Due in part to the western influence, Japan has received many effects, both good and bad. In the same way that various cultural influence has helped countries such as the United States to gain perspective and broader its horizons, so has western influence helped to expand the cultural viewpoints of Japan. Also, western influence has opened the minds of the Japanese people, allowing them to accept new ideas and concepts. Some of these ideas include music, movies and even fashion. Perhaps it is due to western influence that the country of Japan possesses the technological importance that it holds today.
However, despite the many positive effects of western influence on Japan, negative effects have also surfaced. Although western influence did broaden Japanese horizons, it destroyed a good portion of the countries individuality. Keep in mind that the Japanese possessed a fairly unique culture, and the loss of that culture is a great blow to the individuality of the world. Also, with the following of the new ways, the Japanese people may easily have forgotten their traditional ways.
This is what the Samurai tried to prevent. They did not want Japan to lose the focus of the past, and all of the things that had allowed the country to come so far and stay in power for so long. The Samurai were deeply rooted in tradition, and perhaps this dedication to tradition is shown more than anything else throughout the film. However, at the same time, we must be careful that we do not come to rely too heavily on tradition, this will lead to failure in the same manner that forgetting the lessons of the past eventually will.
