We are from Australia and will be visiting Japan next April.
We read about the Seishun 18 ticket which seems to be much cheaper than JR pass for travelling around. I understand that it is only available for some period of time.
My question is, we will be arriving on 4th April 2016, which is after the date where the ticket is available for sale (some website mentioned that ticket only available for sale until 31 March). Is there a way to buy ticket from outside Japan? Or is there anyway to pre-purchase the ticket before hand and pick it up from the ticket office once we are in Japan?
Thank you in advance,
