> My reply was always a simple one, “The Yakuza and Kabukicho aren’t scary, if you don’t mess with them they don’t mess with you. The Police? Now that’s a different story. Hands down scariest thing in Japan is the Police & the Justice system”.
So he responded to a low-key compliment by insulting the interlocutor's country? If this is representative of how he interacted with people there, I'm not surprised that he was unpopular.
Criticising the police is an exercise in civic bonding in the Anglo-American sphere these days, but I don't think it's much of a thing in Japan (and they tend to be very proud of their public safety climate). Was the author simply unaware of this, did he think that only his own culture's priorities regarding what it is okay to criticise matter, or did he not realise that people tend to identify strongly with at least some aspects of their countries at all? (Certainly, the UK has its own set of holy cows: back when I lived there, I learned of one the hard way after suggesting during a casual conversation that the political system of the UK would have turned out better if it had gone through at least one violent revolution in the past two-or-so centuries as all the other European countries did.)
