Planning on 2 weeks in Japan next summer - am well aware it is horribly hot but school holidays don’t care! Question is when and where to go - we initially thought as early as poss (can go from 5th June all the way through to beginning of August) and do Tokyo-Kyoto-Osaka obvious route but now I’m wondering considering the heat and that we quite enjoy getting off the beaten track whether we should t do Tokyo then head more north? Any preliminary thoughts?
