The issue is that its not theirs and that is exactly the problem. You can't just use China's writing system and try to make it fit to your language. Japan might have a high literacy rate but that is despite their horrible system and not because of it. Plus you can argue that they're not really literate, they just limit themselves to using a small portion of their 'kanji' and write little hiragana hints that tell you how to pronounce the written symbols for all the rest.
