Spotted this through the window of a game center in Shibuya last night and had to go inside to take a closer look. When I first arrived in Japan back in 1999, Dance Dance Revolution was the hot arcade game. It was basically the old Simon electronic game combined with music and using feet instead of your hands. Well, meet Mai Mai. My friend described it best: "Simon meets Astroids meet Tempest meets Space Invaders on acid. Or some form of Japanese martial arts training. Possibly an epilepsy test."
