Is Japan as safe as people though?

'What make u think of coming to Japan?'... respond to this, one of my friend answered, 'Japan has one of the safest city in the world which is Tokyo. So i think that, I will have a good safe life studying here'...quite absurd to me...

So, i m just wondering, is Japan that safe? Is Japan's crime rate is low, the public security is good and is Tokyo a safe place for u to hang out alone at the street at the middle of the night? If its yes, how come these few days, i have been bothered with the news of murderer, suicide and juvenile cases??? Then, how come lots of people that i knew, have the idea that Tokyo is a safe place??
em...so now in short I would like to reveal the true colour of Japan....

Recently, there is a breaking news of the murderer of a Electric Engineering Professor of the Falculty of Science and Enginering of Chuo University.(as a matter of fact, this is one of the uni i m applying and praying hard to be accepted in). The professor Hajime Takakubo, 45 being stabbed 60 times around the chest, back, and, hand. The decease died from bood loss and damage to his heart ,lungs and aorta according to the newas paper here. The murderer is suspected to be man of 30 and was seen wearing black cloth and fled from the crime scene.

Last year, there was a mass muderer in Akihabara, where around 11 were dead and leaving a number of padestrian injured. It happened when a man who is low self-esteem, start blaming the community for him not having a life partner(balmming that the Japanese girls only emphasise on the look of opposite sex, and the guy himself is not that goodlooking) , he drove a lorry, which run over a few pedestrian who were crossing the road, and later jump out of the car with a knife and start clashing who ever were on this way... this is mentally crazy!!! Another one was in the train station where a man with a knife, start slashing the public without reasons, and then fled into the mall..huh...

End of last year, there was an accident where a high school boy killed his biological father whould any particular reason. He was writting stuff in his blog saying that 'I dont not love my dad but i just have the feeling of killing'..... extra mental!! There are more ...just that i can't remember...

So guys, is Japan that safe? Japan is just as same as other countries, with its pros and cons, but with the idea that Tokyo is one of the safest city is tottaly wrong. However, dont freak out, I m believe that with luck and the spiritual protection, you can have a nice safe holidays here.

PS: i m not here to talk all the negatif stuff about Japan k..just that these stuffs are a nuisance to me, so i was like want to talk about all this..Apart of all have happened, I still love Japan!!!
