Located in Nichinan City, Miyazaki Prefecture, Obi Castle is a historic castle that flourished for approximately 280 years during the Edo period as the administrative center of the Ito clan’s 51,000-koku domain. Selected as one of Japan’s 100 Famous Castles, its beautiful stone walls made of Obi stone and the castle town with its remaining samurai residences are affectionately known as “Kyushu’s Little Kyoto.” This article provides a detailed explanation of Obi Castle, from its history to its highlights and tourist information.
What is Obi Castle? | A Representative Historical Spot in Miyazaki Prefecture
Obi Castle was a Japanese castle located in Obi, Nichinan City, Miyazaki Prefecture (southern part of the former Hyuga Province). It is a flatland castle built in a cluster-style layout, skillfully utilizing the topography of the Shirasu plateau on the north bank of the Sakatani River. During the Edo period, it functioned as the administrative center of the Ito clan’s Obi Domain and developed as a center of politics, economy, and culture. Currently, the castle ruins are maintained as the Obi Castle Site, and visitors are captivated by the stone walls and samurai residences that retain a strong atmosphere of the time, including the Obi Castle Otemon Gate, which was restored in 1978. The fact that the entire castle town was designated as an Important Preservation District for Groups of Traditional Buildings in 1977, the first such designation in the Kyushu region, speaks to its high historical value.
History of Obi Castle | The Battles Between the Ito and Shimazu Clans
Construction During the Nanboku-cho Period
The origins of Obi Castle date back to the Nanboku-cho period. It is believed to have been originally built by the Tsuchimochi clan, who held power in Hyuga Province. At that time, Obi was a strategically important location as a key point in southern Hyuga Province.
The Fierce Struggle Between the Ito and Shimazu Clans
An essential part of understanding the history of Obi Castle is the fierce struggle between the Ito and Shimazu clans that lasted for approximately 100 years. The two clans repeatedly attacked and fought for control of Obi Castle. During this time, ownership of the castle changed hands so frequently that the saying “Obi’s castles: 48 Ito, 48 Shimazu” reflects the intense competition between the two clans.
During the Sengoku period, the Ito clan held a temporary advantage, but suffered a crushing defeat at the hands of Shimazu Yoshihiro at the Battle of Kizakihara in 1577 (Tensho 5), forcing the Ito clan to flee to Bungo (present-day Oita Prefecture).
The Ito Clan’s Entry into Obi and the Establishment of Domain Administration
A turning point came after Toyotomi Hideyoshi’s conquest of Kyushu. In 1587 (Tensho 15), Ito Suketake was granted permission to enter Obi Castle by order of Toyotomi Hideyoshi. The following year, 1588 (Tensho 16), he officially became the lord of Obi Castle, and from then until the Meiji Restoration, the Ito clan ruled the domain for approximately 280 years.
Throughout the Edo period, the Obi Domain remained stable as a large, tozama (outside) domain with a 51,000 koku (unit of rice production) yield, and the castle town prospered as a center of politics, economy, and culture. In particular, the forestry of Obi cedar and the shipping industry flourished, supporting the domain’s finances.
Obi Castle After the Meiji Restoration
After the Meiji Restoration, the Obi Domain was abolished due to the abolition of the feudal system and the establishment of prefectures, and many of the castle’s structures were demolished. However, remnants such as stone walls and moats remain, and efforts are being made to preserve and utilize the historical landscape, such as the restoration of the Obi Castle Otemon (main gate) in 1978.
Structure and Features of Obi Castle | The Charm of a Group-Style Hilltop Castle
Layout Utilizing the Shirasu Plateau
Obi Castle is a hilltop castle built on a Shirasu plateau at an altitude of approximately 50 meters on the north bank of the Sakatani River. It employs a group-style layout, characterized by a structure where multiple baileys (kuruma) are arranged in parallel around the main bailey (honmaru). This arrangement effectively prevented enemy incursions.
The main baileys included the honmaru, ninomaru, sannomaru, Nakanoshiro, and Matsuo-no-maru, each separated by moats and stone walls. No keep was built; the lord’s residence was located in the honmaru.
Beautiful Stone Walls Made with Obi Stone
One of the major highlights of Obi Castle is its stone walls, made using Obi stone. Obi stone is a locally produced sandstone that is easy to process and highly durable. The stone walls, constructed using techniques such as rough-hewn stonework and fitted stonework, retain their beautiful appearance even after more than 400 years.
The stone walls around the main gate and the former main keep site are particularly well-preserved, demonstrating the high level of castle-building technology of the time. The moss-covered stone walls display different expressions in each season, captivating visitors.
Landscape Adorned with Obi Cedar
Many Obi cedars are planted within the castle grounds and the castle town. Obi cedars were an important industrial resource for the Obi domain and supported its finances. The rows of straight-growing Obi cedars further enhance the atmosphere of the castle town.

Inside, the lord’s living room, study, and kitchen are recreated, and furnishings and daily necessities are on display. The Japanese garden viewed from the tatami rooms displays beauty in every season, especially during the autumn foliage season. Furthermore, at Matsuo-no-Maru, you may even have the opportunity to try on a kimono, allowing you to experience the Edo period even more deeply.
Former Main Enclosure Site
The former main enclosure site is the central area of Obi Castle, where the lord’s residence and government offices once stood. Currently, it is a plaza, and the surrounding stone walls evoke its former grandeur.
From the main enclosure site, you can enjoy a panoramic view of the castle town, including the townscape of Obi and the distant mountains. In spring, cherry blossoms bloom, making it a popular spot for cherry blossom viewing. It’s an ideal place to reflect on history in a tranquil atmosphere.

The exhibits, particularly those concerning the conflicts between the Ito and Shimazu clans, and the displays related to Obi cedar, the industry of the Obi domain, are well worth seeing. It’s a must-see spot for history buffs.
Yoshokan
Yoshokan is the former residence of the Ito clan, built during the Meiji era, and was actually inhabited by descendants of the feudal lord. It was named Yoshokan after the Ito family crest, “Iori Mokko.”

The garden is a pond-centered strolling garden where you can enjoy seasonal flowers. Inside, items related to the Ito family are displayed, allowing you to feel the prestige and high level of culture of the feudal lord’s family.
Komura Jutaro Memorial Museum
In the castle town of Obi, there is a memorial museum for Komura Jutaro, a figure who left his mark on Japanese diplomatic history. Komura Jutaro was born the son of a samurai of the Obi Domain and later served as Foreign Minister, playing a key role in the signing of the Treaty of Portsmouth after the Russo-Japanese War.
The Komura Jutaro Memorial Museum displays materials related to his life and achievements, allowing visitors to learn about Japanese diplomacy during the Meiji era. Following in the footsteps of this great figure from Obi provides a deeper understanding of the cultural background of the castle town.
