I'm heading to Japan for about 3-4 weeks in september starting at Osaka then going south to Hiroshima and then in the other direction to Kyoto, Nara, Tokyo finishing back up in Osaka. Was thinking about getting JR 21day railpass and activating it on my way out of Osaka. Going to spend about a week or more in Tokyo depending on how much i like it and a couple of days at the other destinations. Does this sound like the best way to get a broad picture of Japan in only a few weeks? I'll probably take in some day tours as well but is there anything i'm missing that i must see?
Should i book accomodation in advance for hostels or is it ok to book a few days prior? Basically i want to pick up and move whenever i get the urge.
Also does anyone have any advice with regards to going to J-league games? Are the tickets pricy? Are the grounds accessable?
Thanks for your help!
