Japan is one of the developed countries in the world, basically Japanese are always looking for perfection. They love doing work after work that's why they have little bit opportunities to entertain themselves. Without refreshing no one can gain the hope of life. Besides work everybody should enjoy his or her life. Except this you will become a robot, then you only find yourself in working, after that you feel extremely frustrations and it will lead you to dangerous way of Life.
This is the difference between the working conditions in Japan and Germany. In Japan, there is no divide between work and life. People work for 12-13 hours a day, and even after that time they think about work. They hardly ever take holidays or vacations. The situation is different in Germany. They work for 7-8 hours a day, and after that they don't bother about work. They take regular vacations with their family, unlike the Japanese.
I think it is very foolish to dedicate his entire life to the work. The Japanese are very strange people. I don't understand their culture. They have a very strange TV show of a sexual nature. I watched them and I do not understand how can you. Although to be honest it look very funny.
