What other travelers are saying about Mitsui Main Building
The Mitsui Main Building stands as one of Nihonbashi’s most important architectural landmarks and a defining example of early modern Japanese commercial architecture. Completed in 1929 as the headquarters of the Mitsui conglomerate, the building was designed in a restrained Neo-Classical style, with a granite façade, fluted columns and a clear sense of symmetry that projected stability and confidence during a period of rapid economic growth.
Inside, the building once housed the central banking and administrative functions of the Mitsui group, reflecting the family’s long-standing role in the development of Japanese finance and industry. The interiors were finished with marble, brass and carefully crafted woodwork, and the vault areas — still preserved — testify to the building’s original status as a financial stronghold. Despite its modern Western-influenced design, the proportions and materials were chosen to harmonise with the cultural weight of Nihonbashi, historically Japan’s centre of commerce.
