Marugame Castle boasts stone walls with a total height exceeding 60 meters from the base of the main gate to the main enclosure—the tallest among all existing castles in Japan.

The stone walls reach approximately 20 meters at their highest point, presenting an overwhelming presence when viewed from below.

The stone walls feature various techniques depending on the level of stone processing, including uchikomi-hagi and kirikomi-hagi as primary methods, with nozurazumi and sangi-zumi visible in the same location.

Details such as stones with carved marks, neatly arranged sangi-zumi stacking, and the gentle curve known as “fan slope” that becomes more pronounced toward the top showcase the craftsmanship and design sensibility of the builders.

The tower of Marugame Castle is one of the “Twelve Original Castle Towers” that have survived from the Edo period in their original form.

While the watchtowers themselves no longer exist, their former sites have been developed as observation decks offering views of Marugame city, the Seto Inland Sea, and Mount Iinoyama, affectionately known as Sanuki Fuji. The expansive views exceed expectations—truly capturing the essence of a castle built on a mountain.

Ote-ichi-no-mon, the main gate of Marugame Castle, is a wooden turret gate built around 1670 (Kanbun 10) and is one of the few surviving Edo-period castle gate structures. It is designated as an Important Cultural Property of Japan.

This gate is located at the entrance to the Sannomaru area, characterized by its robust structure surrounded by thick stone walls. The upper portion is a two-story turret designed with defensive capabilities to attack intruders from above.

It is also called the “Drum Gate” because domain retainers would beat a drum at noon to announce the time. Even today, visitors can participate in a drum-beating experience (free) by registering at the tourist information center by 11:50 on the day.

A Marugame Castle Signature: The Incredibly Steep “Mikaeri-zaka” Slope

The most memorable feature of the approach to Marugame Castle is Mikaeri-zaka (Looking Back Slope). Approximately 150 meters long with a gradient over 10 degrees, this steep uphill climb earned its name because many climbers literally look back as they ascend.

Walking it firsthand proves quite challenging. We recommend taking it slowly with rest breaks. Looking back reveals just how steep it really is.

Just when you think you’ve made it, another steep section awaits.

Knowing beforehand that Mikaeri-zaka is divided into two sections can save you from despair on-site. Perhaps learning this alone makes reading this article worthwhile.

However, reaching the top rewards you with the Sannomaru area and suddenly expansive views. Keep the spectacular scenery and original castle tower in mind as motivation to conquer Mikaeri-zaka.

During the cherry blossom festival (typically March 25 to April 10), evening illuminations light up the stone walls and tree-lined paths with paper lanterns and decorative lights. The “Sea of Cherry Blossoms” illumination in the Ninomaru area is particularly popular for its dreamlike view of flowers and lights spreading below.

From autumn through winter, an annual illumination event called “Marugame Castle Castle Road” takes place. The approach path and stone walls from the main gate to the tower are adorned with lights, projection mappings illuminate the masugata stone walls and Ote-ichi-no-mon Gate, and Mikaeri-zaka transforms into a tunnel of light—creating an enchanting castle landscape entirely different from daytime.

History of Marugame Castle: From Feudal Era to Modern Times

The history of Marugame Castle begins in 1597 (Keicho 2) when Ikoma Chikamasa and his son Kazumasa, retainers of Toyotomi Hideyoshi, built the castle on Kameyama (Marugame). A “sogamae” (comprehensive defense) design was adopted, enclosing the castle and castle town with earthworks and moats—a structure demonstrating the authority and defensive power of the era.

Later, following the One Castle Per Province Law in 1615 (Genna 1), the castle was once abandoned. In 1641 (Kan’ei 18), Yamazaki Ieharu was transferred as lord of Marugame Domain and began reconstruction. In 1658 (Manji 1), the Kyogoku family took over, and in 1660 (Manji 3), the existing three-story, three-floor tower was completed, with the current main gate location and other structures being built around 1670 (Kanbun 10).

After the Meiji Restoration in 1872 (Meiji 5), most of the castle was scheduled for demolition, but the tower and gates were preserved. In 1919 (Taisho 8), it was opened as Kameyama Park, and in 1950 the tower, followed by the main gate in 1957, were designated as Important Cultural Properties.
