If you’re planning to do some travelling around by shinkansen (bullet-train) while you’re in Japan, you’d be a few steps ahead by purchasing a JR Pass before you travel.
Granted, at $362 per adult for a 7-day pass, it sounds like a hefty price to stump up in one go, but a few one way fares on shinkansen will make the pass seem like a bargain. F
or your money, you’ll get to experience unlimited travel throughout the country on Japan Rail local and express train services which also includes tickets for most of the shinkansen (bullet trains). From 8 March 2017 the JR Pass will be available for purchase within Japan from selected JR train stations. But it’s still cheaper to buy the Pass before you arrive in Japan, so plan ahead.
