Delivery time in Japan

Hi
I am in Japan now.
If i order a pass now/today will the pass be able to arrive tomorrow (Friday) or the day after tomorrow (Saturday) to our temporary address in Hiroshima which has a mailbox? Is it I shipped from Japan?
We have to leave Hiroshima on Sunday…
What happens if it arrives after we have left? Will we get a refund if the we haven’t exchanged the voucher for a pass?
Best regards Emil
