The Nagoya City Science Museum, a beloved institution for citizens since its opening in 1962, reopened on March 19, 2011, after renovations. Starting with the commissioning of the basic displays plan for four major displays, we were involved in various tasks, including displays displays working drawings and construction, as well as the basic planning and interior administration of the world's largest planetarium. Furthermore, beyond just space creation, after the reopening, we also handled the operation of the museum shop and museum cafe & restaurant, and the maintenance of the large displays equipment. Our efforts extended from space creation before the opening to revitalizing it afterward, all in an effort to contribute to attracting visitors to the Nagoya City Science Museum.
