This is convenient for traveling around Tokyo!
But only subways can be used.
1-day, 2-day and 3-day tickets are available
It would be more convenient to buy in advance.
If you would like to prepare before you arrive, you can buy the ticket online on Klook and pick it up at the station with your QR code (affiliate link).
Try it!
