Negative Experiences in Japan?

Japan is a great country, with a lot to offer both short-term visitors and tourists as well as people like me, who like the place so much we put down permanent roots. But still, Japan is far from perfect, and there are various sources of stress for gaijin living here, for example (if your language skills are still improving) not being able to talk freely to people or even to read what’s written on some signs, not being able to understand local customs that might be taken for granted by everyone but you, or (if you live in a rural city like I do) having kids occasionally stare at you because you’re different. (I just say hello to them in English.) I’ve lived in Japan for 17 years and have traveled quite extensively throughout most of the country, meeting a lot of people along the way. It has happened, so infrequently it’s almost statistically insignificant, that not every experience I had here was a good one, and not every person I met was 100% happy to be dealing with an overly-exuberant American like myself. Like an old farmer who, when in his cups, asked me why “big America” had to beat up on “little Japan” during the war, or the scary yakuza gangsters I found myself surrounded by when I stupidly stayed at a 24-hour sauna in Kyoto, or the one time I tried to enter a bar in Roppongi and was told politely that they didn’t accept foreign customers. (I should have worn our “No Gaijin” T-shirt.) Whenever I encounter some minor inconvenience I shrug and move on, reciting that useful Japanese mantra shikata ga nai (or more colloquially, sho ga nai), which means “it can’t be helped,” the main way the Japanese maintain their happy, largely confrontation-free society. I know that everyone is human, and for every minor negative experience I may encounter here in Japan, there are a few hundred positive ones. (Thoughts of girls’ phone numbers scrawled onto chopsticks wrappers come to mind, but we don’t go there.) ^_^
