Shibuya Infoss Tower, Commercial skyscraper in Shibuya, Tokyo, Japan

The Shibuya Infoss Tower is a commercial office building in Shibuya with a sleek glass and steel facade that rises prominently above the surrounding district. Inside, the structure features open floor plans designed for business operations, with public-facing retail and service spaces occupying the lower levels.

Developed and owned by Sumitomo Realty & Development, the tower was completed in March 1998. It was the first high-rise to be finished around Shibuya Station in about 23 years, since the Toho Mutual Life head office building. Its office floors housed IT firms such as InterQ, later part of GMO Internet Group, and the building contributed to the area later called Bit Valley around 1999.

The name Infoss Tower combines "info" and "S" for Sakuragaoka, the district where it stands. Its office floors housed InterQ, later part of GMO Internet Group, and other IT firms, making the building part of the area credited with coining the term "Bit Valley" around 1999. Sculptor Kiyoshi Awazu's work "Tennyo" stands at the road entrance near the site's northwest corner.

The tower stands in Sakuragaoka-chō, a short uphill walk from Shibuya Station's west side; the irregular plot leaves a natural park on the north and west and a pocket park on the south, with sightlines running north to south. The entrance floor and the basement fitness club are reached from the street corner marked by Atsuji Kiyoshi's sculpture "Tennyo".

The tower's 21st and 20th floors are residential, operated as the rental apartment Shibuya Infoss Tower Heights, so offices and homes share one building. At the northwest corner of the site, where the road leading to the entrance begins, stands Kiyoshi Awazu's sculpture "Tennyo" (Celestial Maiden). Completed in March 1998, it was the first high-rise finished around Shibuya Station in about 23 years, since the Toho Mutual Life head office building.
