Meguro Parasitological Museum is the only establishment in the world entirely devoted to parasites. You read correctly, this quirky little museum has become a popular offbeat attraction – and even date spot – in the relatively quiet Meguro neighbourhood.

The museum is home to a collection of parasitic creatures from all facets of life. Typically there are a few hundred jars of parasites on display on any given day. As you wander through the exhibit, keep an eye out for the star of the show, an 8.8-meter tapeworm that lived in the body of a patient who ate a fish containing a young parasite.

Admission is free, but the museum always accepts donations to assist in its maintenance and operation.
