Muromachi Chibagin-Mitsui building, Modern skyscraper in Tokyo, Japan.

The Muromachi Chibagin-Mitsui building is a skyscraper in central Tokyo with a glass and steel facade. The structure houses office spaces across multiple floors serving different companies and organizations.

The building was constructed in Tokyo's historic business district, which has served as a commercial center since the early 20th century. Its construction reflects the ongoing modernization of this financial area.

The lower floors form the COREDO Muromachi 3 shopping complex, whose main entrance faces the Nihonbashi Mitsukoshi department store across Chuo-dori. The basement connects directly to the Mitsukoshi-mae subway concourse and to the Edo-zakura-dori underground walkway linking COREDO Muromachi 1, 2 and 3. On the third floor, the Hashirakutei/Io-an hall hosts events, and 36 shops and restaurants operate, some facing the Nakamise side street.

The building faces Chuo-dori and Edo-zakura-dori and is directly connected to Mitsukoshimae Station on the Ginza and Hanzomon lines and to Shin-Nihombashi Station on the JR Sobu Rapid Line. The basement concourse of Mitsukoshimae can be reached directly from the B1 entrance. The underground Edo-zakura-dori walkway linking COREDO Muromachi 1, 2 and 3 also serves as an event space and, in a disaster, as a temporary shelter for stranded commuters.

The building was designed with strict earthquake safety standards and features specialized engineering solutions. These features are representative of modern construction techniques in a seismic zone.
