Teriyaki-chan is the Japanese DJ of Funami FM in the Downtown District of Anywhere City in Grand Theft Auto 2. She plays acid-type drum and bass electronic music. She is likely a member of the Yakuza, and comes across as a frantically screaming Japanese woman (in a varied high-pitch voice) whose speech is unintelligible apart from a few random phrases of English. She is accompanied by the pre-recorded voice of a male announcer.
Her name comes from the food item teriyaki, a Japanese meat dish, and "-chan", a diminutive.
