Bamboo English

Bamboo English was a Japanese English-based pidgin jargon developed after World War II that was spoken between American military personnel and Japanese on US military bases in occupied Japan. It has been thought to be a pidgin, though analysis of the language's features indicates it to be a pre-pidgin or a jargon rather than a stable pidgin.

It was exported to Korea during the Korean War by American military personnel as a method of communicating with Koreans. Here it acquired some Korean words, but remained largely based on English and Japanese. Recently, it has been most widely used in Okinawa Prefecture, where there is a significant U.S. military presence.

The Ogasawara Islands feature a similar form of Japanese Pidgin English referred to as Bonin English. This contact language was developed due to a back-and-forth shift in dominant languages between English and Japanese spanning over one hundred years.

The name Bamboo English was coined by Arthur M. Z. Norman, in the article in which he initially described the language.
