Fujitsu Limited has announced the rollout of its FUJITSU Sustainability Solution Eco Track platform to support Mizuho Financial Group in strengthening human capital disclosure as part of its sustainability management framework. The SaaS-based service will go live in January 2026, expanding Fujitsu’s role in enabling data-driven ESG compliance for large financial institutions. As regulatory scrutiny around non-financial disclosures intensifies in Japan and globally, the partnership raises a key question: can standardized digital systems meaningfully reduce reporting complexity while improving the quality of human capital disclosures?

Strengthening Human Capital Disclosure Infrastructure

Eco Track is designed to support the collection, aggregation, and disclosure of non-financial data required for corporate sustainability management. In Mizuho’s case, the platform will enable centralized tracking of approximately 170 human capital indicators, including workforce diversity metrics such as the ratio of female managers and the share of managers hired outside Japan. The system aims to replace fragmented, manual data collection processes previously used across Mizuho’s domestic and international operations, which had led to inconsistencies and higher administrative burdens.

Japan’s decision to mandate human capital disclosure in annual securities reports for around 4,000 companies from March 2023 has accelerated demand for structured, auditable data systems. For complex financial groups like Mizuho, operating across multiple jurisdictions and subsidiaries, the challenge has been less about data availability and more about standardization and comparability. Fujitsu’s platform is positioned as a solution to harmonize definitions, workflows, and reporting formats across the group.

From Climate Data to Workforce Metrics

Mizuho’s adoption of Eco Track for human capital follows its earlier use of the platform to measure, aggregate, and visualize greenhouse gas emissions across Scope 1 and Scope 2 activities at domestic and overseas sites. According to Fujitsu, the expansion into human capital reporting was driven by the confirmed effectiveness of the system in handling climate-related data. This progression reflects a broader trend in sustainability management, where companies seek integrated platforms capable of handling both environmental and social datasets within a single governance framework.

By extending the same infrastructure to workforce data, Mizuho is effectively treating human capital metrics with the same level of rigor and visibility as emissions reporting. This alignment signals a shift toward viewing people-related data as a core component of enterprise risk management and long-term value creation, rather than as a purely qualitative disclosure.

ESG Compliance and Data-Driven Governance

Fujitsu is providing Eco Track under its Sustainability Compliance offering within the Uvance business model, which focuses on addressing societal challenges through digital solutions. The platform supports not only internal data management but also external disclosure, enabling companies to respond more efficiently to regulatory requirements, investor expectations, and stakeholder scrutiny.

For financial institutions, human capital disclosure is increasingly linked to assessments of governance quality, operational resilience, and long-term competitiveness. Standardized data collection can help boards and management teams identify gaps in workforce diversity, talent development, and succession planning, while also improving transparency to markets. In this context, digital disclosure tools may play a strategic role in translating ESG commitments into measurable and comparable outcomes.

Implications for Japan’s Disclosure Landscape

The partnership between Fujitsu and Mizuho illustrates how Japan’s evolving disclosure regime is driving demand for scalable ESG data infrastructure. As human capital reporting becomes embedded in securities filings, companies face rising expectations around accuracy, consistency, and auditability. Solutions like Eco Track may reduce compliance friction, but they also raise the bar by making workforce data more visible and comparable over time.

For Fujitsu, the deployment reinforces its positioning as a sustainability transformation partner for large enterprises, leveraging digital technologies to support non-financial reporting alongside traditional financial systems. For Mizuho, the initiative represents a step toward more integrated sustainability governance, where climate, human capital, and other ESG dimensions are managed through a unified data-driven approach.
