Who needs to speak Japanese? There’s a lot you can say with traditional hand gestures and body motions that are universal as well as uniquely Japanese. This whimsical look at “the language of no language” will teach you to hurl insults, flirt, agree, excuse yourself, cross the street, and even make promises—wordlessly! (And who is that stoic guy wearing a suit in all the photos?) Finally, a way to tell someone at a loud party, “Your underwear is showing,” in four easy hand motions. This is a book for the serious student, the class clown, and the crazy guy at Akihabara Station hoping to communicate with Godzilla.
