We're planning on going to Japan for 7 days, arrive Osaka May 15 stay for 4 days and stay in Tokyo for 2 days and then back to Osaka to fly to the Philippines. While in Osaka we plan to take the trains to Kyoto, Nara. Is it worth to buy the 7 day JR rail pass? Any suggestions where to take day trips from Osaka with the JR pass? How do we get to Kansai airport with the train? Thanks!
