The second phase of renovation work at Lake Biwa Museum, Shiga Prefecture, included the establishment of a new "Adult Discovery" and the renovation of the "Discovery Room," restaurant, museum shop, atrium, and special displays room. "Adult Discovery" is a learning and exchange space that aims to respond to the inquisitiveness of adults and be used repeatedly, conveying the fun of museums, raising interest in Lake Biwa, and fostering a desire to participate in activities in the community and the museum. There are more than 1,000 specimens of animals, plants, minerals, etc., and the functions and space have been created to encourage activities such as being surrounded by the specimens, looking at them, selecting and picking them up, observing them under a microscope, researching them in an illustrated book, and asking questions to the curators. There is a corner where you can carefully observe the specimens and experience how to sketch them, and an open lab where you can experience museum research and data organization right in front of you. The Discovery Room is an experiential space that serves as the "entrance to the museum," where you can learn and discover through stuffed animals and the five senses. [Customer's Issues/Requests] Shiga Prefectural Lake Biwa Museum opened in 1996 (Heisei 8) with the theme of "Lakes and Humans," and 20 years have passed since then. During this time, investigations, research, and the collection of valuable materials have been carried out through exchanges and collaborations between museum staff and various people outside the museum. The museum was required to communicate these results to more visitors in the form of displays, and to create a system that would lead visitors' interests and curiosity to new developments through exchange activities that utilize the museum. [Solution] We have created an exchange hub that encourages participation, discovery, dialogue, and exchange and nurtures people who will lead the next generation, by establishing the first real intellectual space in Japan that adults can enjoy, "Adult Discovery," a discovery room where you can learn and discover with your five senses, and other facilities. [Customer's Comments] The second phase of renovation has reconstructed the exchange space, enhanced exchange functions, and increased the number of visitors. <Our project members> [Sales and project management] Haruya Miwa [Planning] Taihei Samejima [concept design and planning] Tadashi Yuasa, Kaoru Sone, Rie Morita, Mina Miyagi, Masaaki Mitsunaga, Reiko Kagawa [Sign and graphic concept design] Rie Morita, Mina Miyagi, Yuki Higashihara [Production and construction] Hironari Ota, Yuki Higashihara, Yuka Tabata, Takahiro Nakayama [public relations] Hiroko Yamase, Nobuaki Yabe
