Kasama Castle is classified as a mountain castle, and is located in Ibaraki Prefecture. During the pre-modern age, it found itself within the borders of Hitachi Province. It is associated with the Kasama, Makino clans. Dates in use: 1219 - 1871.

All but forgotten since the castle was decommissioned in the early Meiji period, it seems the ruins of Kasama castle will finally be getting some attention. The local government announced in March, 2011 that a large-scale survey would be undertaken of the site. A budget of ¥5,740,000 has been allocated. There are exceedingly few examples of Mountain castles with stonework remaining in the Kantō region, hence the interest.

Fortifications were established atop Mt. Sashiro during the Kamakura period and continued to be in use for over 600 years. Little remains of the castle except for some stonework, one relocated turret & two relocated gates.
