Introduction to Our Facilities

“Building for the future while preserving and resurrecting history”
A landmark that aims for harmony between people and the urban environment

Nihonbashi Mitsui Tower is a skyscraper that symbolizes urban rejuvenation. The structure was built with the concept of passing on the historical and cultural heritage of the original Mitsui Honkan that was completed in 1929 (and designated an important cultural property in 1998), while being a part of the redevelopment of Nihonbashi. The new structure is a premium office building that harmonizes tradition and the spirit of innovation. At the same time, it provides the district with a sense of openness. It is one of the landmarks of Nihonbashi where people and the urban environment can coexist together.

This is one of the most valuable collections of cultural heritage in Japan which has been handed down to the present times. The Mitsui Honkan building, where the Mitsui Memorial Museum is housed, has been designated as an important cultural property of Japan for its profound Western-style architecture that represents the Japan of the early Showa Era (1926-1989). An entrance to the museum has been established in the atrium of the Nihonbashi Mitsui Tower skyscraper which has been built adjacent.
