We renewed the language exhibition at the National Museum of Ethnology (Minpaku). We built a new database to reform the system to make it possible to manage all the contents of the different exhibitions in one place. The results of researches are now easier to update. In addition, we took extra caution in designing operation flows and visualized data to make sure that visitors of all ages can learn how to enjoy and study languages. The language exhibition has become more user-friendly for visitors, researchers, and administrators alike by reconstructing the system and UI.
