William Kumamoto National Hospital (https://kumamoto.hosp.go.jp/patients_attending_list.html) has history. During the Seinan War (which coincided with the American Civil War), it was carved out of the castle to “treat” those horribly wounded by muskets and shrapnel in an era before morphine (illustrated below). A good way to visit is to take the tram and walk up the hill; this gives an idea of what attackers were up against when faced by defenders. A delightful aspect about Japanese hospitals is that citizens paint absolutely wonderful works and donate them. The hospital is a museum in itself. Even if you are not in need of medical attention, it is worth a visit just for the art.
