Flush any misconceptions about human waste out of your system at this new show at the futuristic, bayside Miraikan science museum. The curators take a humorous yet educational look at different toilets around the world and even a possible space toilet that could be used to grow plants. An unchi (poop) yurukyara (mascot) ambassador is your guide to an exhibition whose centerpiece is a giant 5-meter toilet that allows visitors to slide into it after donning feces-shaped hats to simulate a trip into the sewer.

¥1,200. Miraikan, until Oct 5. 2-3-6, Aomi, Koto-ku. Telecom Center. Tel: 03-3570-9151. www.miraikan.jst.go.jp/en
