Simplified/Traditional Chinese characters commonalities with Japanese Kanji
It's true to state that "traditional chinese characters are more similar to Japanese Kanji than simplified chinese." 

In more example, you are going to find Japanese Kanji and traditional chinese characters are identical due to the fact that Japanese adopted Chinese Characters much earlier. 
Chinese character simplification only started in 1956 (quite recent in comparison).

Japanese has also gone through a simplification process called "Shinjitai." And during the Japanese simplification, some characters went from identical to Traditional Chinese to identical to simplified Chinese. For example, 體   →体(tai). Please refer to this page for more example, http://en.wikipedia.org/wiki/Shinjitai. So only after this, some Kanji resemble the simplified Chinese characters.
