Tora Asa will forge a “city within the city” revitalizing Tokyo's city center

Tokyo, Japan

Conceived as a modern urban village, Toranomon-Azabudai weaves together a dynamic and innovative mixed-use development. Tora Asa will rise from the development as a new visual landmark in Tokyo. Topped by four curved glass petals, the tower is expected to become the Japan’s tallest building upon completion, standing just shy of the nearby landmark Tokyo Tower.

At over 300 meters in height, Tora Asa will become Japan's tallest building upon completion, just shy of the nearby Tokyo Tower.

The Toranomon-Azabudai site, located next to other major recent developments, will connect into a new international urban center with an economic and cultural focus.

A lifestyle of seamless connection 

As a true mixed-use development, the project’s three towers will include offices, residences, a hotel, an international school, retail shops, restaurants and cultural facilities. The development is three towers in total. Alongside the taller mixed-use tower there will be two residential towers. Aman, the operator of world-class luxury hotels and resorts, has branded one tower as Aman Residences and the other Janu Tokyo, Aman's luxury hotel brand. Janu Tokyo will mark Aman's Japan debut.

"Out of our three projects on the site, the main tower is perhaps the most visual on the skyline. It is the first thing visitors will see upon arrival in Tokyo." – Fred Clarke, FAIA, RIBA, JIA

Giving new life to the neighborhood, Tora Asa will further enrich the area’s international influence and multicultural diversity.

A world of its own 

Welcoming, friendly, and transparent, the architecture will instill a creative urban environment where people connect with nature and one and other. At the base of each tower, a “village green,” designed by Heatherwick Studio, will take root as a central gathering place for residents and visitors, filled with native trees, lush flowers, and waterscapes. Abundant green space throughout the site will offer a window to the natural world amid the daily bustle of an expansive city.

Innovation to promote safety 

The Tora Asa site is envisioned to be a “city where people can flee to” in the event of a natural disaster. The towers are designed to ensure infrastructure stability and incorporate earthquake-resistant technologies by applying data captured from the 2011 Great East Japan Earthquake. The site will also include temporary shelter space and an emergency supply warehouse.
