-in but leaves dinner unresolved, follow up on dinner rather than repeating the whole request. If a different arrival time is offered, decide whether you can meet it before treating the arrangement as settled.
When the estimate changes, send one clear update tied to the same stay: ‘The new arrival estimate is 9:45 pm; does the check-in arrangement still work?’ If you need an immediate answer, use the property’s listed contact option rather than relying on an unanswered chat.
What to tell Broc privately
You can explain the situation naturally and identify the participating accommodation. Include useful booking details and say which questions matter most. Keep unrelated confirmation numbers and personal details out of the outgoing request. Broc helps with the communication; the property decides what it can accommodate. A request being sent is not the same as a late arrival being accepted.
