seven overlapping gabled roofs spread over haruna innovation center in japan

Haruna Innovation Center’s roof mimics a mountain ridge

The Haruna Innovation Center designed by Naomi Sato Architects serves as the central hub for product planning and development for Haruna Beverage, located at the foot of Mt. Haruna in Gunma Prefecture. The design concept draws inspiration from the surrounding landscape, incorporating repeated gable roofs that echo the natural rhythm of the forest and mountain ridge.

The facility is structured around three primary functional areas to facilitate communication and innovation: the Office Area, the Innovation Area, and the Gallery Area. The office zone shapes a flexible workspace designed to encourage collaboration and co-creation through an open, free-address layout. The innovation area features a laboratory where researchers engage in sensory-driven experimentation. The gallery offers visitors a space to experience the company’s products and gain insight into its development processes.

Naomi Sato Architects’s design balances openness and privacy

The architectural team at Naomi Sato Architects prioritizes a bright and natural working environment. The use of warm materials, such as wood, combined with controlled daylighting through roof gaps, creates a well-lit and green-infused atmosphere throughout the building. The zigzag layout defines distinct spatial experiences, balancing dynamic and quiet areas in the Gallery, while fostering a mix of open and private workspaces in the Office Area. This arrangement contributes to an open, balanced ambiance.

The structure employs a fireproof wooden framework, selected for its fire resistance, seismic stability, and cost efficiency. This exposed structural system enhances both safety and warmth in the interior. Sustainability measures include high-insulation roofing and walls, floor-supply air conditioning, and the strategic use of natural light, reducing energy consumption while maintaining comfort.
