Designed by Tezuka Architects, the Hakone Pavilion is an astounding architectural masterpiece created by piling up more than 500 timber logs. The construction is part of the Hakone Open-Air Museum, opened in 1969 as the first open-air art museum in Japan. Using 320 cubic meters of timber, without the help of any metallic parts except for the concrete base fixtures, the architects constructed the Hakone Pavilion in a sheltered space of the Museum’s grounds. It was built for the enjoyment of kids and features a climbing net for children created by artist Toshiko Horiuchi Macadam. Built as a protective space from rain and harsh sunlight, the Hakone pavilion conveys a feeling of playing outside, surrounded by nature. “Cutting-edge structural analysis has been employed to overcome the variability that characterizes timber. While employing traditional wood joints we have searched for a futuristic form, which should result in a completely new type of architecture.” When in Japan, take your kids to enjoy the astounding architecture and works of art at the Hakone Open-Air Museum.
