After performing this cartoon's title song before a packed audience, popular singer Betty Boop climbs into her private airplane and embarks upon a journey to Japan (getting directions from the Statue of Liberty along the way). Upon her arrival, Betty is greeted by cheering throngs of Japanese citizens who have festooned the city with posters bearing her name. During her subsequent stage performance, Betty emerges from a paper lantern and, backed by a chorus of doll-like geishas, offers a reprise of "A Language of All My Own" in Japanese. (One cannot imagine this delightful cartoon being made a few years later, at the height of WW2).
