Kumamoto Castle entry and walls
The signature curved stone walls, known as musha-gaeshi, surrounding the castle were designed to prevent attackers from penetrating the castle. "Musha-gaeshi" literally means repelling warriors. Also notice the stone steps in the foreground which lead to the castle sitting on the hilltop.
On my way up to the castle, I was drawn to the contrast between the delicate blossoms and the unyielding stone wall.
I wonder how many warriors walked up these steps in the 400 years the castle was inhabited.
