The development concept for ARK Hills has the goal of creating a new business town for the 21st century in an era of increasing intellectual productivity, internationalization and greater use of information technology, in order to meet the new demand for a 24-hour business structure centered on Tokyo, London, and New York. ARK Hills is also adjacent to a cutting-edge commercial, cultural, and residential zone in Tokyo connecting Akasaka, Roppongi, Aoyama, and Azabu, and we created the complex as a place for multipurpose and diverse activities in the heart of the city, fusing business and these regional characteristics. Under the guidance of the government, we studied various ways to make the development multifunctional.
We conducted a series of physical studies and market researches and decided the operators who would actually run the complex and the combination of uses it would have, and as a result created the concept of a multipurpose city complex combining business, life, culture, information, and leisure, and offering large-scale, super-high-rise offices, apartment buildings in the heart of the city, a full-scale city hotel, a 2000-seat concert hall, and a television studio.

The next major theme was the creation of a comfortable, relaxing environment while realizing the high level of functionality expected of a central city area. There was a need to maintain the unique environment of each facility while also building an environment that was encompassing enough to enable the buildings to coexist with each other. For this reason we incorporated natural environments to a large degree, including undulating landscaping and greenery and water.

This is also an era of technological innovation. We incorporated as many cutting-edge technologies as possible to create a comfortable environment. We conducted numerous studies of information technologies, which have developed particularly quickly, and in order to meet the needs of an age of pervasive information technology we decided to equip the complex with information structures, and to create a so-called intelligent city featuring intelligent buildings.

The fundamental concept of ARK Hills is the creation of "a total environment city," namely a business city that meet the needs of the current era of internationalization and greater use of information technology, a 24 hour multipurpose city complex, a city with a comfortable environment, and an intelligent city.
