Kokura Castle Japanes Gaeden, which has been recreated on its original site, includes a genuine samurai-style mansion called a shitayashiki, or "second house" that served as the castle annex. Other than the permanent construction display that featured the theme of Reiho(manner), I hold a plan exhibition to introduce Japanese traditional life culture to five times a year. It is hoped that this beautiful facility will inspire visitors to clearly imagine the life of nobility in the kokura area during the Edo Period.
