Located in Namba 5-chome, Chuo-ku, Osaka, Namba Nan Nan is known as the pioneer of underground shopping malls in Osaka. In conjunction with the opening of the adjacent Namba Marui, the mall has undergone its second complete renovation since 1974, changing its concept from an "underground mall" to a "station-close" mall that people will want to stop by every day, and all 69 tenant stores have been relocated into three zones: "Yosoi" for fashion and miscellaneous goods, "Yorozu" for cosmetics and medicines, and "Shoku" for food and drink. In the center, devices that release seasonal scents have been installed on the ceiling and elsewhere, transforming the mall into a more comfortable underground mall.
