Shiodome Building, Commercial skyscraper in Shiodome, Japan

The Shiodome Building is a skyscraper in the Kaigan business district and contributes to Tokyo's skyline with its glass and steel structure. The tower holds office spaces, retail areas, and connects directly to nearby subway stations through underground passages.

Developed by Tokyu Real Estate and Mitsubishi Estate using a non-recourse loan and equity financing from Tokyu Fudosan, Mitsubishi Estate, Mitsui & Co. and Heiwa Real Estate, the building was the last large project of the Shiodome Sio-Site redevelopment. It stands near Hamamatsucho Station, at the southern gateway of the district, away from Shiodome Station at its centre. Japan Real Estate Investment Corporation acquired a 10% co-ownership stake in 2008 and has held 55% since 2017.

The lower two floors hold a food and drink zone called Hamasite Gourmet, themed as a new dining spot near Hamamatsucho. The site is the southern gateway of the Shiodome Sio-Site redevelopment, next to the Shiodome Shibarikyu Building and the Bunka Hoso headquarters. A bridge at second-floor level receives the pedestrian deck from the neighbouring building.

The building connects easily to public transit through underground passages, which helps avoid long walks in bad weather. Ground-level entrances to shops and restaurants are accessible from outside and straightforward to navigate.

The building is often confused with Tokyo Shiodome Building in Higashi-Shinbashi, but it stands far to the south, by Hamamatsucho Station, as the southern gateway of the Shiodome Sio-Site redevelopment. It was the last large project of that district. Its second-floor shared entrance is reached by a bridge from the pedestrian deck of the neighbouring Shiodome Shibarikyu Building.
