In our first campaign for Duolingo, the world's #1 language app, we decided to give language-learning mistakes a reputation makeover. Instead of feeling self-conscious about Japan's unorthodox usage of English in public signs, menus, and advertising, we saw beyond the obvious and found profound, poetic beauty. Thus the Museum of Wonky English was born: the first institution in the country to shed light on the art of mistranslation. What started as a local brand activation made worldwide headlines and gave people another reason to visit Tokyo. How did we do it? With precision and elegance.
