In Japanese, the Kanji alphabet uses mostly Chinese characters that represent ideas instead of sounds. Therefore, each kanji character can be read phonetically either in Japanese or Chinese. The word 'ninja' comes from the Chinese characters 'nin' and 'sha' (which basically mean 'stealth' and 'person'). Those same characters, in Japanese kanji, are read as 'shinobi no mono'. So the Japanese word for 'ninja' is 'shinobi'.
