The Hakone Open Air Museum is a must see on any visit to Hakone.
Stretched out over a grassy hillside, the park features sculptures by leading international artists, some indoor exhibitions of sculpture, and a pavillion with works by Picasso.

Artists with works of art on display include Henry Moore, Constantin Brâncuși, Barbara Hepworth, Rokuzan Ogiwara, Taro Okamoto, and Kōtarō Takamura.
Suggested Activity
Become a Samurai in Tokyo
Who doesn't want to swing a sword and emulate the warriors of feudal Japan? Experience being a samurai for yourself in one of the coolest activities in Tokyo. During your intimate lesson, you’ll get to dress up in a samurai outfit and train with a traditional katana (single-edged samurai sword)!

The Picasso Pavillion contains 300 pieces by the very prolific Pablo Picasso.
