Our guide
Saga Castle, in the city of Saga, was the home of the Nabeshima clan, daimyō of the Saga Domain. It is a castle of the plains rather than of a hill or mountain, and it was also known as Shizumi-jō, the “Submerged Castle”. Our source says little more than that, so this page is short.
We have not checked opening hours or a public-transport route, so plan the journey on the map and look for local information before you go.
