Lake Biwa Museum opened in 1996 with the mission of building a better coexistence between the lake and humans together with the local people, and underwent renovation work over three phases over a period of six years from 2015. This third phase involves the renovation of displays rooms A and B. displays displays A is entitled "4 million years of the lake and us - the ever-changing Lake Biwa" and introduces the changes in Lake Biwa, nature, and creatures 4 million years ago, along with their relationship with the current environment. Each corner conveys the story of Lake Biwa and its creatures, which have continued to change dramatically, and the charm of the Lake Biwa field, through the numerous fossils and geological specimens that have been collected since the museum opened, and reconstructed dioramas that allow visitors to experience the environment of the past. The B displays room is titled "20,000 Years of the Lake and Us - A History of Nature and Life," and introduces how humans have dealt with nature in the forest, waterside, lake, and village. Using the dragon, a symbol of nature from the human perspective, as a navigator, the exhibition follows the environmental history of Lake Biwa and explains how it is connected to our current lives (displays Room C). [Social Issues/Customer Issues/Requests] The renewal challenge was to incorporate the latest technology into the old displays to evolve them into more advanced displays, and to develop the museum with universal concept design in mind to make it easy for everyone to use and enjoy. [Solution] By using new technology to upgrade the existing exhibits, such as a skeletal fossil of the Zdanski elephant and a "half-body, half-bone" specimen that was restored using a 3D scanner, and a Maruko boat with sails reconstructed using an AR app, we were able to make the latest displays results easier to understand and experience. Furthermore, from the design stage onwards, citizens and experts were invited to evaluate displays, and the displays was designed with universal concept design in mind, with ramps installed, exhibits that can be touched, mirrors installed so that people using stretchers can easily see displays, and explanations written in mirror writing. [Customer feedback] displays concept design was unified from the first to third periods, and displays incorporated the latest technology. displays introduction of experiential displays such as tactile and olfactory displays made displays enjoyable for everyone. Furthermore, the design that took universal concept design into consideration has made the museum easy for everyone to use and enjoy. <Our project members> [Sales and project management] Hiroko Yamase, Haruya Miwa [Direction] Tadashi Yuasa, Koki Mizuno [design, layout] Tadashi Yuasa, Koki Mizuno, Reiko Kagawa [Sign and graphic concept design] Tadashi Yuasa, Koki Mizuno, Yuki Higashihara [Production and construction] Hayato Ichimanda, Yoshito Inoue, Yuki Higashihara / Nomura Techno Co., Ltd.: Masaru Oishi
