Central Masugata
The townscape of Kōjirokūji was built around the deposits of the Minotsuru River, which runs north to south, and was formed as a planned samurai town.
Bridges were built at the entrances and exits of the Kōjirokūji, which was surrounded by a river. There were also ‘masugata’ or walls built at right-angled turns at the entrances and exits to make it difficult for enemies to enter in a straight direction.
The centrally located masugata is no longer visible today due to the modern straightening of the roads. The site that remains today is a reproduction of the central masugata.
