Yokohama Pidgin Japanese
Yokohama Pidgin Japanese, Yokohamese or Japanese Ports Lingo was a Japanese-based pre-pidgin spoken in the Yokohama region during the late 19th century for communication between Japanese and foreigners, mainly English speaking westerners and Chinese traders. Documentation of Yokohama Pidgin Japanese shows that it was not a stable pidgin, as it often varied between individual speakers, often dependent on the first language of the speaker.
