Minakuchi Castle Ruins is a historic site located in Koka City, Shiga Prefecture. It holds a significant place in history as a lodging built for the third Shogun of the Edo Bakufu, Tokugawa Iemitsu, during his visits to Kyoto. Due to its use of natural spring water in its moats, it was also known as 'Hekisui-jo' (Azure Water Castle). Currently, the site is open as the Minakuchi Castle Museum, featuring a reconstructed 'Sumiyagura' (corner tower) that mimics the original architecture. The sight of the white-walled structure reflecting on the surface of the water is an iconic and breathtaking view of this location.
In the early Edo period, this site was developed as a lodging for the Shogun and later became the seat of the Minakuchi Domain (25,000 koku). Following the Meiji Restoration, many structures were lost; some corner towers were sold to local merchants, and parts of the stone walls were even used as paving stones for the Ohmi Railway. However, in 1972, the site's historical value as a Shogun's lodging was officially recognized, and it was designated as a historical site of Shiga Prefecture. Today, it is carefully preserved as a local symbol of history.
The museum displays a variety of precious historical materials regarding Minakuchi Castle. A particularly notable exhibit is the 'Minakuchi Rapier,' introduced in April 2023. This is a model of a cross-shaped Western sword associated with Kato Yoshiaki (one of the Seven Spears of Shizugatake), the founder of the Minakuchi Domain, and is held by Toei Shrine. Additionally, the reconstructed corner tower and the scenic view of the moats fed by natural springs provide a vivid visual connection to the castle's former grandeur.
Minakuchi Castle Ruins offers different charms depending on the season. In spring, the area is particularly stunning as the surrounding cherry blossoms reach full bloom, painting the landscape around the water. The sight of cherry blossoms reflecting on the moat is a quintessential Japanese spring scene. For the best experience, we recommend visiting during daylight hours (between 10:00 and 17:00) to enjoy the striking contrast between the white walls of the tower and the blue sky.
Visitors can learn about the castle culture of the Edo period through historical artifacts and models. The 'Minakuchi Rapier' exhibit offers a fascinating window into the history and culture of the samurai class. The museum's layout is designed to provide a deep understanding of the role the castle played as both a Shogun's lodging and the center of the Minakuchi Domain.
The area surrounding the Minakuchi Castle Ruins retains a charming, historical atmosphere. Being close to the Ohmi Railway station, it is easy to explore the area on foot while soaking in the historical streetscapes of Koka City. The surrounding environment is rich in nature, offering a peaceful time spent by the water.
