Hakone Open-Air Museum

The Hakone Open-Air Museum is a sculpture park and museum in Hakone, Kanagawa Prefecture, Japan, combining outdoor sculpture displays with indoor galleries. It opened in the late 1960s and is known for integrating modern and contemporary sculpture with the natural landscape.

The grounds host hundreds to over a thousand works across landscaped lawns, wooded slopes and terraces, with large-scale outdoor pieces by international artists. A dedicated indoor space, the Picasso Pavilion, exhibits works and ceramics by Pablo Picasso alongside rotating exhibitions.

The museum’s layout encourages walking between dispersed sculptures with views of surrounding hills; facilities include sheltered galleries, a café and rest areas. The collection emphasizes large-scale, durable works suited to outdoor display and offers year-round access with seasonal planting changes.

Hakone Open-Air Museum is located in the Hakone area of Kanagawa Prefecture, within the volcanic Hakone region southwest of Tokyo and accessible by regional rail and road links from Odawara and Tokyo.
