Finally there are the castle sites that have not been maintained or developed to any degree, and may have few markings or signs. Historical significance and local interest are too low to warrant additional costs. This includes Nagasawa Castle (Toyokawa, Aichi), Sakyoden Castle (Toyohashi, Aichi), Taka Castle (Matsuzaka, Mie), and Kuniyoshi Castle (Mihama, Fukui Prefecture). Castle sites of this type also include nearly every area marked Castle Mountain ( Shiroyama) on the maps of towns and cities across Japan. Because the castle was small or may have been used for a short time in centuries past, the name of the castle is often lost to history, such as the Shiroyama at Sekigahara, Gifu Prefecture, or the Shiroyama between Lake Shōji and Lake Motosu near Mount Fuji, Yamanashi Prefecture. In such cases, locals might not be aware there ever was a castle, believing that the name of the mountain is just a name. Detailed city maps will often have such sites marked. At the site, castle-related landscaping, such as ramparts, partly filled wells, and a leveled hilltop or a series of terraces, will provide evidence of the original layout of the castle.
