[Obayashi] New Business Domains — Smart Buildings, Robots, Urban DCs

Beyond its five established business segments, Obayashi runs a formal process for exploring new business domains — the start of what the company hopes will become new sources of consistent growth as the core construction business matures. This page of the Investors’ Guide 2026 covers how focus areas are chosen, how ideas move from concept to profit, and the three companies the group has already spun off.

Mission and selection criteria

Obayashi describes its most important mission for this business as addressing social issues such as carbon neutrality and well-being, and contributing to a sustainable society — creating an organization that enjoys consistent growth by boldly exploring initiatives beyond its core business areas. Candidate focus areas are screened against two criteria: whether the opportunity lets the Obayashi Group demonstrate the power of its vision, creation, and people, and whether the market itself offers sufficient scale, business opportunities, and future growth potential.

The company plots candidate opportunities on a two-axis map to apply those criteria: one axis runs from existing to new organizational capabilities, the other from existing to new markets and customers. Where a business idea already fits both existing capabilities and an existing market, it belongs to the company’s present position — domestic construction, overseas construction, real estate development, and green energy. Ideas that stretch into new markets or new capabilities are where the four emerging focus areas sit, alongside a fifth push aimed at transforming the construction business itself.

• Decarbonization
• City Platforms
• Space
• Agriculture and Biotechnology
• Construction Transformation (renewing the core construction business itself)

From idea to earnings: the innovation process

New initiatives are advanced under the leadership of Obayashi’s Business Innovation Division through a defined eight-step process, grouped into four stages, with projects selected through an internal application process open to employees.

Stage	Steps
Exploration	Generate ideas → Validate ideas
Validation	Validate client value → Validate solutions → Validate products and markets
Commercialization	Launch business
Monetization	Generate annual profit → Contribute to earnings

The structure is deliberately linear and gated: an idea has to clear client-value, solution, and product-market validation before it is allowed to launch as a business, and it is only considered a success once it is generating annual profit and contributing to group earnings. Obayashi also collaborates with Silicon Valley Ventures & Laboratory in the United States and its Singapore base to explore new business models and technologies, aiming to accelerate innovation globally — a way of pulling in outside ideas and partners rather than relying solely on internal proposals.

Three companies already spun off

Three group companies have already come out of this process, each addressing a different emerging-technology niche.

Company	What it does
Plibot	Provides centralized management of autonomous operations by connecting a wide variety of autonomous mobile robots — including indoor and outdoor transport and cleaning robots — with customers’ equipment through an integrated control platform
Oprizon	Japan’s first dedicated smart building service provider, jointly established with Hitachi Solutions; offers one-stop services covering construction, equipment, digital technologies, and systems for smart buildings
mitasun	Develops distributed data centers in urban areas by renovating and reconstructing existing buildings, addressing growing demand for urban data centers near edge-computing users while reducing the burden on existing power grids

All three read as extensions of Obayashi’s existing construction and facilities expertise rather than a clean break from it: Plibot applies the group’s operational know-how to robot fleet control, Oprizon pairs construction and equipment delivery with digital building systems, and mitasun repurposes existing buildings — construction and real estate skills again — into data-center capacity for the AI era.

What this means for investors

None of these three companies are broken out financially in the guide, and new business domains still sits inside the small ‘other businesses’ line in the group’s segment table — see the company overview for how that compares with the four established segments. What this page shows instead is process discipline: a defined set of selection criteria, an eight-step exploration-to-monetization pipeline, and three live spin-offs already through it. Decarbonization as a focus area also connects directly to the group’s dedicated green energy business, and the ‘vision, creation, and people’ language behind that first selection criterion draws on the same underlying capabilities the company sets out in more detail on its dedicated strengths page. The Accelerate Transformation phase of the Medium-Term Business Plan 2022 explicitly calls for generating new value for customers in new business domains, which makes this page the operational engine behind that later-phase strategic goal.
