Nagoya City Science Museum, beloved by local citizens since its opening in 1962, reopened on March 19, 2011. Starting with the commissioning of the master displays plans for four large-scale displays, we were involved in a variety of work, including displays working drawings, displays production and construction, and the master plan and interior administration of the world's largest planetarium. In addition to space creation, after the museum opened, we also operated the museum shop and museum cafe & restaurant, and were in charge of maintenance work for the large-scale displays equipment. In order to contribute to attracting visitors to the Nagoya City Science Museum, we have undertaken a wide range of activities, from space creation before the museum opened to space revitalization after it opened.
