It seems that arcade games with unconventional interfaces are the latest cultural phenomenon in Japan.  The most popular of these games is Dance Dance Revolution, in which players "dance" to the music by hitting four large buttons with their feet in order to match arrows displayed on the screen.  Another such game is Samba De Amigo, in which players shake a pair of maracas in time to Latin-flavored music.  I admire these games because they bridge the interactivity gap between the player and the game screen, breaking down the traditionally static nature of video games by introducing a performance element.  They also appeal to a broader spectrum of people, making a visit to the arcade a more social activity.
While video games that reach the American market are traditionally targeted at adolescent males, Japanese video games have long offered a diversity of experiences suitable for both sexes and a variety of interests.  There are games that simulate dating, cooking and the operation of a train; there is even an upcoming PlayStation title that lets players simulate being on a diet.  But a game that was recently presented at the Tokyo Gaming Convention simulated an activity I thought I'd never see in a video game: ass spanking.
That's right: Boong-Ga Boong-Ga ("Boong-Ga" is Japanese for "Spank 'Em") is a game that features a woman's shapely rear as an input device.  A video screen displays the face of the woman to whom the exposed cheeks presumably belong.  She reacts when players pick up the pointing finger controller and jab her in the posterior as hard as possible.  It's unclear to me how exactly one would excel at Boong-Ga Boong-Ga, but apparently those who figure it out are rewarded with a novelty keychain shaped like a pile of feces.  The game also dispenses a card at the conclusion of gameplay; according to the company literature, this card "explains your sexual behavior."

The Engrish phrases on the side of the arcade machine make the game even funnier:

What
the heck.!!
it's just waiting
for the stress of
city life Give a shot
HAVE A FUN!!

The official brochure explains how "the face expression of the character will change as they scream and twitch in pain.  The funny face expressions will make people laugh and relieve the stress."  The brochure also lists the many characters that players can choose to spank, including the gangster, the mother-in-law, the prostitute, and the child molester.  Oh, those child molesters... they're always adding to the stress of city life.
