Located in Tokyo, the Museum is the only parasite museum in the world. Opened in 1953, it has more than 45,000 objects, including one 8.8-meter-long tapeworm taken from the body of a 40-year-old man. Even if the museum is not big, you need some strong encouragement to finish the tour. When you watch the jars of parasites, you can imagine some of them may have inhabited in your body; chilling indeed!
