Prior to our departure, we bought a 7 day Shinkansen (bullet train) pass. Definitely $300 well spent. It took us to Hiroshima and Miyajima then couple days at Osaka with an average speed of 320 km/h. Off to Kyoto for one day then back to Tokyo. Day trip to Yokohama, to a relaxing Karuizawa and Sendai. The ride was so comfortable!
Below are photos taken from Hiroshima and Miyajima.
