You will need to do the same at the drop-off station. Your pass will be returned to you, so don't forget to take it out.
The dates of use do not have to be consecutive.
For example, in the case of a 3days pass, if your validity period is from 2023/01/01 to 2023/01/31
You can use three consecutive days like 01/12,13,14 or non-consecutive days like 01/12,15,20.
If you leave Japan once, you can use it as long as the number of days remain within the validity period.
If the expiration date has passed, the pass cannot be used.
One day is counted as the duration from the first train to the last train in a day.(not for 24 hours from the first use)
