Shiodome Sumitomo Building, Modern skyscraper in Higashi-Shinbashi, Japan.

The Shiodome Sumitomo Building is a 2004 skyscraper in Shiodome with a dark grey facade of closely spaced vertical mullions framing bands of glass. Its lower section projects as a wider base with green-tinted glass and a sloped glass canopy over the entrance. Inside, a tall atrium rises between a dark grey wall with thin horizontal arms and a pale grey stone wall with recessed vertical strips, with escalators descending to a polished dark floor.

Completed in July 2004, the tower was built by Sumitomo Realty & Development with Sumitomo Life Insurance on plot D-North 2 of the Shiodome redevelopment area. The project cost 72 billion yen and combined offices with a hotel. It replaced the former Shiodome freight yard, whose land was released for redevelopment.

The lower ten floors hold the Hotel Villa Fontaine Grand Tokyo Shiodome, run by Sumitomo Fudosan Villa Fontaine, with 497 rooms and a gym. Offices occupy the upper floors, and the ground floor was built as a large atrium reception space, the biggest in Shiodome. Tenants have included JSR's head office, Crédit Agricole and SEGA Sammy Holdings.

Shiodome Station on the Toei Oedo Line and the Yurikamome is directly connected to the building; Shimbashi Station, served by the Toei Asakusa Line, Tokyo Metro Ginza Line and JR lines, is a seven-minute walk away. The hotel occupies floors 1 to 10, while the office floors above are reached through the first-floor atrium. The escalators in that atrium lead down from the entrance level.

The tower stands on plot D-North 2 of the Shiodome redevelopment, built by Sumitomo Realty & Development with Sumitomo Life; it was finished in July 2004 at a construction cost of 72 billion yen. Its base isolation structure was chosen so that the offices stay usable after an earthquake. The 1st-floor atrium, the largest in Shiodome, serves as a reception space.
