We visited the Japan Rail Cafe in December 2016, and had return a few more times ever since!
This place aims to be a one-stop station, where customers can enjoy not only food and drinks (with monthly specials focusing on selected regions in Japan), but also do some quick shopping at the small retail section, as well as obtain travel information and purchase Japan Rail Pass (JR Pass) at the Rail Pass Counter.
It was particularly interesting to revisit, because of the monthly changes (Dec 2016 was on the Tohoku region), and we also enjoyed reading about the various Japan regions in the newsletter, that also served as a menu.
Free WiFi was also available, so we could do some quick browsing on the spot whenever we found something of interest, and wanted to find out more.
