[Project Summary] Linking displays with scenery, fields, life, and thoughts. 20 years have passed since the museum opened, and the relationship between the lake and humans has been deepened through displays. concept design, which links displays with scenery, fields, life, and thoughts, is based on the changes and progress of 20 years in each habitat, and the relationship with people, and through experiences, dioramas, and live-animal rearing, it truly presents the current state of Lake Biwa. In the "Creature Collection" in displays Room C, a space is created where visitors can feel the beauty and diversity of the creatures living in Lake Biwa and its catchment area at a glance. In the Aquatic displays Room, underwater creatures are visualized, which leads to an interest in living creatures. With the addition of the popular Baikal seal and the "Micro Aquarium" which handles microorganisms, the museum has attracted many visitors and researchers as a new form of museum. [Customer's Challenge] 20 years after the opening, displays have been renewed and the aging facilities have been updated. The mission of the museum was to make a new start as a comprehensive museum that would fulfill the role that the original Lake Biwa Museum aimed for, and would evolve further to be familiar and utilized by the people of the prefecture. In addition, regarding the aquatic displays, the museum was required to displays the Baikal seal, the only animal in the world that lives in fresh water, and to widely communicate its ecology to the people of the prefecture. The client's request was to create displays that would be enjoyable and understandable for a wide range of people, from children to adults, with Lake Biwa at the center. [Solution] In displays Room C, visitors of a wide age range are given an explanation of the nature, ecology, folklore, and creatures of Lake Biwa through hands-on experience. In the aquatic displays, the museum also focused on the very small plankton, and introduced the shape and ecology of plankton in a lab format, creating displays that is unique in the country. <Our project members> [Development, sales, project management] Haruya Miwa [Research and planning] Taihei Samejima [design, layout] Masaaki Mitsunaga, Kaoru Sone, Tadashi Yuasa, Rie Morita, Mina Miyagi [Sign and graphic concept design] Satoko Hasegawa, Nanae Hori [Production and construction] Yoshito Inoue, Hayato Ichimanda, Goro Yamano, Ryuichi Shimada [public relations] Hidetoshi Tsukahara
