I'll be traveling Japan from March 23rd to April 13th, a total of 22 days. I'll be landing in Fukuoka to spend a night and then go to Osaka and Tokyo. I'll then be back to Kyushu on April 3rd and spend rest of my time there. I'll be getting a regular JR Pass, but does that cover my travel needs in Kyushu or should I get the Kyushu pass also? I might change my travel plans in Kyushu a little depending on the suggestion.
