Kyowa-go (協和語 Kyōwa-go, "Commonwealth language" or "Concordia language") or Xieheyu (Chinese: 協和語/协和语; literally: "Harmony language") is either of two pidginized languages, one Japanese-based and one Chinese-based, that were spoken in Manchukuo in the 1930s and 1940s. They are also known as Kōa-go (興亜語, "Asia development language"), Nichiman-go (日満語, "Japanese-Manchurian language"), and Daitōa-go (大東亜語, "Greater East Asia language").
The term Kyowa-go/Xieheyu is derived from the Manchukuo state motto "Concord of Nationalities" (民族協和 mínzú xiéhe) promoted by the Pan-Asian Movement. The pidgin language resulted from the need of Japanese officials and soldiers and the Han and Manchu population that spoke mainly Chinese to communicate with each other. Manchukuo officials later dubbed the pidgin language "Kyowa-go" or "Xieheyu", meaning "Concord language". However, the Japanese also wanted to implement their own language in Manchukuo, saying that Japanese is a language which has a soul, so the language must be spoken correctly.
It was also believed that many of the expressions of Chinese characters in manga (e.g. aru) are derived from Japanese-based Kyowa-go. Hence, it is typical of Chinese characters in anime shows to speak in that manner.
It was also believed that many of the expressions of Japanese characters in movies set in the Second Sino-Japanese War (e.g. 悄悄地进村，打枪的不要) are derived from Chinese-based Xieheyu. Hence, it is typical of Japanese characters in movies shows to speak in that manner.
The Japanese were also known to use pidgin languages in Japan itself during the 19th and 20th centuries like Yokohama Pidgin Japanese.
