Based on the concept of "Nihonbashi, livening up Japan," the commercial zone recreates the bustle of the Edo period and is home to a variety of stores, from long-established stores that are steeped in the history of Nihonbashi to new, innovative stores such as new formats of popular stores. The Nihonbashi Mitsui Hall on the 5th and 6th floors is one of the largest multipurpose halls in the Nihonbashi area.
