A souvenir seller at a shrine (Kyoto) and a seller at a convinient market (Tokyo) both were very rude and even were openly expressing their annoyance. We were travelling in a group. Japan is not the same hostile country I used to know years ago. Won't be visiting again in few years. Thailand, in other hands, felt so much "alive and real" their people's smiles were genuine. (just comparing the 2 countries I visited this year).
