Hi, I'll be traveling in Japan for two weeks and I wasn't sure if I would benefit from purchasing a JR pass. I'll be entering and leaving Japan from Narita airport. While in tokyo, I expect to take the rail a lot for traveling.
Day 1-4: Tokyo
Day 5: Kusatsu
Day 6-7: Tokyo
Day 8: Kamakura
Day 8-11: Kyoto
Day 11-14: Osaka
Thank you!
