Are you planning to head for Kyoto, Osaka or farther west from Tokyo? JR PASS allows so many overseas tourists to travel around Japan by train and Shinkansen bullet train, which is pretty good value.
Japan Railway announced that the prices of their multiple use pass for overseas tourists, JR PASS is revised on October 1.
For example, a 7-day PASS for Ordinary Car currently costs ¥29,656-/adult. The revised price goes to ¥50,000-. It costs ¥26,640- for a return trip between Tokyo and Kyoto by Shinkansen HIKARI. It works well if you go with Shinkansen at least 4 times and take JR regular trains multiple times.
