I was reading this artice at Japan Times and found it to be very interesting. It answers the question of "How safe is Japan?" in some details.
I will post some of that article here and the rest is here.
In Japan, paper advertisements hang from the ceilings of train cars. In how many other countries would that be a viable advertising option? Certainly not in my hometown of Melbourne. Back in Australia, the majority of those ads would not survive any given Saturday night.
The buttons that train guards push to play those pre-departure jingles: They are fully exposed! Anyone can walk up and push them. And yet nobody does. They would back home in Melbourne.
The fire extinguishers frequently found sitting out by the sidewalk: No one rolls them down the hill at 3 a.m. Amazing!
Fish tanks that are less than fully secured: Oh my! Back home, the occupants of those tanks would greet the Sunday sunrise floating on their backs in a murky goo.
Valuables: When you lose your wallet in Japan, chances are you'll get it back — cash intact and cards untouched.
Salarymen asleep on the train: They are woken at the terminus with a sympathetic prod by railway staff. Inevitably, the bag containing both laptop and wallet is still resting on the overhead rack.
The last train: Hundreds of drunken people sardined into carriages and not a hint of aggression. Back home, guys would be squaring off on every second platform.
Violent crime: The average victim of violent crime in Japan is attacked by someone they know. Random violence is rare. Perhaps this explains why it is so common to see solitary girls and women wandering home on narrow, dimly lit streets — even in the wee hours in the entertainment areas of big cities.
Police apprehension: It has become apparent in the last couple of years that the average member of the Japanese constabulary is not exactly fleet of foot. Could the extraordinary number of wanted criminals who simply walk into police boxes and give themselves up be one of the reasons why?
The incarceration rate: The prison population of Japan tends to hover around the 60 out of 100,000 mark. For most Western nations it is at least twice that number. For America, more than 700.
Eeeeh so here I am, finally achieving my dream of visiting Japan. Not just that, but I am living there while studying in the absolute best university in Asia, The University of Tokyo. First I studied Masters in Electronics Engineering, and now I am going through PhD in Electrical & Electronics Engineering.
