• Safety - Yeah, you can roam around at night without getting shot. But this place is built on one massive tectonic plate and the massive skyscrapers, the underground subways, and tight conditions make it perilous with the chances of earthquakes and fires. Also, the taxi drivers are quite homicidal. Two of my friends were hit by careless taxi drivers and I even saw one guy do a hit-n-run in Ginza. For foreigners these days, it seems that the government increasingly is taking measures to put them under tight wraps. For what? A few rapes that get overblown by the media and having old women crying out, "It's getting more dangerous here!" You have so little privileges living here as a foreigner that the minute you screw up, that's it. All that hard work goes out the window. Not to mention all the friggin' stairs here. I've slipped on my ass because this place is architecturally unsafe several times. It isn't uncommon to see people with eye patches and fucked up legs hobbling down the street. Makes you wonder. Thing is that everywhere is dangerous, you just gotta be smart how you live. Even a stereotypically safe spot like Japan can be dangerous.
  
• The trains....my problem is that there aren't enough of them and they rudely just leave people stranded. Going home on the last train and suddenly some fuck decides that life sucks? Yeah, it's not your problem, not the train owners' problems, not the conductor's problem. Your ass is stranded.
• Decadent drinking. Sure it's fun, but you can only do this every so often. I've seen and been through horror stories of debauchery. Drinking is completely endorsed because it's a stress relief and allows people to vent, which implies a continuous pacification of the people here. But I've heard that quite a few people have liver disease. You're going to hurt yourself in the long run being stupid like this.
• Sex industry. It's dead here. The government is slowly killing it. Instead, it just becomes higher price, more exclusive, and more underground. And it definitely isn't for the foreign guys (but if you're a woman, you can work in it to satisfy those sick, older gentlemen's fantasies!)
• Akihabara's geek fetishes. It's dead. Taken over by the Yak because they couldn't get their cut on the first try.
• Healthy food. Noodles, rice, beer? High carbs. Lots of salt? High sodium diets and high blood pressure lifestyles. Fresh fruits and vegetables are far too expensive, so people are left with unhealthy bento or instant, which pretty much are not much different than fast food. The only reason why Japanese are not obese like Americans is not because the food is healthier. It's because people here can't afford anything, buy the minimal amounts, and the portions are forcibly smaller. I ate healthier in LA and only now do I regrettably realize it.
• Late night clubs. Waste more money getting dumber. Unless you're hot, you're going to end up like that girl from Babel.
