Two subway stops from Umeda, this museum contains a life-sized reproduction of an 1830s Osaka neighbourhood with shophouses, drug stores, an old-style 蝉别苍迟艒 (public bath) and atmospheric lighting that transitions from day to night. You can try out traditional toys and even rent a kimono for photo ops (楼500). Enter the building directly from the subway and take the elevator up to the 8th floor.
From here you can walk south down Japan's longest shopping arcade Tenjinbashi-suji.
