The Nakamura family home is one of the townhouses that has been around since the 1600s, when Tondabayashi Jinanimachi began to flourish. Like the former Sugiyama family home, the only townhouse in Jinanimachi that can be toured, the Nakamura family home was a sake brewery called Sadoya, boasting one of the largest sake breweries in Kawachi Province (near present-day Minamikawachi County) in the mid-Edo period. Records of a large store remain, including Yoshida Shoin's stay of nearly a month at the end of the Edo period, as well as other notable guests. The current house is not from that time, but was built around 1782 and has been designated a cultural property of Osaka Prefecture. It is now a valuable building, built in the architectural style of merchant houses commonly seen in Osaka and Kyoto, but as it is a private residence, the interior is not open to the public.
