We're going to Japan in July. We will be in Tokyo Kyoto and Hiroshima and so on to Korea? What is best to do? First Tokyo then take a train to Hiroshima and back to Kyoto and take flight from Osaka to Seoul? Or travel the same day we get to Tokyo, take the train to Hiroshima, back to Kyto and then a few days Tokyo and fly from Tokyo to Seoul. Is rail pass the best buying or individual tickets? Is there any possibility from Hiroshima to Seoul instead to return to Tokyo.
