FRONTIER CONSULTING Co., Ltd.designed our own workplace, called "OTEMACHI KORTO" in December, 2021. The office, named "KORTO" meaning "courtyard" in Esperanto, is located in "OTEMACHI" which is the center of the Japanese economy and serves as a place to cultivate worker's collaboration.

FRONTIER CONSULTING Co., Ltd., which is a Japan-based workplace consulting firm. We are building forward-thinking workplaces for our clients under the motto "Creating a new work stage."

The Otemachi Building, which we moved in, was built in 1958 by Mitsubishi Estate, a major Japanese real estate developer, as the "largest office building in the Orient." Just recently, as part of its sustainable challenge to become a 100-year-old building, they completed a large-scale renovation, including rooftop greenery and exterior walls, and has been transformed into a facility that attracts a large number of workers. Our workplace is located on the first floor of the building and blends in with the Tokyo city.

Our office "OTEMACHI KORTO" was built based on the concept of a "Purpose-driven Workplace" where society, companies, and workers can implement sustainable work and purpose. As workers' desire for self-realization grows, we can create the following eight work environments through face-to-face and new ways of communication so that companies and workers can realize their own purpose.

1. Share a company's personality and generate empathy
2. Design individual purposes
3. Match between a company and individual purposes
4. Learn what is necessary to realize their own purposes
5. Able to gain autonomy
6. Support community activities
7. Collaborate with stakeholders
8. Feel a sense of self-transcendence that cannot be achieved by an individual

From a spatial design perspective, we used the planning diagram called the Hakugin ratio (Yamato ratio) model, which has been used in Japanese architecture since ancient times to minimize material loss, and distributed rooms and spaces of various sizes.

By using this model, which is believed to have been used in the planning of the Otemachi Building, we carry on the design concept at the time of the building's construction and express the universal beauty of Japanese architecture in the modern design.

In addition, although the dispersed arrangement of rooms and spaces usually leads to a loss of spatial efficiency and unity, the same-ratio planning preserves them, enabling a sequential space configuration with both flow lines and visibility from the outdoors.
