We were in charge of the planning, concept design, and construction of the entrance renovation for Head Office (main building) of Oji Holdings Corporation. The concept was "Forest Field." To express the company's commitment to working in harmony with forest resources in the entrance, we aimed to create a realistic space where one can feel the healing power of a forest even while in an office building in the heart of the city, by effectively arranging native trees and wooden furnishings. The wooden furnishings were made from coniferous trees such as fir and larch, and hardwoods such as oak and birch, harvested from the company's own forests. We made extensive use of solid wood to create a beautiful and warm space that is unique to wood.
