I am debating buying a JR pass for Japan since I am going for about 10 days. I can buy a seven day pass but would it be cheaper to just buy train tickets as I go? I don't want to shell out almost 300 dollars if I don't use it that much. Does the JR pass work for the subways in Tokyo as well? Please anyone with insight, let me know.
My travel dates are from August 2nd-6th in Tokyo. August 6th until 8th in Osaka and the 9th until the 11th in Kyoto and heading back to Tokyo for a night. What would work best for me?
