I would like to view the boundary survey map of roads and waterways. Also, can I see the boundary survey map on the Internet?

We can read boundary investigation figure in road ledger reading system of city hall the second floor [Yokohama Building Information Center] and city hall the second floor [road investigation section] (10-50 Honmachi, Naka-ku) . However, in the city hall, you can view the boundary survey map of the entire Yokohama city, and in each ward Public Works Office, you can view only the boundary survey map of the relevant ward. Please note that it is not available on the Internet.
※The boundary survey map for roads and waterways that can be viewed is as of the date of approval.
※The original boundary survey map is the Public Works Office of the ward, and the original boundary survey map of the city boundary can be viewed on the 22nd floor of the city hall [Road Survey Division].
