I'm going to try to travel to Osaka and then back to Tokyo. One week Tokyo maybe 2 weeks Osaka. I'm consider a JR pass. I'm not planning on doing much sight seeing. Would it be worth it to get a JR pass for the week that I would travel from Tokyo to Osaka then from Osaka to Tokyo? Is anyone familiar with the price rages to and from both places? Any Advice Would Be Super Appriciated!!!
