What IDEA Consultants does

IDEA Consultants (いであ株式会社, TSE: 9768) is a publicly traded Japanese environmental and construction consulting firm founded in 1953 and headquartered in Setagaya, Japan, with 1,001-5,000 employees. The company operates four core business divisions: Environmental Consulting (environmental impact assessment, natural environment preservation, chemical analysis and risk evaluation, life sciences, and sustainability management consulting); Construction Consulting (national land conservation, transportation and logistics infrastructure, urban and regional planning, and disaster response and recovery); Information Systems (disaster prevention, rainfall forecasting, flood prediction, customized weather and bioclima services, AI/IoT/big-data DX solutions, and metaverse-based disaster support); and Overseas Business (infrastructure management and environmental conservation aligned with UN SDGs, primarily in Asia).

The company's technology stack rests on proprietary systems developed over decades, including water-air combined drones with acoustic positioning for underwater infrastructure inspection, integrated weather and flood prediction platforms fed by long-running hydrological and meteorological data assets, image and video analysis for infrastructure and environmental detection, and AI/IoT/big-data analytics layered on top of consulting workflows. Patent and utility model applications back several of these tools, and NETIS registrations position them for Japanese public-sector procurement.

Revenue is generated through project-based professional services contracts negotiated with public-sector and enterprise clients; pricing is quote-based and not publicly disclosed. The primary customer segments are Japanese national and local government agencies and infrastructure/construction enterprises, with secondary segments in international development organizations and food/life sciences. Sub-brands such as BIOWEATHER SERVICE and ideacon life care extend the firm into recurring information services and consumer-facing channels. Go-to-market is direct enterprise and government field sales, with distribution predominantly domestic complemented by regional overseas delivery in Asia and Southeast Asia.
