Japan Cracks Down on Crypto: New Rules to Ban Insider Trading

By ToTo BugelmanNewcomer0 rep· 10/15/2025

Japan is set to implement new regulations aimed at banning and penalizing cryptocurrency insider trading, bringing digital asset markets in line with traditional securities regulations. The move by the Financial Services Agency (FSA) and the Securities and Exchange Surveillance Commission (SESC) seeks to enhance investor protection and market integrity.

Key Takeaways

  • Japan's financial regulator is drafting new rules to explicitly ban cryptocurrency insider trading.

  • Violators will face fines based on illicit profits and potential criminal referrals for serious offenses.

  • The regulations aim to align crypto market oversight with existing securities laws.

  • The framework is expected to be finalized by the end of 2025, with proposed amendments to the Financial Instruments and Exchange Act (FIEA) submitted next year.

  • The crackdown addresses the growing number of crypto users in Japan and aims to curb market manipulation.

 

Expanding Regulatory Powers

The SESC will be empowered to investigate suspicious trading activities within the cryptocurrency space. Currently, the Financial Instruments and Exchange Act (FIEA) does not explicitly cover crypto assets for insider trading, leaving a regulatory gap. The proposed amendments will grant the SESC the authority to impose surcharges on violators, calculated based on their ill-gotten gains, and to make criminal referrals in more severe cases. This initiative aims to bolster investor confidence and ensure a more secure trading environment.

 

Framework Development and Challenges

The FSA plans to finalize the details of this new regulatory framework by the end of 2025. A proposed amendment to the FIEA is slated for submission to parliament next year. A significant challenge identified by regulators is the difficulty in defining who constitutes an "insider" in the crypto market, as many digital assets lack identifiable issuers. Despite these complexities, Japanese authorities are working to establish clear definitions and investigation procedures to effectively address insider trading.

 

Growing Market and Future Outlook

This regulatory push comes as Japan has seen a substantial increase in cryptocurrency adoption, with the number of local users quadrupling to 7.88 million over the past five years. The government's broader strategy includes placing crypto regulation under the FIEA to strengthen investor protection and combat issues like inaccurate disclosures and unregistered operations. With potential political shifts favoring technological development, Japan aims to foster innovation while maintaining rigorous financial governance standards.
