About Sumi-mata Ichiyacho Castle and Sai River Embankment
A Historic Spot Associated with Toyotomi Hideyoshi
Sumi-mata Ichiyacho Castle is a legendary castle said to have been built in a single night by Kinoshita Toyojiro (later Toyotomi Hideyoshi) in the 9th year of Eiroku (1566). Although it is believed that construction actually took several days, this swift construction became an important strategic base that served as a stepping stone to Hideyoshi’s rise to power.
The current Sumi-mata Ichiyacho Castle (Ogaki City Sumi-mata Historical Materials Museum) is a replica castle built in 1991 (Showa 66). Inside, exhibits showcase the history of Sumi-mata and materials related to Hideyoshi. From the top floor, you can overlook the entire cherry tree-lined avenue of the Sai River Embankment, making it a popular scenic spot during the cherry blossom season.
Characteristics of the Sai River Embankment Cherry Tree-Lined Avenue
Along the embankment of the Sai River flowing at the northern and eastern edges of Sumi-mata town, approximately 800 cherry trees, primarily Somei Yoshino over 50 years old, have been planted. This cherry tree-lined avenue stretches approximately 3.7 km and is also called the “Cherry Embankment.”
The tree-lined path that forms a cherry blossom tunnel is maintained as a walking route, and in spring it becomes crowded with locals and tourists. The path leading across the Taikô Shusseki Bridge to the Ichiyacho Castle Site Park is known as a particularly impressive route.
