Isoya-tei, located in Kitsuki City, Oita Prefecture, is a precious architectural relic that preserves the history of a samurai residence from the Edo period. Situated in an area once known as the 'Kita-dai Karo' district, the residence is characterized by a calm and dignified presence that evokes the lifestyle of the samurai during the feudal era. More than just a display of a historic building, the site serves as a cultural hub where visitors can simultaneously enjoy the beauty of traditional Japanese ink wash paintings at the 'Kitsuki City Katsumi Kurihara Museum' and the architectural elegance of the estate.
The history of this residence is profound, dating back to the Edo period. Historical records indicate that a person named Anzai Genbei resided here during the Horeki era (1751–1763). Following the Kansei Great Fire of 1800, the site was incorporated into part of the 'Rakujutei' official residence. After the Rakujutei was abolished in 1824, the site resumed its role as a samurai residence. Documents from the early Meiji era and those donated by the Kato family reveal that this was the residence of Kato Yoemon (a high-ranking official with a 200-koku stipend). While the architecture retains the style of the early 19th century (Bunsei and Tenpo eras), recent surveys have discovered roof tiles and plaques dated to 1864 (Bunkyu 4 and Genji 1), providing significant historical evidence of the late Edo period.

One of the greatest charms of Isoya-tei is its meticulously designed landscape, which allows views of the seasonal Japanese garden from every room. The quintessential Japanese scenery—composed of traditional tiled roofs, white plaster walls, wooden pillars, and wide verandas (engawa)—offers visitors a sense of profound tranquility. Additionally, at the onsite Katsumi Kurihara Museum, you can appreciate precious ink wash paintings donated by the late artist Katsumi Kurihara from Chiba Prefecture, allowing for a deep encounter with Japanese aesthetics through both architecture and art.
The Japanese garden changes its expression with every season, offering a unique charm whenever you visit. You can enjoy the cherry blossoms and plum blossoms in spring, the lush greenery of summer, the vibrant autumn foliage, and the quiet, serene landscapes of winter. While it is common to relax on the veranda (engawa) to watch the garden in the daylight, the late afternoon is particularly recommended for photography, as the shifting sunlight creates beautiful shadows and highlights across the garden.

Visitors can experience the traditional Japanese way of living firsthand. Sitting on the engawa while gazing at the garden is a special way to forget the bustle of modern life. Furthermore, exploring the ink wash paintings at the museum provides a deeper understanding of Japanese pictorial culture. Learning about the structure of a samurai residence and the lifestyle of that era will enrich your understanding of Japanese history.
Isoya-tei is nestled within the historic streets of Kitsuki. Other samurai residences, such as the Ohara-tei, are scattered nearby, making it easy to enjoy a stroll through the historic district on foot. There are also hot spring facilities in the vicinity, allowing you to plan a relaxing soak after your historical exploration.
When viewing the gardens and architecture, please follow etiquette to protect these historic structures. As the grounds include gravel, stone paths, and steps, comfortable walking shoes are highly recommended. To protect the museum exhibits, please follow local instructions regarding photography restrictions.
