Well, unlike South Korean media, Japanese traditional media never reports negative side of other country.
Let me give you an example. Joji Obara murdered Australian/English women several years ago and the court sentenced him a life in prison a few days ago. He received international attention. But, Japanese traditional media never ever even hinted that he was, in fact, a Korean descent. Most Japanese don’t even know what his previous nationality was. And they don’t need to Know since he is Japanese after all.
The important thing is that Japan as a whole don’t fuel nationalism or hatred toward any group of people. Of cours, this kind of things can’t be hidden in this information age. Yes, there are some blogs or forums attract those who like to talk about this kind of things, but they are minority.
There are 3 things that anger some nationalistic Japanese.
1. Most Japanese media deliberately hides some “sensitive information”. A self-censorship of the media.
Obvious example of this is this. If you compare an article of Asahi newspaper with one from another newspaper, you’ll notice Asahi’s article and the other report the same crime, but the name of the suspect differs. What does this mean? That’s something to do with his/her nationality or ethnicity.
3. Koreans steal Japanese intellectual/copyrighted/cultural property and claim that everything originate from Korea.
It’s called Uriginal and Pakuri.
3. Korean and Chinese attitudes towards Japan. Or their anti-Japan education, aka brainwashing.
Some Japanese already know that many Koreans have been taught the “Dokdo is our land” song in their kindergartens for example. Japanese wouldn’t do that to kids. So, how one could rationally talk about political/academical matters with someone who’s been brain-washed in her/his entire life? Besides, much of Krean’s claim are baseless and it seems they just love to attack Japan just to bring Japan down.
Once South Korean president said that “Japan is a potential enemy and we have to beat Japan sometime.” Many Japanese just laughed ass off. But most Japanese didn’t even notice; “Noh? who?”
China is a different thing. Although China has great history and culture, Japanese never ever get along with communists anymore. Never. Japanese, in fact, like Taiwanese very much.
Over all, you may be surprised to hear the bust majority of Japanese feel positive toward Korea(n) even though as some argue that most of Japanese don’t have much interests in Korea in general. No flag burning, no beating, no killing, no raping, no nothing, nada. I saw a few incidents in TV such as Korean lady’s kimchi got stolen & eaten in a packed train. She was crying. But her kimch got eaten by somebody in a packed train? Oh well, wtf.
Oh, don’t forget, whole lot of Japanese ladies in their 40s and 50s love Korean dramas.
Trivia: Speaking of dramas, this Japanese movie is the most easiest example of what’s going on in Japan today. The movie is based on “true” story which a Korean student lost his life trying to save a Japanese life. The story is about this Korean hero and his Japanese girl friend. And he tries to save an ill-minded Japanese bustard who fell in front of a train in Tokyo. Fine. But the reality was that the Korean student AND a Japanese guy tried to save someone’s life. Besides, the Korean students girl friend wasn’t Japanese. Japanese are evil and Korean are hero. That’s kind of a brain-washing huh? Many surprised to find out that The Agency for Cultural Affairs payed the money for the movie. And Japanese Emperor had to watch this movie.
