Marugame Castle

Marugame Castle, located in the city of Marugame in Japan, is a remarkable example of a hill castle that combines strategic military architecture with stunning natural topography. Built originally in 1597 during the late Sengoku period, this castle has a rich history tied to the feudal lords who ruled the Sanuki region. Its preservation and unique features make it a significant cultural and historical site in Japan.

Historical background and significance

The castle was initially constructed by Ikoma Chikamasa, the lord of the Sanuki area, who originally ruled from Takamatsu Castle. Seeking a more defensible position, he built Marugame Castle on a hill, which allowed for better surveillance and control over the surrounding territory. After establishing Marugame Castle, he placed his son in charge of Takamatsu Castle, effectively shifting the center of power.

In 1615, the castle was decommissioned due to the "one castle per domain" law (Ikkoku Ichijo Rei) imposed by the Tokugawa shogunate, which aimed to reduce the number of castles to prevent rebellion and consolidate power. This law required many castles to be dismantled or abandoned, including Marugame Castle.

However, Marugame Castle experienced a revival in 1641 when Yamazaki Ieharu was granted the small fief of Western Sanuki. He undertook significant reconstruction efforts, rebuilding the castle into the form that largely remains today. Under his stewardship, the castle town of Marugame also developed, growing around the castle's base and benefiting from its protection and administrative functions.

Architectural features and castle layout

Marugame Castle is renowned for its magnificent stone walls, which are among the best-preserved and most impressive in Japan. Unlike the large Edo-period castles such as Edo, Osaka, or Nagoya, where the stone walls are often separated from visitors by moats, Marugame Castle allows close proximity to these walls, enhancing the visitor experience and appreciation of their scale and craftsmanship.

The castle is built on the only mountain in the vicinity, providing a commanding view over the surrounding plains and the Seto Inland Sea. This strategic location made it an important military stronghold and a symbol of feudal power.

One of the most notable features of Marugame Castle is its main keep (tenshu), which is the smallest surviving main keep in Japan. Despite its modest size, the keep's elevated position atop the hill offers an extensive vantage point, rendering a large keep unnecessary for effective defense and surveillance.

The castle complex includes multiple baileys, gates, and defensive walls, all carefully designed to maximize protection while integrating harmoniously with the natural landscape. The stone walls demonstrate advanced masonry techniques of the period, with carefully fitted stones that have withstood centuries of weather and seismic activity.

The stone walls and masonry

The stone walls of Marugame Castle are particularly famous for their size and quality. They were constructed using a method called nozura-zumi, which involves stacking unshaped stones without mortar, relying on the careful placement and weight of the stones for stability. This technique creates a naturalistic and durable structure that blends seamlessly with the surrounding environment.

Visitors can walk close to these walls, appreciating the craftsmanship and scale that is often lost in other castles where moats or modern barriers keep visitors at a distance.

Castle town and cultural heritage

The development of the castle town of Marugame was closely linked to the castle's reconstruction in the mid-17th century. The town grew as a center of administration, commerce, and culture under the protection of the castle. It retains many historical buildings and streetscapes that reflect its Edo-period origins.

Today, Marugame Castle stands not only as a military relic but also as a cultural landmark. It hosts various events and festivals that celebrate its history and the traditions of the region. The castle and its grounds are a popular destination for tourists and scholars interested in Japanese feudal architecture and history.
