What Sustainable Lab does

Sustainable Lab Inc. (サステナブル・ラボ株式会社) is a Tokyo-based private SaaS company that operates TERRAST, an AI-powered non-financial big data analytics platform focused exclusively on ESG and SDG data for the Japanese market. The company aggregates, structures, and analyzes ESG information from more than 2,000 Japanese listed companies, including approximately 50 million words of TOPIX500 integrated reports analyzed over two fiscal years, using natural language processing, text analytics, and predictive analytics to extract Scope 1/2/3 emissions, ESG KPIs, governance data, and disclosure language trends. It positions itself as Japan's only ESG/SDG-specialized non-financial big data collective, staffed by a multinational team with backgrounds in data science, sustainability, and financial engineering.

The product portfolio has expanded from a single ESG analytics tool into a suite of seven branded offerings: TERRAST for Enterprise (T4E) for SSBJ/CSRD compliance and integrated reporting; TERRAST for Management for financial institutions monitoring portfolio ESG data; TERRAST for Supplier for SME supply chain ESG data collection; a GHG Protocol-compliant Scope 1/2/3 calculation solution; a financial and non-financial analysis support service; and an AI-Friendly Sustainability Disclosure Support service that diagnoses and redesigns disclosure structures for machine readability. Core proprietary capabilities include the Momentum Keyword Analysis framework for annual ESG disclosure language trends and a peer comparison dataset for KPI benchmarking, both anchored to a multi-year Japanese disclosure corpus.

The company monetizes through annual SaaS subscriptions (custom-priced based on company size, scope, and user count) and professional services for CSRD/SSBJ advisory and disclosure support. Go-to-market combines direct enterprise field sales with channel and embedded distribution: NTT DATA serves as a strategic enterprise channel partner; Uniqus Consulting powers a co-branded "TERRAST powered by Uniqus" offering; regional financial institutions (Iwate Bank, Niigata Credit Guarantee Association) embed TERRAST inside sustainability-linked loan and credit guarantee products for SME borrowers. The firm holds ISMS certification (March 2025), is privately held with no disclosed funding rounds, and is led by founder and CEO Renji Hirase alongside COO Kotaro Takahashi and outside directors Yasuyuki Kato (former Nomura Securities Financial Engineering Research Center head, GPIF board member) and Tadasu Nakamura.
