Outline of this museum

Bound by the Tone and Edo rivers, the Sekiyado-jo Museum was built atop a super levee in Sekiyado-Sangenya, Noda City. With a mission to explore a history and culture shaped by rivers, this museum opened its doors to the public in 1995. 
In accordance with an exhibition theme defined by rivers and associated industries, the history of the lives of the people living in the Tone River Basin is hereby introduced in a manner that is easy to grasp and comprehend. 
Exhibits consist of permanent exhibits that showcase–in terms of a focus on the rivers of the Boso Peninsula, transportation on waterways, and traditional industries–­the history of floods and flood control in the Tone River Basin and the culture of industries that were nurtured by rivers and of a presentation entitled The Sekiyado Clan and Sekiyado, which sheds light on the Sekiyado clan as it thrived during the Edo era. 
In addition, we conduct investigative research and collect archive materials concerning history, folklore, and civil engineering as they relate to the rivers of the Boso Peninsula and materials concerning the Sekiyado clan during the Edo era and also we seek to introduce the results of such efforts to the general public through exhibitions (special and otherwise), lectures, courses, and other activities designed to spread awareness. 
A replica of the main tower of the former Sekiyado-jo (Sekiyado Castle) was built to form a portion of the museum structure. The observation room on the fourth floor commands an expansive view of the Tone River and the mountain ranges spanning the entire Kanto region.
