This unique museum celebrates Hakone's centuries-old tradition of himitsu-bako (secret trick boxes) and wooden marquetry. Visitors can marvel at intricately crafted puzzle boxes that require dozens of precise steps to open, and even try their hand at solving them. It's a delightful, interactive stop where you can appreciate local craftsmanship and purchase authentic, mind-bending souvenirs.
Pay the small extra fee to join the DIY workshop where you can assemble and take home your very own working secret puzzle box.
