A building that embodies the renewal of Toranomon

Appearing in 2023, directly connected to Toranomon Hills Station on the Tokyo Metro Hibiya Line, is Toranomon Hills Station Tower. Located in Toranomon, Minato City, this building rises to 49 floors above ground and a height of 266 m, holding a central position in Mori Building’s development of the Toranomon Hills area.

The area around Toranomon has changed greatly in appearance over the past decade or so. It was once often seen as an extension of the government office district adjacent to Kasumigaseki, but through continuous redevelopment by Mori Building, it is now said to be recognized as an international business hub. Station Tower was completed amid that flow, and its structure, integrating station and building, drew attention also from the perspective of connecting urban infrastructure with private development.

The presence of 266 m and its impact on the urban landscape

When you actually walk the site, you realize that the figure of 266 m carries meaning beyond mere specifications. Looking up from the surrounding roads, the vertical lines of the exterior wall, stretching straight toward the sky, dominate your field of view. There are many tall office buildings in the city center, but what is distinctive about this tower is that, because of its location above the station, a certain amount of open space is secured between it and surrounding buildings, so its tower-like silhouette can be made out relatively cleanly.

Planned as an office building, it has a structure that densely concentrates the city’s business functions while enabling access from a wide area through the convenience of being directly connected to the station. Such vertical concentration could be called one answer to the challenge that modern redevelopment commonly pursues: using limited land efficiently within the city.

For the Toranomon Hills area as a whole, multiple buildings have been completed in stages, and the completion of Station Tower marks one milestone in that development. The construction of streets and public spaces mindful of continuity as an area is also advancing, so a perspective is required that evaluates not only the presence of individual buildings but the composition of the whole district.

Summary

Toranomon Hills Station Tower, an office building with specifications of completion in 2023, 49 floors above ground and a height of 266 m, is a building that shows the culmination of Mori Building’s Toranomon redevelopment. Its location directly connected to the station, its role within the whole district, and the change in urban landscape created by its 266 m height — reading these together reveals that the building exists within an urban context that goes beyond a single piece of architecture. For those who follow high-rise architecture, it is well worth a visit as a place where you can feel the transformation of the town of Toranomon firsthand.
