Chiryu city in Aichi Prefecture was the 39th of the Fifty-three post-towns of Tokaido. The site is along the old Tokaido Street where Honjin (officially appointed inn) was once positioned. It is fair to say that it is the center of the town in terms of local history. Based on such historical importance, a Chiryu-based global robot manufacturing company decided to purchase this ownerless land and make a facility for regional contribution. The program is a complex of an afterschool(=Terakoya) that teaches natural science through scientific experiments in English, as well as a cafe with kitchen studio in which local people, especially mothers, are able to gather and relax. The client had an intention of displaying the way to internationally succeed through the skills of natural science to the local children, as their company has been achieving. To match the ambition, we built two pillars: one was to inherit historic context respecting the history of the site, while the other was to conform to the natural science on the ground of science experiment and robot technology background of the client.
