Sekiyado Castle

Sekiyado Castle is a fortress in Noda, Japan, rising at the confluence of the Tone and Edogawa rivers, comprising four levels with turrets and stone walls. The structure combines gates in traditional style with a central tower that rises above the flat landscape.

Tokugawa Ieyasu ordered the fortress rebuilt in 1590 after the original structure was destroyed during battles against the Hojo clan. Matsudaira Yasumoto led the work, constructing the castle at this strategic point to control the waterways.

The museum inside displays tools and models explaining how people once controlled flooding and lived with the two large rivers. The exhibition helps visitors understand why this fortress was built at exactly this point where waters converge.

Buses from Tobu Dobutsukoen or Kawama stations bring visitors near the site, where information is available in Japanese and English. The location between the two rivers makes the site especially rewarding in clear weather when views extend far.

The observation room at the top features windows with drawn markings showing which geographical points in the Kanto plain are visible. These illustrations help visitors identify distant mountains and urban areas in the panorama.
