We are flying into Haneda at 10pm, so wouldn't be able to activate the JR Pass in time and will have to get into Tokyo another way, right? Do you know how?
We're spending a few days in Tokyo and traveling to Kyoto then Osaka and finally flying out of KAI. I think I can get individual rail tickets for less but friends have told me the JR Pass very convenient to have while we're in Tokyo to use on the JR Yamamote line? We're staying in either Shinagawa or Harajuku.
