On an upcoming trip we may need to move from one hotel to another (Conrad Tokyo to Park Hyatt Tokyo).

Do the luggage services (takkyubin) offer same day delivery from one Tokyo hotel to another?

Yes, within Metropolitan Tokyo area there are such services, but not all takkyubin services have same day delivery service especially if it is suitcase and not a box with less dimensions than specified.

However, such service is very expensive. Next day delivery takkyubin is very reasonable in Japan. But same day luggage delivery is very expensive and such service is only available at large city like Tokyo and not nation wide service. Last time I looked up such service in Tokyo it was cheaper to do it on my own using taxi.

If you want to use such service ask at the hotel. Especially at Conrad Tokyo I shipped boxes using takkyubin before, the hotel handled pretty much everything. They brought boxes and forms to my room. Once I packed and filled the form, just call and staff was at my room in few minutes. The staff had rate chart and could tell me exact charge for takkyubin and took boxes from the room. Takkyubin was charged to my room.

You're right, a taxi might be cheaper.

Thanks for the helpful information!

For comparison, CY Ginza to Tokyo Hilton is pretty close to the distance of the Conrad to Park Hyatt and ran ~JPY3500 or so by taxi.

I was just going to check the taxi fare between the Conrad and Park Hyatt...thanks for that information!
