Atrium

Found at the first-floor entrance to Nihonbashi Mitsui Tower, the Atrium is a sun-kissed, expansive space that extends all the way up to the fourth floor of the building, with a total height of around 26 meters. With the awe-inspiring Historical Wall acting as a backdrop, the luxurious, marble-lined Atrium is available for use as an event space. The Atrium is an outstanding place to put on small-scale concerts and other events, with its diverse crowd of passers-by including hotel guests, museum patrons, and office workers. Please note that events must first be evaluated and approved by Nihonbashi Muromachi Area Management; Mandarin Oriental, Tokyo; the Mitsui Memorial Museum; and Sembikiya-Sohonten.
