The Parasite Museum, is probably the only museum in the world dedicated entirely to parasites. You can learn about the parasites, who live, as terrible as it sounds, even in our bodies right now. You don't have to fear them or feel disgusted, but to only be aware of them and see them, if you wish, up close.
By the way, in the museum you can see the longest parasitic worm in the world, 8.8 meters long!
The explanations beside the exhibits are in Japanese. Visitors are offered a voice translation tool for English.
