Guida
The Ex-Komoro Honjin is a historic building located along the Kitagoku Kaido in Komoro City, Nagano Prefecture. It originally functioned as both a Honjin and a Tonya. A 'Honjin' was a prestigious lodging facility for daimyo (feudal lords) and high-ranking officials, while the 'Tonya' served as a business hub for managing horses and travel arrangements. The main building and the front gate are designated as National Important Cultural Properties, preserving the architectural style of the late 18th to early 19th century.
This residence originally belonged to the Ueda family, who held both Honjin and Tonya duties in the Komoro post town during the Edo period. In the mid-Meiji era, ownership passed to the Tamura family, and it was eventually donated to the city of Komoro in 1993. As a vital hub on the Kitagoku Kaido, it hosted many traveling officials and lords. Currently, the building is undergoing extensive preservation and repair work to ensure its historical structure is maintained for future generations.
A striking feature is the 'So-nikai' (full two-story) structure facing the road. The second floor extends forward by approximately 75 cm (2.5 shaku) via thick structural beams, adorned with continuous lattice windows. This design is quite rare among historical Japanese architecture. The first floor features a wide veranda (nure-en) facing the street and a traditional tatami corridor. The front gate follows the 'Yakuimon' style, a design that clearly signals the high social status and prestige of the Honjin.
As the building is currently undergoing preservation and repair work (scheduled for completion in 2027), access to the interior is restricted. Visitors can primarily observe the exterior architecture and the historical atmosphere of the surrounding street. While the scenery is beautiful in any season, we recommend visiting during bright, sunny days to best appreciate the textures of the historical wooden structures and the surrounding landscape.
Due to the ongoing restoration, entry into the interior is currently prohibited. However, you can still learn about the mechanics of an Edo-period post town and traditional Japanese carpentry by observing the exterior and the surrounding streetscape. The area features related facilities, such as the 'KOMORO HONJIN OMOYA' dining establishment and other relocated historical structures, allowing for a culturally rich stroll.
The area surrounding the Ex-Komoro Honjin is steeped in the history of the Kitagoku Kaido. You will find various buildings that maintain a traditional atmosphere, including parks where parts of the original main house have been relocated. The site is within walking distance of Komoro Station, making it easy to combine this visit with other local sightseeing spots to gain a deeper understanding of Japan's post-town history.
Please wear comfortable walking shoes for your stroll. As the site is under renovation, it is strictly prohibited to enter any construction zones or restricted areas. While some nearby facilities may accept credit cards, it is always wise to carry cash for local amenities. English signage is limited, so we recommend checking maps or information in advance. Please respect the preservation work by staying within the designated observation areas.
