I'm not sure, but I think they're not ALWAYS the same. My chinese friend who is taking Japanese said that some kanji had different meanings from what she learned in Chinese. But I think many are still the same. My mom recognized all the characters I showed her because she had studied them in Korean school a loooong time ago. But they are the more basic characters. So, maybe the basic characters are preserved, but as they get more complicated, the meanings change? O_o;;
