How's an air-shower grab ya? Well, that's exactly the sort of fun you can choose to subject yourself to if you happen to live in the Riche Tamagawa Riverside complex located in Tokyo's Ota-ku. Located near the entrance, this “air-shower” system is meant to remove pollen, dust and other allergens from your person before you enter your immaculate sanctuary. It's 2 meters tall and 90 centimeters wide, and contains 12 nozzles that pump air all over you for 20 seconds, presumably enough time to fluff you up real good.
