All Japan, one pass. From Hokkaido to Kyushu, Japan Rail Pass covers all areas of Japan. Once you arrive in Tokyo Narita International Airport, the convenient Narita Express (N’EX) is available to take you to the heart of Tokyo! Hokkaido, Nikko, Tokyo, Hakone, Takayama, Nagoya, Osaka, Kyoto, Hiroshima, Miyajima, Nagasaki… any city you name is reachable with this pass.
For example, cross the country from the south to the north, hunting cherry blossom in spring. If you take the tour from the north to the south, you can chase the autumn foliage, leaf peeping in the fall.
You can use the high speed bullet trains (expect Nozomi and Mizuho) that take you to the next destination rapidly and comfortably. You can choose the duration of pass validity from 7 days, 14 days and 21 days, depending on your travel plan.
