The Former Konishigata Residence Museum, located in Doshomachi, a pharmaceutical wholesale district, is a Japanese-style building that culminates modern Osaka's townhouses. Konishi Gisuke Shoten (now Konishi Co., Ltd.), which was founded in 1870 as a drug dealer, built the house over a three-year period starting in 1900, and completed in 1903. High-quality materials were used for the building, and although it is simple, traces of elaborate design and ingenuity can be seen in each room and tea room. The kitchen has a large hearth that was used to cook meals for around 50 people, including the family and employees. It was renovated as a historical museum in 2020, to mark the 150th anniversary of the company's founding (reservations required).
