Wondering if it's worth getting the 7 day rail pass or not? I've read so many different things and it's all a bit confusing.
I don't know if the JR Pass is for quick train rides or more so regional trains? If so, I figure I'd be better off getting the 7 day pass and using for when we leave Tokyo? Then using whatever there general system is for everyday use when travelling around Tokyo? Itinerary is basically this:
Tokyo > Osaka
(01/09) - Land at Tokyo Narita International Airport, check into hotel in Tokyo, explore Tokyo/Shibuya (02/09) - Explore Tokyo/Akihabara (03/09) - Ueno Zoo & Robot Restaurant (04/09) - Disneyland (05/09) - Check out of hotel in Tokyo, go to Osaka, check into hotel in Osaka then explore (06/09) - Go to Osaka Aquarium Kaiyukan and Nara (07/09) - Universal Studios (08/09) - Hiroshima (09/09) - Check out of hotel, travel back to Tokyo Narita International Airport
