Highly developed attention to detail. Character writing, called kanji 漢字, is mentioned as the main reason why the Japanese generally have a highly developed eye for detail. By comparison, the compulsory 2,136 characters are taught by 9th grade. Only after mastering them can one read newspapers and literature. Anyone who is at least a little familiar with Japanese characters knows that even the slightest differences play a big role in the meaning of seemingly similar characters. So even for the complexity of the script, precision and accuracy in everything to do with Japanese people is important.
