Guide
Kumonoji Koji is a designated National Important Preservation District for Traditional Buildings located in Kunimi Town, Unzen City, Nagasaki Prefecture. This area was once developed as the Kumonoji territory under the Saga Nabeshima Clan, and as a result, the structural characteristics of samurai residences and traditional architectural styles remain vividly preserved. The scenery is defined by bamboo hedges, stone walls, and the gentle sound of water flowing through the streets via local waterways, offering a nostalgic glimpse into the life of the samurai class.
Historically, the area was under the control of the Kumonoji clan before transitioning to the rule of the Nabeshima clan of the Saga Domain. In 1608, the land was granted to Nobufusa Nabeshima, a high-ranking retainer, by the first lord of the Saga Domain, Katsishige Nabeshima. The foundation of the current samurai-style streetscape was established during the era of the 4th head of the family, Takanari Nabeshima, in the Genroku period. In 2005, the area was officially designated as a National Important Preservation District for Traditional Buildings, and in 2006, it received the 'Beautiful Townscape Award,' highlighting its immense value in terms of landscape preservation.
The most iconic landmark in this area is the Kunimi Kumonoji Koji Historical and Cultural Park: The Nabeshima Residence. This estate is famous for its impressive features, including the Nagayamon (gatehouse) with its heavy stone walls and the main building featuring a distinctive Karahafu-style (undulating) gable. Of particular interest are the retirement quarters built in 1860 and the elegant Japanese-style study rooms from the Meiji and Taisho eras, which showcase the lifestyle of the former lords. Visitors can also enjoy the Karesansui (dry landscape) garden, which harmonizes perfectly with the surrounding natural environment.
As this is an outdoor preservation district, there are no specific opening hours for the general streets. However, the scenery changes beautifully with the seasons. In winter, you can see the delicate beauty of Hikanzakura (winter-blooming cherry blossoms), while in spring, seasonal flowers like azaleas add vibrant color to the gardens. On clear days, the landscape is so elevated that you may catch a glimpse of Mount Unzen-Kusaki or the distant mountains of Kumamoto Prefecture.
The primary way to enjoy Kumonoji Koji is through a leisurely stroll through the historic streets. You can observe the intricate structures of traditional buildings and the way the waterways integrate with the residential life. For those seeking deeper knowledge, local facilities such as the historical and folklore museums provide valuable insights into the regional history and culture.
The district is conveniently located just a 5-minute walk from Kumonoji Station on the Shimabara Railway. The area is surrounded by various other tourist attractions within Unzen City, and the entire district—including the stone walls, hedges, and buildings—is meticulously preserved as a unified historical landscape.
When walking through the district, please respect the local etiquette to help preserve the historical atmosphere and the integrity of the stone walls and waterways. Please note that while the streets are free to walk, specific facilities like the Nabeshima Residence may require an admission fee. It is recommended to wear comfortable walking shoes for exploring the uneven paths.
