Japan's Agency for Cultural Affairs has decided to designate a French-styled residence in Ehime Prefecture as an Important Cultural Property. Located on the perimeter of the Matsuyama Castle grounds, "Bansuisou" was built in 1922 as the residence for Count Sadakoto Hisamatsu, a descendant of the Matsuyama Daimyo. Count Hisamatsu had a long history with France, having first gone there to study when he was 16 years old. He then graduated from French military academy, École Spéciale Militaire de Saint-Cyr. He was later appointed as the military attache to the French Embassy before returning to Japan in 1906.
