The former Nishio family home, the headman of the Sento Imperial Estate, who provided offerings of rice and vegetables to the Imperial Family and the Niiname-sai festival at Ise Grand Shrine from the estate of the retired emperor who abdicated, sits on a site of approximately 4,300 square meters and includes a sukiya-style front gate (formerly known as the former Nagayamon gate), main house, detached building, tea room, storehouse, and garden. While the exterior is purely Japanese architecture, the interior features a Western-style wing, a billiards room, and a Western-style room with Art Nouveau stained glass, creating a luxurious structure that gives a glimpse of the splendor of the past. At one point, the house was paid in kind to the Osaka Regional Taxation Bureau as inheritance tax, and there was talk of demolition, but due to a campaign by local residents to preserve it, Suita City was entrusted with its management, and it is now open to the public as the Suita Cultural Creation Exchange Center.
