Ever since the first announcement by former President Kim Dae-jung that doors will be open for Japanese culture, Japanese cultural products have been coming in steadily and slowly. Now after the last three stages to come into the country, the government announced that the doors will be thrown wide open to the culture. The government said that adult only movies, pop music, and games are the fields that are to come in for the fourth opening. By the end of the year, television show programs and theater animations will also be able to come in. So now practically, the doors are completely open to the Japanese. For over half a century Japanese public culture have been banned because of worries of what effect it would have on the citizen emotions and to related industries. However avoiding Japan's culture because of the country's historical relations that made us uncomfortable is no more unacceptable in the world today. As our singers and actors have been largely going into the East Asian markets, including within Japan, and are even making a syndrome called hanryu, there is no reason not to accept Japanese culture. Our cultural confidence has gone up. Also our cultural potential is endless. Japanese is just one part of the world culture we experience everyday. But some parts like the adult films that have grotesque details which are not familiar to Koreans needs filtering due to concerns about giving negative sexual influence. Most people were aware of the fact that Japanese culture will threaten our culture which was thought to be as a little bit backward compared to the technically modernized fancy culture of Japan. But these worries were soon gone, Japan's movies, videos, and music did not do much well in our market. On the other hand our movies, on-line games, dramas, and musicians have made progress entering Japan. Japanese culture coming in is now a trend in our era that we cannot set back. The influence of the unique culture of the Japanese have been rapidly growing through mania groups although there have been regulations on importing the culture. It is because the culture itself is now coexisting with our own culture. Until now internet file downloading and illegal copying of files have been the gateways to Japanese culture. These irregular methods were the routes in which the negative aspects of the culture of Japan came into Korea. But if the government shows official action in sorting what to import among the Japanese cultural products, there will be a chance for the people to meet good quality culture contents. As along with picking out good contents the cultural identity of our youth should be thoroughly prepared. If one is exposed to the culture from early age, there is a chance that they will not be sure of there cultural identity as a Korean. So following the opening, the education on strengthening our identity is very much in need. Preparations as to this aspect should be perfect. Now the focus is not only on preparing not to be absorbed, but on the competitiveness of our culture goods is in need as well. We should remember that even in the situation when imports were banned Japanese animation and games were an ultimate popular product among the young people in our country. We need deep research in the products that will be shown to us not in the distant future, but right now. As popular culture is also a product, making competitive goods are also important. The government should be investing more in the cultural department to protect our own culture from getting harmed by others. Although confidence in our own culture has risen and most people do not worry about the opening, it is never harmful to be prepared.
