Also known as “Fujigamori Castle,” the remains of the main keep and second bailey, including earthworks, moats, and dry moats, are still well-preserved. This article provides a detailed explanation of Harada Castle, from its historical background to its structure, highlights, and access methods.

History of Harada Castle

Relationship between the Harada Clan and the Date Family

The Harada clan is known as hereditary retainers who served the Date clan from the time of Date Tomomune, the first head of the Date clan. As the Date family expanded its power into Oshu, the Harada clan was entrusted with governing the Okitama region and built a castle in this area. The Harada clan held an important position within the Date family as senior retainers, contributing to the family’s development for generations.

Construction and Development of Harada Castle

While there are no clear records of when Harada Castle was built, it is believed to have been constructed during the medieval period when the Date clan consolidated its power in the Okitama region. The castle was built on a hill called Fujigamori, utilizing its natural fortifications surrounded by cliffs on three sides, and was developed as a flatland castle.

The Harada clan used Harada Castle as their base to govern the surrounding area and also focused on developing the castle town. In particular, they contributed to the cultural development of the region, including founding Toyoji Temple, their family temple.

Harada Samanosuke Munetoki and the Castle’s Abandonment

The last lord of Harada Castle was Harada Samanosuke Munetoki (Harada Samanosuke Munetoki). Munetoki was a senior retainer who served Date Masamune and was one of the figures who supported Masamune during his time in Yonezawa.

In 1591 (Tensho 19), when Date Masamune was transferred from Yonezawa to Iwadeyama Castle (present-day Osaki City, Miyagi Prefecture) by order of Toyotomi Hideyoshi, Harada Munetoki also moved with him. This transfer resulted in the abandonment of Harada Castle, bringing an end to approximately 400 years of Harada clan rule over Okitama.

Relationship with Harada Kai Munesuke

Harada Samanosuke Munetoki was the grandfather of Harada Kai Munesuke, known for his role in the “Date Disturbance” that occurred in the early Edo period. Harada Kai Munesuke served the Sendai Domain as a vassal of the Date family and left his mark on history as a central figure in the Kanbun Incident (Date Disturbance). The fact that Munetoki, Munesuke’s grandfather, was the last lord of Harada Castle is an important fact when discussing the history of the Harada family.

Structure and Characteristics of Harada Castle

Castle Scale and Layout

Harada Castle is a flatland castle measuring approximately 350 meters east-west and 100 meters north-south. The castle consists of two baileys, the west side being the main bailey (Honmaru) and the east side the second bailey (Ninokuruwa). These two baileys are clearly separated by a moat, exhibiting a typical structure of a medieval castle.

The main gate (Ote) is located on the south side, and the castle’s layout, taking advantage of the terrain surrounded by cliffs on three sides, provides a highly defensible design. This location made enemy intrusion difficult and was designed to be easily defended even with a small force.

Remains of the Main Bailey

The main bailey, located on the west side, is the core of the castle. A portion of the earthen rampart remains facing the moat on the west side of the main bailey, conveying the appearance of the defensive facilities at the time. Ancient fir trees stand tall at the site of the main bailey, creating a historical atmosphere at the castle ruins.

Remains of the Main Bailey

The main bailey, located on the west side, is the core bailey of the castle. The earthworks of the main keep are covered in moss, giving a sense of the long history of the castle ruins. The height and shape of the earthworks offer insights into the castle construction techniques and defensive philosophies of the time.

The Second Bailey and the Site of Shinzei Sojo’s Meditation

On the eastern side, in the second bailey, stands a five-tiered pagoda marking the “site of Shinzei Sojo’s meditation.” Shinzei Sojo was a high-ranking priest of the Heian period, and it is said that he entered meditation at this site. The five-tiered pagoda is an important relic demonstrating medieval religious beliefs, indicating that Harada Castle was not merely a military facility but also a place of religious significance.

Like the main keep, the second bailey is separated by a dry moat and functioned as an independent defensive unit. This structure is thought to have been designed so that resistance could continue in the second bailey even if the main keep were to fall.

Moats and Dry Moats

One of the most prominent remains of Harada Castle is the moat. The moat separating the main keep and the second bailey can still be clearly seen today. The moat, dug to cut across the ridge, played a crucial role in preventing enemy incursions.

A dry moat also surrounded the castle, its scale suggesting the power and advanced castle-building techniques of the Harada clan. These remains are documented in detail in the Yamagata Prefectural Board of Education’s “Yamagata Prefecture Medieval Castle Site Survey Report, Volume 1 (Okitama Region).”

Highlights of Harada Castle

Well-Preserved Earthworks and Moats

The greatest attraction of visiting Harada Castle is the opportunity to directly observe the well-preserved remains of a medieval castle. The earthworks and moats, in particular, remain clearly visible, making them unmissable points for castle enthusiasts. The moss-covered earthworks blend seamlessly with nature, conveying a sense of historical weight.

Walking through the moat, one can experience its function as a defensive structure through its depth and width. It’s also enjoyable to imagine what the medieval samurai were trying to protect in this place while strolling through the moat.

Ancient Fir Tree and Historical Landscape

The ancient fir tree towering over the site of the main keep is a symbolic presence of Harada Castle. This giant tree has watched over the castle for over 400 years since its abandonment. Standing around the ancient tree, one can feel the passage of time from the medieval period to the early modern period and into the present day.

The entire castle site is covered in forest, allowing visitors to enjoy the beauty of nature throughout the seasons. Especially during the seasons of fresh greenery and autumn leaves, a beautiful scene unfolds where the historical landscape and natural beauty harmonize.

The Site of Shinzei Sojo’s Passing

The five-tiered pagoda in the second bailey is a historically interesting relic. Shinzei Sojo was a high-ranking priest of the Heian period and is considered a figure who contributed to the development of Buddhist culture in the Tohoku region. The fact that this site was chosen as his place of passing suggests that this place has been recognized as a sacred site since ancient times.

The area around the five-tiered pagoda is enveloped in a tranquil atmosphere, a space where history and faith intersect.

Views Overlooking the Okitama Basin

Because Harada Castle is built on a hillside, the castle ruins offer panoramic views of the Okitama Basin. This view, overlooking the territory once ruled by the Harada clan, is a precious opportunity to relive the scenery seen by the feudal lords of the Sengoku period.
