A Green Valley in the Heart of Roppongi

Completed in August 2012 in the Roppongi 1-chome district of Minato City, Tokyo, the Ark Hills Sengokuyama Mori Tower rises 48 storeys above ground and four below. At roughly 206.7 metres and a total floor area of approximately 143,426 square metres, it is one of the taller mixed-use towers along the Toranomon–Azabudai corridor. Retail occupies the lower floors, residences fill floors 3 to 24, and offices run from the 25th floor to the 47th. Design was led by Mori Building Co.’s in-house architectural practice.

What sets the tower apart from most Tokyo skyscrapers of its scale is the generous garden that spreads across the base of the site. The hillside terrain of Sengokuyama has been shaped into a landscaped garden with significant changes in level, and visitors arriving from Roppongi-itchome Station walk through that greenery before reaching the building entrance. The garden changes with the seasons, and the experience of approaching through it is closer to entering a park than a high-rise tower.

Ark Hills Expanded: Twenty-Six Years in the Making

The Ark Hills precinct traces its origins to the 1986 completion of the Ark Mori Building, the office centrepiece of Mori Building’s flagship mixed-use development in Akasaka. For more than two decades the precinct — anchored by Suntory Hall and the Ark Mori Building — remained largely as first constructed. The Sengokuyama Mori Tower, delivered under the Toranomon–Roppongi District Urban Redevelopment project, renewed the remaining parcels of ageing low-rise housing and added a residential and green-space layer that had been absent from the original 1986 scheme.

Roppongi-itchome Station connects underground directly to the tower, making it accessible without stepping into the rain. The precinct sits within walking distance of the rapidly evolving Kamiyacho–Toranomon axis and the newer Azabudai Hills complex, placing Ark Hills at a node in a continuous strip of large-scale development reshaping western Minato City.

Summary

The Ark Hills Sengokuyama Mori Tower was completed in August 2012 with 48 floors above ground and a height of approximately 206.7 metres. As the expansion of a precinct that began with the Ark Mori Building in 1986, it adds a residential programme and a landscaped garden to the long-established Ark Hills site. The garden approach from Roppongi-itchome Station — walking uphill through greenery before arriving at a skyscraper entrance — is unlike almost any other journey to a tall building in central Tokyo.
