Atayal people
Yilan Creole Japanese is a Japanese-based creole of Taiwan. It arose in the 1930s and 1940s, with contact between Japanese colonists and the native Atayal people of southern Yilan County, Taiwan. The vocabulary of a speaker born in 1974 was 70% Japanese and 30% Atayal, but the grammar of the creole does not closely resemble either of the source languages.
