Kogane-Zutsumi
This 180m-long, 4m-high embankment was built in a single night by Kira Kozuke no Suke and his fiefdom to prevent his lands from water damage.
Since then, the land in this area remained well without damage, earning the nicknamed Kogane-Zutsumi in his honor.
It's now known as a popular cherryblossom spot, decorated with illumination events from late March to early April.
