The Rental "Start Date" is the date you pick up and begin use of the item. The package will be delivered by the night before the "Start date" you choose. The time of delivery cannot be predetermined.

Rental "Return Date" is the date you must post the return package in a post box in Japan. Early returns are welcome. Late charges will be applied if you don't post the return package on the designated return date. If you wish to use the item longer, please extend the rental period before the return date.

We check both the postmark and the date usage history and will contact you if receipt is taking longer than expected, but there will be no additional charges as long return package is posted by the correct date. We will notify you by email once the items are back with us.
Please pick one from the packages that are available. If none of the packages suit the period you need, you can either extend the rental after purchasing or purchase a longer package and return it early.

For example, if you need to rent for 8 days, you can buy 7 days package now and extend 1 day, or buy a 10 day package.

NOTE: Depending on the period you need, it could be cheaper to get a longer package. For example, if you need it for 9 days, it is cheaper to get the 10 day package rather than the 7 days and extend it for 2 days. Please compare before purchase.
