Nikken Sekkei Research Institute

What Nikken Sekkei Research Institute does

Nikken Sekkei Research Institute (NSRI, 日建設計総合研究所) is a Tokyo-based private consulting and research firm founded in 2006 as the think tank of the Nikken Group, with Nikken Sekkei (株式会社日建設計) as its parent entity. Operating from its headquarters in Chiyoda-ku, NSRI provides project-based engineering and management consulting services at the intersection of urban design and architectural environmental engineering, with a stated mission of contributing to sustainable society. The firm employs 51-100 staff organized around energy management, ESG strategy, carbon neutrality (GX), public-private partnerships (PPP/PFI), urban planning, urban DX/data utilization, and mobility services.

NSRI's core analytical product is the Walkability Index (暮らしやすさ指標), a proprietary metric quantifying livability by facility density and variety within a 15-minute walking radius, with scoring models tailored by household type (family, single, senior). This is complemented by the みどりのものさ (Five Green Value Indicators) covering cooling, biodiversity, water management, mental health, and carbon sequestration; CEMS (Community Energy Management System) deployments at district scale; ZEB (Zero Energy Building) design guideline development; and AI-integrated real estate valuation via a partnership with PriceHubble Japan. Recent productization (May 2026) combines the Walkability Index with PriceHubble's AI appraisal and Price Map to deliver an Affordability Index for urban areas.

The firm's revenue model is professional services on a project quotation basis — fees are determined per engagement scope and are not publicly disclosed. Clients are concentrated in three primary segments: (1) national and municipal government agencies (MLIT, Tokyo Metropolitan Government, Yokohama City, Kariya City) for policy, planning, and certification work; (2) private real estate developers and corporations (Mitsui Fudosan, Keikyu, Minato Aquls, Tokyo Skytree Town, Tokyo Garden Terrace Kioicho) for energy management, ESG strategy, and carbon neutrality roadmaps; and (3) universities (Tokyo University, Keio, Kansai, Hokkaido) for campus carbon neutrality planning. Distribution is direct consulting engagement with no channel intermediaries, supported by thought-leadership marketing through a corporate website, the monthly Headline News and semi-regular VIEW newsletters, the NIKKEN FORUM symposiums, and active academic conference participation.

Broad incumbents

• Takenaka Corporation: Major Japanese architecture, engineering, and construction firm with sustainability and ZEB-focused research capabilities. Overlaps with NSRI in building environmental engineering and carbon-neutral building consulting, but as part of a vertically integrated construction business.
• Mori Building Co. Tokyo-based urban developer (Hills series) with in-house sustainability research and smart city initiatives. Competes with NSRI for urban planning, walkability, and district-scale energy management mandates, but as a developer rather than a pure research/consulting firm.
• Kajima Corporation: Major Japanese construction and real estate developer with an internal research institute (Kajima Technical Research Institute) covering sustainable buildings, ZEB, and ESG. Overlaps with NSRI in building environmental engineering and ESG consulting, but as part of a much broader construction business.

The most direct incumbent in NSRI's niche but at much greater scale and with design/construction capabilities beyond research consulting.
• Obayashi Corporation: Major Japanese construction firm with in-house sustainability and environmental engineering research capabilities. Competes with NSRI for sustainability consulting mandates at scale, though primarily serving its own construction projects and selected external clients.
