The Hakone Open-Air Museum is a premier open-air sculpture museum located in Hakone, Ashigarashika District, Kanagawa Prefecture. Spanning approximately 70,000 square meters, the museum follows a 'sculpture garden' format where artworks are strategically placed within lush greenery. The defining characteristic of this museum is the seamless integration of artistic works with the surrounding natural landscape, creating a holistic sensory experience.
Opened on September 6, 1969, the museum was designed by the sculptor Takeyoshi Inoue. Over the decades, the museum has continuously expanded its collection and facilities, most notably through the renovation of the Picasso Pavilion and the installation of the 'Symphony Sculpture' (the stained glass tower). The institution is managed by the Hakone Open-Air Museum Foundation, dedicated to preserving and promoting art and culture.

The facility features a diverse range of exhibition areas. The outdoor exhibition area houses approximately 120 permanent sculptures by leading modern and contemporary artists. A standout feature is the 'Symphony Sculpture,' an 18-meter-tall tower containing 480 pieces of stained glass that creates a mesmerizing visual spectacle. Additionally, the Picasso Pavilion offers a deep dive into the sculptural works of Pablo Picasso, while the 'Manzu Room' focuses on the works of Giacomo Manzù. These areas provide profound insight into the history of sculpture and specific artistic movements.
The museum is open year-round, but the scenery changes beautifully with the seasons. In spring and summer, the deep green foliage provides a vibrant backdrop for the sculptures. Due to Hakone's unique climate, the museum can often be shrouded in mist, which adds a mystical and ethereal quality to the art displays. During the bright daylight hours, visitors can best observe the interplay of light and the colorful reflections from the stained glass elements.
For a hands-on experience, visitors can explore the 'Net-no-Mori' (Forest of Nets), an interactive art area designed for children (up to elementary school age) to touch and interact with art. Another unique way to relax is the 'Mori no Ashiyu' (Forest Footbath), where you can enjoy a soothing soak using Hakone's natural hot spring water. The museum also occasionally hosts special events such as mystery-solving programs or sticker rallies, though availability depends on the season and weather.
The museum is conveniently located right next to the 'Chokoku-no-Mori Station' on the Hakone Tozan Railway. Since the Hakone area is dotted with numerous museums and sightseeing spots, the Open-Air Museum serves as an excellent base for planning a comprehensive Hakone sightseeing route. The surrounding geography is characterized by the beautiful, mountainous terrain of Hakone.
As much of the museum is outdoors, walking shoes are highly recommended. Please respect any posted signs regarding restricted areas on the lawns. Touching the sculptures is strictly prohibited to preserve the artwork. Payments can be made via cash, credit cards, or major transportation IC cards. While English signage and some staff assistance are available, please be mindful of the rules regarding photography in certain areas.
