Kyowa-go (協和語,Kyōwa-go; "Commonwealth language" or "Concordia language") orXieheyu (Chinese:協和語/协和语;lit. 'Harmony language') is either of two pidginized languages, oneJapanese-based and oneMandarin-based, that were spoken inManchukuo in the 1930s and 1940s. They are also known asKōa-go (興亞語; "Asia development language"),Nichiman-go (日滿語; "Japanese-Manchu language"), andDaitōa-go (大東亞語; "Greater East Asia language").

The term Kyowa-go/Xieheyu is derived from theManchukuo 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 thatJapanese is a language which has a soul, so the language must be spoken correctly.

Kyowa-go/Xieheyu died out whenManchukuo fell to the SovietRed Army in the last days ofWorld War II. Documentation of the pidgin language is rare today.

It was also believed that many of the expressions ofChinese characters inmanga (e.g. aru) are derived from Japanese-based Kyowa-go. Hence, it is typical of Chinese characters inanime shows to speak in that manner.

It was also believed that many of the expressions ofJapanese characters inmovies set in theSecond Sino-Japanese War (e.g.悄悄地進村，打槍的不要) are derived from Mandarin-based Xieheyu. Hence, it is typical of Japanese characters inmovies shows to speak in that manner.

The Japanese were also known to use pidgin languages in Japan itself during the 19th and 20th centuries likeYokohama Pidgin Japanese.

Kyowa-go is characterized by a particlearu, omission of someparticles, and many loan-words fromMandarin.

Original Japanese:私は日本人ですWatashi wa nipponjin desu meaning "I am Japanese".

Original Japanese:お孃さんは綺麗ですねOjōsan wa kirei desu ne meaning "Isn't your daughter beautiful?"

Original Japanese:貴方が座る椅子はありませんAnata ga suwaru isu wa arimasen meaning "There is no chair for you"

Exclamation of surprise from Chinese.

Xieheyu sometimes usessubject–object–verb, the normal Japanese word order, which is different from Mandarin.
