Guide
The Koma-ya Residence is a historic building located in Hidaka City, Saitama, dating back to the early Edo period. It served as the residence for the Koma family, who held the position of Shinto priests at the nearby Koma Shrine. This structure is particularly significant because it preserves an extremely ancient architectural style among the traditional folk houses of Eastern Japan. On June 22, 1976, it was officially designated as a National Important Cultural Property. It offers a rare opportunity to observe the structural design of traditional Japanese dwellings and understand the historical context of the region.
The residence is estimated to have been constructed in the early 17th century (the first half of the Edo period). It has been carefully preserved through generations as the home of the Koma family, the lineage of priests for Koma Shrine. The architectural style deeply reflects the traditional lifestyle and structural forms of that era. Notably, in 2017, the residence gained further historical significance when it was inspected by the then Emperor Akihito and Empress Michiko during their visit to Koma Shrine.
The building features an 'Irimoya-zukuri' (hip-and-gable) roof structure covered with traditional thatch (kayabuki). The scale of the building is impressive, with a length (ketayuki) of approximately 14.3 meters (7.5 ken) and a width (hariyuki) of approximately 9.5 meters (5 ken). The interior follows the 'Ko-yonkemadori' layout, consisting of a rear parlor, a large formal reception room (omote-zashiki) spanning 21 tatami mats, and various utility areas including a kitchen and earthen floors (doma). These elements allow visitors to study the sophisticated architectural techniques and daily lifestyles of the past.
Located within the grounds of Koma Shrine, the residence is surrounded by a beautiful natural environment. Visitors can enjoy the changing textures of the thatched roof and the surrounding vegetation through the seasons. Please check the latest local information regarding specific opening hours or seasonal changes.
This site offers a visual masterclass in traditional Japanese folk house construction. The Irimoya-zukuri style and the expansive room configurations are vital pieces of Japanese architectural history. Visitors can enjoy a quiet, contemplative tour focused on observing the intricate details of the historical structure.
The Koma-ya Residence is situated directly behind Koma Shrine, making it easy to combine a visit to the shrine with a tour of the residence. The area also features other historical sites, such as the Koma Village Stone Age Dwellings, allowing for a rich historical walking route.
