Japan's first open-air art museum, established in 1969, displaying around 120 sculptures in seven hectares of landscaped grounds in the mountains above Hakone-Yumoto. The collection spans major 20th-century Western and Japanese sculptors: Rodin, Bourdelle, Moore, Picasso, and Taro Okamoto are all represented. The indoor Picasso Pavilion holds over 300 works.
The outdoor foot baths scattered through the grounds add an appealingly Hakone-appropriate element to the visit — soaking tired feet while looking at modern sculpture in the mountains is a combination that somehow works. Admission around 1,600 yen; a short walk from Chokoku-no-Mori Station on the Hakone Tozan Line.
