About Miroku Nissho In Blue 工業廠房

Miroku Nissho In Blue係一座位於日本高知縣南國市嘅工業廠房。設計將槍械工藝嘅精密度轉化為建築形態。建築體量源自公司標誌上三個互相扣連嘅圓環,為龐大嘅建築體帶嚟節奏感同連貫性。外牆採用特製藍色塗層嘅波紋鋼板,靈感嚟自精工細作嘅金屬同仁淀川嘅深藍色。鋼桁架結構造出44米無柱跨度,令生產樓層保持開闊,設備佈局同物流安排都可以靈活調整。

Unique Properties
This industrial facility transforms the philosophy of precision firearm craftsmanship into architecture. Derived from the three interlinked rings of Miroku’s logo, the form expresses rhythm, continuity, and tension within a vast volume. Finished in Miroku Blue, inspired by finely crafted metal and the deep blue of the Niyodo River, the building visualizes corporate identity through material clarity, structural precision, and monumental simplicity.

Production Technology
Steel structure with 44 meter column free truss span enables uninterrupted production lines. Exterior is finished with K Wall ribbed steel panels in custom Miroku Blue coating. Floor slab thickness ranges from 450 to 600 mm for future production flexibility. Structural precision reflects the manufacturing philosophy.
Design Challenge
The primary challenge was reconciling symbolic architectural expression with strict industrial functionality. Internally, the project required translating over a century of craftsmanship philosophy into spatial form without reducing it to mere representation. Externally, long span structural limitations, production efficiency demands, cost constraints and regulatory requirements shaped the design. The solution was achieved through structural optimization of a 44 meter column free span and disciplined facade articulation, balancing monumentality with operational precision.
Research
Type of Research: Architectural semiotics and industrial spatial research.
Research Objectives: To transform symbolic corporate elements into structural and spatial systems.
Methodology: Semiotic analysis of logo geometry, structural optimization of 44 meter span trusses, facade performance studies.
Data Collection: Production flow analysis, environmental performance simulation.
Participants: Multidisciplinary team of architects and engineers.
Results: A column free industrial monument integrating ZEB Ready environmental strategy.
Insights and Impacts: Repositions factory architecture from utilitarian infrastructure to identity driven cultural asset influencing corporate branding and regional perception.
Inspiration
Since its founding in 1893, Miroku has pursued firearms not as mere tools but as works of art defined by precision and beauty. This philosophy inspired the architectural concept. The corporate blue, rooted in the landscape of Kochi and the clarity of the Niyodo River, became the central motif. The building extends craftsmanship into architectural scale, redefining industrial production as artistic expression.
Project Duration
The project started in June 2023 in Kochi and was completed in January 2025 in Nankoku, Japan. The facility consolidates production and administrative functions within a unified architectural volume reflecting corporate heritage and regional identity.
Operation Flow
Production, logistics and administration are organized along a clear spatial axis. Column free spans enable flexible equipment layout and operational efficiency. Visual continuity between zones enhances spatial awareness, transforming industrial workflow into a coherent architectural experience.
