Japanese people like harmony. Japanese society looks harmonious and homogenous. But how comes that in a country that values harmony and uniformity there are 4 different PC encoding types for Japanese characters, used only in Japan ? There is EUC, SHIFT-JIS, ISO-2022-JP and Unicode. In Europe, the Americas, Africa and Oceania, there are a few systems, but it is possible to use only one encoding type because people of all these countries agreed on one common system. One country in Europe only has one encoding system. Why can't the Japanese agree on only one for Japanese language ?

Then, all Europeans use 50hz TV's and all North Americans 60hz TV's. But the Japanese use 60hz in the West of Japan and 50hz in the East. That looks very unharmonious. How do the Japanese deal with that ?
