i'll be traveling to tokyo in january for 10 days. i'll mostly be in tokyo but i have plans to visit friends in kyoto and osaka as well as a quick trip to yamanashi and/or kawaguchiko to see mt. fuji. considering getting a 7 day pass but not sure which 1 to get.
is it worth spending money on the JR Pass or is there a regional 1 that would better suit my needs?
