Hi - I'm traveling to Japan for the first time in May. I will be in Japan for 8 days. After reading blogs, I'm a little confused about my eligibility to purchase the JR Pass. Reading online it says that the JR pass is only valid for those traveling between 15 and 90 days. Because my travel is less than 15 days, does this mean I'm not eligible to purchase the pass? FYI I am a resident of the United States.
Thanks!
