OKUMURA CORPORATION + MR STUDIO Co.,Ltd.: Winner of World Design Awards 2025. DAISHINKU CORP. is a leading Japanese company engaged in the manufacturing and sales of quartz devices. This project aims to create a smart factory that integrates headquarters and plant functions on a site adjacent to the existing Central Laboratory. The exterior design is inspired by stacked crystal chips. Five layered rectangular volumes of different sizes represent DAISHINKU’s history of technological innovation and its future growth.

Additionally, the stacked volumes are designed to rise gradually, expressing the company’s technological evolution and growth in an upward trajectory, creating an impressive design full of dynamism.

The specific frequency characteristics of a crystal-derived chip are determined by the interplay of its thickness and angle. The architectural design focuses on the thickness of these chips, creating the space by layering volumes of varying thicknesses. This design inspired by the stacked crystal chips not only extends to the exterior but also permeates the interior space, thus visualizing the corporate identity.

The slight misalignments between the stacked layers generate shifting shadows and variations in expression, reminiscent of the subtle deformations of crystal under pressure and temperature changes while maintaining a stable frequency. This interplay creates a space where science and design harmonize.

Each floor is organized around an atrium pierced through the center, with natural light from the skylight spreading across each layer. This not only enhances energy efficiency and openness but also stimulates encounters and communication among workers on different floors.

The interior lighting is designed with a focus on the angles of the chips cut from crystal. The thickness of the processed chips is a key factor in determining the device’s resonance frequency, while the angle is an element that affects the stability of that frequency. The most commonly employed 35.15°AT cut, as well as the 38°CT cut and 52°DT cut, is used to design interior line lighting based on these unique angles. This line lighting creates an innovative lighting environment that embodies DAISHINKU’s identity, as different angles intricately combine within the space.

In addition, changes in color temperature based on the circadian rhythm have been incorporated, enhancing intellectual productivity. These designs are emblematic of DAISHINKU’s dedication to technological innovation, realizing a holistic and symbolic spatial experience that unites.
