The vast majority of kanji used in Japanese come from China. But a
few dozens of them have been invented by the Japanese. These kanji are
called "Kokuji (国字, "national characters").
Kokuji are used for purely Japanese words as well as for Western words
once they are well integrated into the language. While Chinese characters
usually have one or more Chinese reading (on-yomi) and one or more
Japanese readings (kun-yomi), most kokuji only have a Japanese
reading. However, a few kokuji have been borrowed by the Chinese
themselves, and these ones received a Chinese reading.
The following table lists 85 kokuji taken from Jim Breen's
kanjidic. Shro0m told me to use Unicode character entities instead of EUC and he was right.
