So easy peasy, feels like a rich person who gets in and gets out from Shinkansen. Yes, don’t you worry because it is worth every penny. Buy in your original country, receive the purchase ticket, and when landing in Japan, go directly to the Tourist Information Office. Show your purchase ticket and the officer will replace it with a JR Pass Ticket. This JR Ticket will only be issued once, no reprint, no reissue. If it’s lost or stolen, they will not guarantee a reprint again, so please be careful. It can be used for all JR lines and Hokuriku Shinkansen.
