Oka, the residence of the Yanagawa Lord Tachibana family, is a National Designated Scenic Spot located in Yanagawa City, Fukuoka Prefecture. It preserves a history spanning approximately 400 years, continuing the legacy from the era of the first lord, Tachibana Muneshige. The estate covers an expansive area of about 7,000 tsubo (approx. 24,750 m²), all of which holds significant value as a cultural asset. Today, the site is managed by the descendants of the Tachibana family, serving as a venue for luxury accommodations, banquets, weddings, and high-end dining (ryotei). It is a rare space in Japan where guests can feel the passage of time through seasonal scenery and the lifestyle of the former feudal lords.
The history of Oka began in the Edo period as the residence of the Yanagawa Lord Tachibana. The establishment of the site in its current location was greatly influenced by the fifth lord, Tachibana Sadahisa, who moved the residences of his concubines and children closer to Yanakawa Castle. The name 'Oka' (meaning 'Flower Garden') originated from the way the area was once called 'Oka-batake' due to the seasonal flowers blooming around the estate. Through the Meiji era, the family rose to the rank of Count, and despite the turbulence of the pre- and post-war periods, the traditions and culture have been meticulously preserved by the descendants of the Tachibana lineage. It is not merely a historical building, but a 'living history' that continues to weave the local culture today.

Oka features several significant structures and gardens that captivate visitors. First is 'Soteien,' a beautiful Japanese garden designed by the 14th head of the family, Tachibana Kanji. The garden features a central pond with various islands and is surrounded by majestic black pines, symbolizing the harmony between nature and architecture. The 'Grand Hall' (Dai-komi), boasting an area of approximately 100 tatami mats, offers a panoramic view of Soteien, providing a sense of openness and high prestige. Additionally, the 'Western-style Building' (Seiyokan) is a must-see. This white-walled structure, used to welcome important guests during the Meiji era, showcases the advanced lifestyle of the time, including a history of using private power generation before electricity was widespread.
Oka reveals a different face with every season. In spring, seasonal flowers bloom in abundance; in summer, the landscape is lush and green; and in autumn, vibrant foliage colors the garden. The nighttime view, especially watching the moon reflect on the pond of Sotaen, offers a particularly profound atmosphere. The seasonal changes provide guests staying overnight or attending banquets with a deeper sense of immersion. In winter, you may even observe wild ducks gathering in the pond, offering a glimpse into the natural cycle. Because the light and tranquility of the garden change depending on the time of day, please choose your visit time based on your purpose (sightseeing, dining, or accommodation).

Beyond simple sightseeing, Oka offers multifaceted experiences. Guests can enjoy accommodation plans that allow them to stay in the same historic spaces once occupied by lords and counts. The venue also hosts traditional Japanese weddings and dining experiences, including the famous Yanagawa specialty, 'Unagi no Seiromushi' (steamed eel). Combining a visit to Oka with a 'River Cruise' through the canals of Yanagawa creates a perfect itinerary to understand the region's history. Occasionally, the site hosts events that blend tradition with modern design, such as exhibitions of Nordic design, creating a unique intersection of old and new.
The Yanagawa area, where Oka is located, is a famous tourist destination known for its traditional river cruises and 'Seiromushi' eel culture. A common sightseeing route involves enjoying the historic architecture and gardens of Oka before taking a boat tour through the local canals. For those wishing to dive deeper into the Tachibana family's history, a visit to the nearby 'Tachibana Clan Historical Museum' is highly recommended. The surrounding area is dotted with charming old streets and local eateries, making it an ideal destination for a trip themed around history, culture, and gastronomy.

As a site containing National Designated Scenic Spots and cultural properties, appropriate etiquette is required. Please respect the environment when walking through the gardens and entering the historic buildings. Since schedules for accommodation, banquets, and specific tours vary, it is highly recommended to check the official website in advance for details.
