This rare historical building is a designated Important Cultural Property of Japan, one of only two remaining tonya-ba buildings in the entire country.
The Former Komoro Honjin is the former Ueda family residence, which served as both a honjin and a tonya-ba in Komoro-juku post town along the Hokkoku Kaido. With only two such tonya-ba structures remaining nationwide, its main building and gate were designated as Important Cultural Properties of Japan in 1973 due to their rarity and historical significance. Estimated to have been built in the late 18th to early 19th centuries, the main building faces the Hokkoku Kaido, boasting a large gable roof and a second floor with lattice windows extending outward on brackets. The gate, a Yakui-mon style gate, served as the entrance to the honjin compound. Both structures vividly retain the atmosphere of the time. The Former Komoro Honjin is a crucial historical site that speaks to the history and culture of the Hokkoku Kaido and is an indispensable part of Komoro's history. When visiting Komoro, be sure to stop by and experience a glimpse into the past.
