uction industry exemplifies how digital transformation can enrich longstanding craftsmanship rather than displace it. This harmonious fusion is epitomised by three leading construction firms: Shimizu Corporation, Takenaka Corporation, and Daiwa House, each pioneering digital solutions that respect and extend Japan’s heritage of meticulous building.
At Shimizu Corporation, digital innovation is driving a cultural shift toward efficiency and integration at construction sites. Jun Okoshi, Section Chief of BIM Engineering–Digital Construction, highlights the company’s ambition to halve routine tasks through automation and better workflows. Shimizu’s approach combines robotics with advanced digital management tools. For example, their ‘Shimz Smart Site’ concept integrates technologies like SmartStation devices, which provide 360-degree site monitoring, Wi-Fi, remote equipment control, and real-time communication and documentation access. This system dramatically improves on-site coordination and helps reduce delays and errors.
Shimizu has further extended its digital frontier through the development of a metaverse inspection system. By merging 3D scan models with BIM data, inspectors can perform virtual walkthroughs of construction sites, accessing views from multiple perspectives, including a bird’s eye vantage point. Their xR Checker tool automatically compares BIM data to point cloud scans, identifying discrepancies to streamline inspections while reducing physical site visits. Alongside these innovations, Shimizu’s deployment of autonomous construction robots, such as Robo-Welder, Robo-Carrier, and Robo-Buddy, continues the firm’s commitment to alleviating labour shortages and improving productivity through technology seamlessly integrated with human workers.
Takenaka Corporation shares a vision of construction digitalisation focused on data integration and workflow connectivity. Hideaki Takimoto, BIM Group Leader, emphasises the importance of unifying data through platforms like Autodesk Construction Cloud and combining them with business intelligence tools such as Power BI. This creates a single source of truth where schedules, requests for information, issue tracking, and model coordination coexist transparently, enabling swift, informed decision-making from site workers to executives. Takenaka also champions the use of AI to support construction teams by capturing lessons learned and transforming experiential knowledge into digital resources that guide future projects, reflecting a commitment to continuous improvement rooted in practical insights.
Daiwa House, Japan’s largest homebuilder, faces the unique challenge of applying digital innovations at scale. Team Leader Kohtaro Kawakatsu notes that while BIM is fully adopted in design, they are extending its reach through construction and handover phases to create comprehensive digital twins. This integration has already resulted in a 70% reduction in redundant data exchanges between office and field personnel, speeding up workflows and enhancing accuracy. Daiwa views BIM as a “common language” connecting design, procurement, and construction that fosters transparency, accountability, and collaboration. Their focus in the next phase is to embed these digital practices into standard operations company-wide, reflecting a strategic commitment to cultural transformation alongside technological progress.
Together, these firms embody a distinctive Japanese philosophy in architecture, engineering, and construction: technological innovation is not pursued for its own sake but as a means to enhance human craft, wellbeing, and legacy. The aim is to reduce unnecessary burdens on workers, enable creative thinking, and ensure buildings endure for generations. As Daiwa House’s Kawakatsu reflected, the construction industry is inspiring yet constrained by pressure; digitalisation must create a culture of empowerment and growth, not merely efficiency.
Japan’s leading construction companies present a model for the global built environment sector—one that balances cutting-edge technology such as robotics, digital twins, AI, and integrated data platforms with time-honoured values of precision, durability, and respect for craftsmanship. The underlying message is clear: the success of innovation should be measured not only by budget and schedule adherence but by the lasting quality and human value embedded in the structures created. This integration of tradition and technology offers a profound lesson for the worldwide AEC (architecture, engineering, and construction) community—building today for futures defined by resilience, wisdom, and cultural continuity.
