The Former Asa Mori Family Hagi Residence Nagaya is the samurai residence of the Asa Mori family, descendants of Motoaki, the fifth son of the legendary daimyo Mori Motonari. The family was granted land in the Asa area near present-day Sanayoshi-nada, Sanyo-Onoda City, following their relocation to Hagi. While the estate once spanned a vast 15,500 square meters, only this long 'Nagaya' (longhouse), built in 1856, remains today. It is recognized as one of the most significant and large-scale samurai residences still standing in Hagi and is designated as a National Important Cultural Property.
The Asa Mori family played a vital role in the history of the Mori clan. This residence dates back to the Ansei era (1856) of the late Edo period, serving as a precious relic that illustrates the social structures and lifestyles of the samurai class. It once stood as a centerpiece of a grand estate that shaped the local history. Today, it is meticulously preserved and managed as a cultural asset to pass down traditional Japanese architectural styles to future generations.

The most striking feature is the massive scale of the building: a long, Irimoya-style (hip-and-gable) structure with a width of 5 meters and a length of 51.5 meters, topped with traditional heavy tiles. The interior is divided into five sections, notably lacking the 'doma' (earthen floor) found in many other buildings. The eastern section features a highly dignified design with tatami-matted corridors, believed to have been used as an office or waiting area for high-ranking officials. Visitors can experience the authentic atmosphere of a high-ranking samurai's living space through its detailed architectural elements.
In the scenic landscape of Hagi, the residence displays different charms throughout the seasons. Visiting during the bright daylight of spring, summer, or autumn is ideal for appreciating the textures of the wood, the tatami mats, and the intricate structural details. Observing how the light changes throughout the day allows you to visualize how the building originally sat within its natural surroundings and historical environment.

Visitors can gain a deep understanding of late Edo-period construction techniques. The space offers a rare opportunity to stand within a high-status residence, characterized by its elegant tatami corridors and grand roof structure. It is a perfect place to touch upon the traditional Japanese way of living and the formal spatial configurations that defined the samurai class.
The area around the residence is rich in history, with nearby sites such as Hagi Castle Ruins, Shizuki Park, the Hagi Ware Museum, and Tenju-in Temple. To explore these sites efficiently, it is recommended to use the common ticket (common pass) which covers multiple locations. Exploring the nearby Hagi-yaki (Hagi pottery) facilities will also provide a multi-faceted understanding of the local culture.
