Tokyo has a museum for basically everything every—ranging from the free Parasite Museum to a Gas Science Museum, as well as the more traditional historical and cultural museums, you could visit a different one every day for a year. Entry isn’t always free but is reasonable, and there is always International Museum Day when many are free—although beware long crowds as this is popular. You can see the Samurai, play with some traditional toys at the Toy Museum and marvel at the fantastic costumes on display at the Bunka Gakuen Costume Museum. We even have a mega-guide to help you out.
Now, if the idea of a museum bores you stiff, wait! Tokyo has its fair share of strange ones. Why not visit the Ramen Museum in Yokohama, the Studio Ghibli Museum in Mitaka—or if you’re in the Uwajima area of Ehime prefecture, the monk-run porn-museum? If they don’t pique your interest I don’t know what will.
