Japanese

Japanese is a language spoken by 130 million people in Japan and Japanese emigrant communities around the world.

An advertisement for a magic translator's services that appeared in the classified section of an issue of the Quibbler listed several languages available for translation, including Chinese, "Eastern European" (presumably Russian or another language in the Slavic family), Japanese, and the Latin languages (French, Italian, Portuguese, and Spanish).
