I know they can be taken by the Kombini machines but I would like to take them now before I get to Japan. . But the problem is that the websites ask me for a Japanese address and a Japanese number like Ticket.co. jp , how can I do it when I come just to be a tourist?
Buying them before coming to Japan is maybe not possible. Some websites also don't accept foreign credit cards.....heavily depends on which service is used to sell the tickets.
