Complete Guide to the Otomo Clan Residence (Oita Prefecture) | A National Historic Site that Conveys the Glory of a Sengoku Daimyo
Located in the heart of Oita City, Oita Prefecture, the Otomo Clan Residence is the site of the residence of the Otomo clan, who ruled the entire northern Kyushu region during the Sengoku period. Designated a national historic site in 2001, recent excavations and restoration work are bringing the site back to life. This article comprehensively covers everything you need to know before visiting, from the history of the Otomo Clan Residence to its highlights and access information.
Overview of the Otomo Clan Residence Site
The Otomo Clan Residence Site is a medieval archaeological site spread across the area of 3-2-45 Kentoku-cho, Oita City, Oita Prefecture. Its official name is “Otomo Clan Ruins,” registered as a national historic site, and it refers to a vast group of ruins centered around the Otomo Clan Residence (Otomo-kan).
Location and Scale
The Otomo Clan Residence was located in the Kentoku-cho area near the mouth of the Oita River. At its peak, the mansion measured approximately 200 meters east-west and 200 meters north-south, making it one of the largest residences of a Sengoku period daimyo (feudal lord). Archaeological excavations have revealed that a square area of approximately 100 meters on each side was located in the center of the mansion, with a magnificent garden situated to its south.
Historical Background
The area where the Otomo clan mansion was built was known as Bungo Fuchu or Funai, and was the political, economic, and cultural center of Bungo Province from the medieval to the early modern period. The Otomo clan established their provincial headquarters here during the Kamakura and Muromachi periods. Especially in the 16th century during the Sengoku period, it flourished as an international city with a population of tens of thousands, serving as a hub for trade with the Nanban (Southern Barbarians).
History of the Otomo Clan Mansion
From Founding to Development
While there are various theories regarding the founding date of the Otomo clan mansion, the most widely accepted theory is that it was built during the time of the 10th head of the family, Otomo Chikayo. Subsequently, the Otomo clan, who expanded their power as a shugo daimyo (provincial governor), repeatedly renovated and expanded their residence.
From the late 14th to the 15th century, the Otomo clan established a firm position as the shugo of Bungo Province. During this period, the residence served not only as a place for conducting political affairs but also as a military base for commanding their retainers.
The Era of Otomo Sorin and the Peak Period
The Otomo clan residence flourished most during the time of the 21st head of the family, Otomo Sorin (Yoshishige). From the 1550s to the 1570s, Sorin controlled most of northern Kyushu and developed Bungo Funai into a major center of Nanban trade (trade with European countries).
Around 1573, when Sorin handed over the family headship to the 22nd head, Yoshimune, the residence was renovated to its largest size, measuring 200 meters east-west and 200 meters north-south. During this period, Japan’s first Western-style hospital and a college (seminary) were established in Funai, and Christian culture flourished.
Construction and Renovation of the Garden
The garden remains discovered during the 1998 (Heisei 10) excavation are important relics that attest to the high cultural level of the Otomo clan residence. Research revealed that the garden was built approximately 500 years ago, during the time of the 19th head of the clan, Yoshinaga.
Later, in the late 16th century, during the time of Sorin and Yoshimune, the garden underwent a large-scale renovation, transforming into a style featuring a magnificent pond. This garden possessed the formality and aesthetic sense befitting a Sengoku daimyo’s residence and was a symbolic representation of the Otomo clan’s power at the time.
Invasion and Decline of the Shimazu Clan
The prosperity of the Otomo clan residence came to an end in 1586 (Tensho 14). When Shimazu Iehisa of Satsuma invaded Bungo, the town of Funai was burned down, and the Otomo clan’s residence also suffered extensive damage. This “Bungo-Satsuma War” led to a rapid decline in the Otomo clan’s power.
Although Sorin had already moved his base to Niujima Castle (Usuki Castle), the burning of Funai symbolized the decline of the Otomo clan’s authority. Later, the Otomo clan temporarily recovered their territory during Toyotomi Hideyoshi’s conquest of Kyushu, but after the Battle of Sekigahara, they were dispossessed of their lands, bringing their history as a Sengoku daimyo to an end.
About Uehara Residence (Ueno Residence)
Besides the Otomo clan’s residence in Kentoku-cho, there was another Otomo residence within Oita City. This was the “Uehara Residence.”
Location and Characteristics of Uehara Residence
Uehara Residence was located on the north side of the Ueno Plateau, in what is now Ueno, Oita City. Located on a plateau surrounded by lush greenery, it was strategically situated to overlook the medieval town of Funai. Historical records refer to it as “Uehara-kan,” and it is believed to have served a different role than the Kentoku-cho residence.
Relationship between the two residences
Research is ongoing regarding the relationship between the Kentoku-cho residence and Uehara-kan. Possible uses include being used interchangeably depending on the period, or being used for different purposes (such as administrative and residential). Further archaeological excavations are needed to understand the detailed structure and scale of Uehara-kan.
Connection to the former Manju-ji Temple site
The area surrounding the Otomo clan residence site also includes the former Manju-ji Temple site. Manju-ji Temple had deep ties to the Otomo clan and is an important site for understanding the religious and cultural aspects of the residence.
The Otomo clan were also patrons of Buddhist temples, and are known to have had particularly close ties with Zen temples. Investigations at the Manju-ji Temple site are revealing the structure of a medieval city where the residence and temple were integrated.
Restored Garden at the Otomo Clan Residence Site
Currently, the garden at the Otomo Clan Residence Site is being restored and maintained based on the results of archaeological excavations. This garden recreates the appearance of the garden during the time of Sorin and Yoshimune, allowing visitors to experience the aesthetic sensibilities of a Sengoku-era daimyo from approximately 500 years ago.
Garden Structure and Features
The restored garden is a pond garden centered around a magnificent pond. Stone arrangements surround the pond, demonstrating the high level of garden design techniques of the time. Seasonal flowering trees and shrubs are planted in the garden, allowing visitors to enjoy different scenery throughout the year.
Cherry blossoms in spring, fresh greenery in early summer, and autumn leaves in fall—beautiful scenery awaits visitors throughout the year. The garden’s design aims to faithfully reproduce its appearance as much as possible, based on a detailed analysis of medieval drawings and excavated remains.
Garden Highlights
The garden’s greatest highlight is the arrangement of the stonework and pond, which conveys the garden design style of the Sengoku period to the present day. The shape of the pond and the arrangement of the stones are based on the remains confirmed during archaeological excavations, making it a valuable example of archaeological reconstruction.
Furthermore, the garden allows visitors to experience the spatial composition including the surrounding landscape. The Otomo clan residence at the time featured a comprehensive spatial design, including the garden, functioning as a device to demonstrate the authority and cultural sophistication of a Sengoku-period daimyo.
Nanban BVNGO Exchange Center
Adjacent to the Otomo Clan Residence Garden, the Nanban BVNGO Exchange Center, which opened in 2020, is an exhibition facility introducing the achievements of Otomo Sorin and the history of Bungo Funai.
Exhibition Contents
The Nanban BVNGO Exchange Center introduces the era of the Otomo clan from multiple perspectives, including the life of Otomo Sorin, the realities of Nanban trade, and the acceptance of Christian culture. Through powerful video exhibits, reconstructed models, and excavated artifacts, visitors can experience the appearance of Bungo Funai during the Sengoku period.
The exhibits on Nanban trade are particularly noteworthy. The exhibit provides a detailed explanation of the Western artifacts, technologies, and influence of Christian culture brought to Funai through trade with Portugal and Spain.
Video Experience
The exchange hall also features exhibits utilizing the latest video technology. Videos recreating the Otomo clan’s residence in its heyday using CGI, and documentary films tracing the life of Sorin are shown, deepening understanding of history.
Archaeological Findings
Since 1998, continuous archaeological excavations have been conducted at the Otomo clan residence site. These investigations have gradually revealed the structure and changes of the residence, as well as the lifestyle of the time.
Major Discoveries
The excavations have confirmed the foundation stones of the residence, the remains of stone walls, the remains of moats, and garden structures. A particularly important discovery was the remains of a large-scale pond garden from the late 16th century. This garden is a rare example of a Sengoku-period daimyo’s residence garden nationwide.
Furthermore, the excavated artifacts have shed light on the realities of the Nanban trade (trade with the West). Numerous artifacts with a rich international character have been discovered, including Chinese porcelain, Southeast Asian pottery, and European glassware.
Archaeological Value
The excavation of the Otomo clan residence site holds a significant position in the study of residences of shugo daimyo and sengoku daimyo during the Sengoku period. The size, structure, and garden style of the residence provide valuable information for understanding the reality of daimyo power at the time.
In particular, the discovery of artifacts indicating connections to Nanban trade and Christian culture provides important evidence of the exchange between Japan and the world in the 16th century.
The Otomo Clan and Nanban Trade
During the time of Otomo Sorin, Bungo Funai flourished as a major center of Nanban trade. The impact of this international exchange on the Otomo clan residence and the town of Funai is immeasurable.
Funai as an International City
With the arrival of Portuguese ships, foreign merchants and missionaries began to stay in Funai. The town grew to a population of tens of thousands, and Western-style hospitals, seminaries, and churches were built.
Sorin himself showed a deep interest in Christianity, and in 1578 he was baptized, receiving the baptismal name Don Francisco. This policy of protecting Christianity made Funai one of the centers of Christian culture in Japan.
Cultural Influence
The Nanban trade and the acceptance of Christian culture also influenced the cultural character of the Otomo clan’s residence. It has been suggested that Western architectural techniques and garden styles may have been incorporated, and archaeological excavations continue to search for traces of this.
