Wow! It's amazing that all of you can talk fluent Chinese! I'm teaching myself Japanese, and the kanji is simplified of the Chinese characters, but I can't speak Chinese.
Not to be nit-picky, but Japanese Kanji are not all simplified forms, and only the katakana were really derived from kanji as I recall (radicals, to be more precise).
As for some examples of kanji in Japanese
車 is the complex form of 车
学 is the simplified form of 學
馬 is the complex form of 马
来 is the simplified form of 來
電 is the complex form of 电
国 is the simplified form of 國
I'm semi-functional grammatically speaking in Chinese, but unfortunately I am quite lacking in vocabulary. I know about 1,200 characters or so from Japanese, and a few more from studying Chinese or learning how to convert between simplified and complex, so I often rely on that to either create words when I need them, or more often just try to understand what is written.
