Wasei-kango (Japanese: 和製漢語, "Japanese-made Chinese words") are those words in the Japanese language composed of Chinese morphemes but invented in Japan rather than borrowed from China. Such terms are generally written using kanji and read according to the on'yomi pronunciations of the characters. While many words belong to the shared Sino-Japanese vocabulary, some kango do not exist in Chinese while others have a substantially different meaning from Chinese; however some words have been borrowed back to Chinese.
