Japan’s Tallest Castle Walls: Over 60 Meters of Magnificent Stonework

Marugame Castle and its stone walls surrounded by lush greenery. The elevation difference up to the main keep is clearly visible.

One of Marugame Castle’s defining features is its massive stone walls that rise from the Otemon Gate area at the foot of the hill all the way to the main keep. The total elevation reaches over 60 meters, making it the tallest among all existing castles in Japan.

At its highest point, the stone wall itself is approximately 20 meters tall. Its imposing structure overwhelms anyone who gazes up from the base.

Various masonry techniques are showcased throughout the site, with dressed-stone methods such as uchikomi hagi and kirikomi hagi being the most prominent. You can also spot examples of nozurazumi (unshaped stone stacking) and sangizumi (corner-stone technique) in different locations.

Notable features include engraved stones, the precise interlocking of corner stones, and the gentle curvature known as the “fan slope” (ogi no kobai) seen in the upper portions—evidence of craftsmanship and aesthetic intent.

Located at the entrance to the sannomaru (third enclosure), the gate is surrounded by thick stone walls and was built with a robust defensive design. The upper level of the gate once served as a watchtower, equipped with features to repel intruders from above.

The gate is also known as the “Taiko-mon” (Drum Gate), named after the custom of samurai striking a drum at noon to mark the time. Today, visitors can experience this tradition by applying at the tourist information center by 11:50 a.m. to participate in the noon drum performance (free of charge).

Marugame Castle’s Notorious Steep Slope: The Dizzying Mikaeri-zaka

One of the most memorable parts of the ascent to Marugame Castle is the Mikaeri-zaka, or “Look-Back Slope.” This name comes from the fact that many visitors can’t help but look back repeatedly while climbing the steep hill—measuring about 150 meters in length with an incline exceeding 10 degrees.

The starting point of Mikaeri-zaka, Marugame Castle’s uphill stone-paved path. The slope begins gently.

Climbing it is no easy task. We recommend taking your time and resting along the way. One look back, and you’ll see just how steep it truly is.

Be aware that Mikaeri-zaka is actually split into two sections. Knowing this beforehand may spare you from despair during the climb. If this article saved you from that shock, then it’s already served its purpose.

Once you reach the top, you’ll find the sannomaru, where the scenery opens up dramatically. Enjoy the rewarding views and the sight of the original keep—conquering Mikaeri-zaka is well worth it.

History of Marugame Castle: From Feudal Rule to Modern Preservation

Marugame Castle’s origins trace back to 1597 (Keichō 2), when it was built on Mt. Kameyama by Ikoma Chikamasa and his son Kazumasa—retainers of Toyotomi Hideyoshi. The castle and its surrounding town were constructed in a fully fortified style, using moats and embankments to demonstrate both authority and defense.

In 1615 (Genwa 1), the One Castle per Province Law led to its initial abandonment. However, in 1641 (Kan’ei 18), Yamazaki Ieharu became lord of the Marugame Domain and began reconstruction. The Kyōgoku family took over in 1658 (Manji 1), and by 1660 (Manji 3), the current three-tiered keep was completed. Around 1670 (Kanbun 10), the present Otemon Gate and other structures were built.

During the Meiji Restoration, much of the castle was scheduled for demolition in 1872 (Meiji 5), but the keep and gate were preserved. In 1919 (Taisho 8), the area was opened to the public as Kameyama Park. The keep was designated an Important Cultural Property in 1950, followed by the gate in 1957.
