This is a demo kiosk for OneeChanbara Z2: Chaos at the Tokyo Game Show, and as you can see, to try the game you have to stick your head into the boobs of a huge bikini cowgirl..
Kotaku, where I found this, thinks that this display is embarrassing, but I’m into anything that has to do with sticking your head into boobs.. even if they are giant anime ones.
Also, what do you expect from a game that has this in it?
