This time I'm going back to Japan but I'm not going to stay within same city what is Tokyo where friend and my home locates. We are planning to go if we have time to go in all of these; Niigata, Tokyo, Osaka, Kyoto, Nagoya, Hiroshima, Chiba, Yokohama and maybe somewhere else if we feel like it. We bought 21 days JR Pass.
We are living most part of our trip in Kunitachi. We got big room for us. Only sad thing is that it takes around 30 mins to get from there to Shinjuku + walking to train station.
