Japan is set to introduce sweeping reforms to its cryptocurrency regulations, including a ban on insider trading, as authorities move to treat digital assets more like traditional securities. The new measures, led by the Financial Services Agency (FSA) and the Securities and Exchange Surveillance Commission (SESC), are expected to take effect by 2026.
Under the proposed framework, trading cryptocurrencies based on non-public or privileged information will become a criminal offence. According to Nikkei Asia, the SESC will be empowered to investigate violations, impose fines, and refer serious offences for prosecution. Those found guilty could face significant penalties, including surcharges on profits earned through illicit trades—similar to existing enforcement under Japan’s securities laws.
To define the scope of insider trading in the crypto market, the FSA plans to establish a dedicated working group before the end of 2025. Examples likely to fall under the new rule include trading tokens before a public exchange listing or exploiting undisclosed security flaws for financial gain. Crypto exchanges will also be mandated to tighten compliance systems, improve transparency, and adopt internal controls to prevent misuse of confidential information.
Japan’s crypto industry has expanded rapidly, with over 7.8 million active trading accounts recorded as of August 2025—nearly four times higher than five years ago. Regulators say this surge underscores the need for stricter investor protection and market integrity.
Currently, crypto oversight in Japan largely depends on self-regulation by exchanges under the Japan Virtual and Crypto Assets Exchange Association. The upcoming reforms aim to transfer oversight from the Payment Services Act to the Financial Instruments and Exchange Act (FIEA), aligning crypto assets more closely with traditional financial products.
By enforcing these changes, Japan hopes to harmonize its regulations with global standards amid growing scrutiny from U.S. and European authorities over crypto market manipulation. The initiative signals Tokyo’s commitment to fostering a transparent and trustworthy digital asset ecosystem while maintaining investor confidence.
