The Meguro Parasitological Museum is the world's only museum devoted to parasites — small, free and oddly compelling, with some 300 specimens including a preserved 8.8-metre tapeworm. It's a genuinely offbeat 30-minute stop, and a quirky gift shop sells parasite keychains. Closed Mondays and Tuesdays.
