Kitsuki Castle is a historic fortress located in Kitsuki City, Oita Prefecture. Originally constructed by the Kitsuki clan in the early Muromachi period, the site is characterized by its status as a natural stronghold surrounded by the sea and steep cliffs. Due to its topography, it is also known as "Gayu-jo" (Ox-lying Castle). Today, the castle ruins are maintained as Kitsuki Castle Hill Park. A three-story replica castle tower stands on the site of the former main keep (Honmaru), serving as both a museum and an observation deck where visitors can view historical artifacts and enjoy the surrounding scenery.
The site has a long history, beginning with "Kitsuki Castle" built by reliance on Kitsuki Yorinao in 1394. During the Sengoku (Warring States) period, it was a site of intense conflict between the Otomo and Shimazu clans. In the Edo period, it functioned as the administrative center of the Kitsuki Domain. However, following the 1615 edict to limit the number of castles, the upper fortifications were dismantled, and the administrative functions moved to the lower castle town. Today, the area remains an important historical site, featuring stone monuments and remnants of stone-carving culture that tell the story of the region's heritage.

The greatest draw is the view from the castle tower. From the three-story replica structure, you can enjoy a panoramic view of Kitsuki City and the beautiful Morie Bay. The museum inside the tower displays precious artifacts, such as samurai armor used by the lords and the "Bungo Ume no Tsubo" (Bungo Plum Jar) presented to the Shogunate. Additionally, visitors can see the remains of earthworks and trenches, providing a visual understanding of the original castle's defensive structure. The surrounding paths also feature various stone-carved cultural relics, including the Kunisaki towers.
The castle offers different charms depending on the season. In spring (around March to May), approximately 250 cherry trees bloom along the walking paths, making it a popular spot for hanami (flower viewing). In the evening, the setting sun casts a beautiful glow on the white walls of the castle tower, bathing the entire site in vibrant colors. In autumn, the area hosts events like the "Moon Viewing Festival," where visitors can enjoy traditional tea ceremonies under the light of the full moon and lanterns, offering a deep sense of historical elegance.

As a well-maintained park, Kitsuki Castle Hill Park is perfect for a relaxing stroll through nature while learning about history. Through the museum exhibits, you can learn about the history of Oita and the lifestyle of the local lords. Participating in seasonal festivals is also highly recommended. For example, the "Kitsuki Castle Festival" in May features an "Edo Procession" where participants dress in traditional Edo-period clothing, allowing you to experience the atmosphere of an ancient castle town. In winter, the "Hina Matsuri" festival showcases precious traditional dolls in local merchant houses and samurai residences.
The area at the foot of the castle ruins is known as the "Lord's Palace District," where stone walls and garden remains can still be seen. The "Old Funagata Residence" in the Kiban district is another notable structure still used as a private home today. We recommend a walking tour through the historic streets of the castle town, visiting the sites of former samurai residences and the local shopping streets that preserve traditional craftsmanship.
While the site is a maintained park, the paths can be sloped or unpaved. We highly recommend wearing comfortable walking shoes. Please note the following:
