Hitachi Matsuyama Castle
A mountain castle in Kasama, Ibaraki, held by the Kasama clan for generations. Its position on a forested ridge above the ancient castle town features well-preserved stone walls and earthworks. The adjacent Kasama Inari Shrine, Japan's oldest Inari shrine, makes this a doubly historic site.

Hitachi Matsuyama Castle is a fourteenth-century mountain fortress located in Kasama, Ibaraki Prefecture, representing an important chapter in the history of the Kanto region. The castle was held by the Kasama clan for generations, serving as their power base in central Japan. This site is listed among Japan's 100 Famous Castles and remains one of the most historically significant ruins in the Kanto area.
The castle's origins trace back to the medieval period when the Kasama clan established themselves as a regional power. Over centuries, they maintained and strengthened the fortress, adapting its defenses to the changing military technology and political circumstances of their time. The castle served as both a military stronghold and an administrative center for the surrounding territories, playing a key role in the balance of power among regional daimyo.
Positioned on a forested ridge above the ancient castle town, the site features remarkably well-preserved stone walls and earthworks that testify to careful construction and maintenance. The natural topography of the mountain provided excellent defensive capabilities, with slopes that would have made direct assault extremely difficult. The adjacent Kasama Inari Shrine, recognized as Japan's oldest Inari shrine, adds additional historical depth to the location, creating a dual heritage site that combines religious and military significance.
Visitors to the ruins can walk through the reconstructed fortifications and gain a sense of the castle's former strategic importance. The forested setting and combination of archaeological remains and religious architecture offer a comprehensive view of medieval Kasama's cultural landscape. The site remains an important destination for those researching feudal Kanto history and Japanese castle architecture.
Hitachi Matsuyama Castle is recognized as one of Japan's second 100 castles as designated by the Japan Castle Foundation, a distinction that highlights its historical and architectural importance among the hundreds of castle sites across the country. As a mountain castle, its design reflects the defensive priorities and construction techniques of its era, with origins dating to 14th c. Visitors traveling to Ibaraki Prefecture can explore the site alongside other regional historical attractions.

Is It Original?
| Original keep still standing? | No — this castle is not among the twelve in Japan whose keep survives from the pre-modern period. Any tower here is a later reconstruction or the site is a ruin. |

The count of twelve surviving keeps is stated independently by the official sites of Matsue, Maruoka, Matsuyama and Bitchu Matsuyama (checked 2026-09-04). Each of the twelve carries its own source on its own page. The classification line below it is this site's own grouping, not an official designation. The designated properties below it come from the Agency for Cultural Affairs national database of designated cultural properties (国指定文化財等データベース), retrieved 2026-08-13. A missing line means no entry was found in that database — not that the property is undesignated.
