What is Karaume-date? | Historical Heritage of Ichinoseki City, Iwate Prefecture
Karaume-date is a mountain castle built on the summit of Mt. Karaume (249.6m above sea level), also officially known as “Nagasaka Castle.” This area functioned as an important military base in the Tohoku region from the late Heian period to the Sengoku period.
Currently, it has been developed as “Karaume-date Comprehensive Park,” preserving historical remains while providing a place of relaxation for citizens with sports and recreation facilities. Located in the heart of Higashiyama-cho, Ichinoseki City, it is known as an important tourist spot that conveys the history and culture of the region.
The History of Karaume-kan | From the Heian Period to the Sengoku Period
Heian Period: The Era of the Fujiwara Clan and Terui Taro
The history of Karaume-kan dates back to the Heian period. During the time of the Oshu Fujiwara clan, it is believed that Terui Taro, a chief retainer of Fujiwara Hidehira, established his residence in this area. It is said that what was originally called “Karou-ga-date” (Chief Retainer’s Residence) gradually changed to “Karaume-kan” over time.
During this period, Karaume-kan played an important role as a strategic point in the Kitakami River basin within the sphere of influence of the Oshu Fujiwara clan, centered around Hiraizumi.
Medieval Period: Rule of the Kasai Clan and the Chiba Family
After the fall of the Fujiwara clan, from the Kamakura period to the Sengoku period, this region came under the rule of the Kasai clan. Among the Chiba family, who were subordinates of the Kasai clan, the Nagasaka Chiba clan ruled from Karaume-kan as their base for approximately 400 years.
The Nagasaka Chiba clan, as the head family of the Chiba-named generals who wielded power within the Kasai territory, were a central figure in the region’s politics and military affairs. The Karabaikan was strategically important as the Chiba clan’s base for defending their territory.
The Fateful Military Council of 1590
The most famous episode in the history of the Karabaikan is the military council held in 1590. In March of that year, the Chiba clan received notification from Toyotomi Hideyoshi to participate in the Odawara campaign. On April 17th of the following year, they gathered at the Karabaikan and faced a crucial decision.
At this historical turning point—whether or not to obey Hideyoshi’s orders—the Chiba clan decided against it. This decision had a significant impact on the subsequent history of the Tohoku region. Currently, an event recreating this historical moment, the “Karabaikan Emaki” (Karabaikan Picture Scroll), is held annually and has become an important cultural event in the region.
Structure of Karaume Castle Ruins | Characteristics and Remains of a Mountain Castle
Topographical Features and Defensive Structure
Karamume Castle Ruins is a typical mountain castle built on a natural stronghold surrounded by rivers on three sides: east, west, and south. Its location on the summit of Mt. Karaume, at an altitude of 249.6m, provided advantageous conditions for defense, allowing for early detection of approaching enemies.
Main Enclosure and Enclosure Layout
The main enclosure, located on the mountaintop, measures approximately 50m east-west and 30m north-south. A rampart approximately 1m high runs from the north to the west side of the main enclosure, a trace of the original defensive structure that can still be seen today.
Several tiers of lower enclosures (koshiguruma) were arranged on the east and south sides, forming a stepped defensive line. These remains are valuable historical documents illustrating the mountain castle construction techniques of the Sengoku period.
Existing Remains
Even today, the remains of the mountain castle, such as earthworks, baileys, and moats, remain, making it a valuable subject for historical walks and castle research. Even now, as a park, these historical remains are preserved as much as possible, and care is taken to allow visitors to experience the atmosphere of the Sengoku period.
