Interior design by Riccardo Daniel with Arper mirrors this harmony. Light surfaces are paired with furnishings in greens and warm autumnal tones, helping define the mood and purpose of each space. With creative director Ichiro Iwasaki bridging Sigma and Arper, the interiors balance “concentration” and “relaxation” to support the precision-driven work of Sigma’s teams.
Arper’s “open desk” concept—endorsed by CEO Yamaki Kazuto—introduces a more fluid and interactive way of working, marking a progressive shift for Sigma and for Japanese corporate culture overall.

Sigma’s new headquarters in Kawasaki, designed by Kajima Design Studio, embodies a dynamic dialogue between workspace and nature. Set against a hillside near Shinkōji Park, the complex is composed of two bright buildings—housing offices, laboratories, darkrooms, and exhibition areas—linked by a dark monolith that presents Sigma’s technological and design history in a museum-like layout.
Greenwise’s landscape design strengthens the building’s bond with the seasons: cherry blossoms in spring, golden oaks in autumn, and green corridors and patios that weave nature throughout the site. The mirror-brushed aluminum façade further blends the architecture into its surroundings.
Sustainability guided the project through the use of prefabricated structures, a rooftop garden made from reused excavation soil, and a photovoltaic system that powers the entire building and its EV charging stations.
