Hi. I want to go to Osaka via Narita. My interested places to go at Osaka is: Aquarium Osaka Kaiyukan, Osaka Castle, Dotonbori dan Shinsaibashi.
Could you give me a recommendation for me about the best area to stay at Osaka (for easily going to my interested places), the route from Narita to Osaka? Do JR Pass valid for all entire transportation?
Thanks before.
Hary Gunawan
