I will be in Japan for 8 weeks on a work visa. My wife will be with me on a tourist visa. We are US citizens and will always be traveling together. My understanding is that she is eligible for a Japan Rail Pass but I am not. Is this correct? Am I eligible for any of the regional passes? Does it make any sense for her to have one type of pass and me another? Finally, should we just wait until we are in Japan to buy any passes. I know there is a savings to buying the Japan Rail Pass overseas, but given our uncertainty should we wait? Thanks.
