ESG compliance in Japan: a guide for SMEs
Japan has made TCFD-aligned climate disclosure mandatory for large listed companies and is rolling out the GX (Green Transformation) strategy to decarbonise its economy. Japanese corporations are among the most active requesters of supplier ESG data globally — making Japan a high-priority jurisdiction for any SME in a Japanese supply chain.

The regulatory landscape
- Mandatory TCFD reporting — Japan's Financial Services Agency (FSA) requires TCFD-aligned climate disclosures for all companies listed on the Prime Market of the Tokyo Stock Exchange (TSE) from FY2023. This is one of the broadest mandatory TCFD requirements in the world.
- GX (Green Transformation) Strategy — Japan's national decarbonisation plan introduces a carbon pricing mechanism and requires large emitters to participate in an emissions trading scheme from 2026. Supply chain emissions (Scope 3) are a key focus.
- Corporate Governance Code — TSE-listed companies are expected to disclose sustainability information, including climate risks and human capital. The 2021 revision explicitly requires Scope 3 disclosure for Prime Market companies.
- Act on Promotion of Resource Circulation — requires businesses to reduce waste and improve resource efficiency, with reporting obligations for large companies.
Supply chain obligations
Japanese corporations are globally recognised for the depth of their supplier ESG programmes. Companies like Toyota, Sony, and Panasonic have comprehensive supplier codes of conduct and require annual ESG data submissions from their supply chains — often using platforms like EcoVadis or their own proprietary questionnaires.
If you supply to a Japanese company, expect requests for:
- Scope 1, 2, and 3 greenhouse gas emissions data
- Energy consumption and renewable energy percentage
- Labour practices, working hours, and health and safety data
- Anti-corruption and governance policies
- EcoVadis score or equivalent third-party rating
Practical priorities for Japan-facing SMEs
If you supply to a TSE Prime Market-listed Japanese company, check their supplier ESG requirements. Most have published supplier codes of conduct with specific data requirements.
Begin tracking Scope 1 and 2 emissions. Japanese buyers are among the most likely to request full Scope 3 data, which requires your own emissions as a starting point.
Consider obtaining an EcoVadis rating. Japanese MNCs frequently use EcoVadis as a standardised supplier assessment tool.
Monitor Japan's GX carbon pricing mechanism. If you manufacture in Japan or have Japanese manufacturing partners, carbon costs will affect your supply chain pricing.
