The Japan Virtual and Crypto Assets Exchange Association (JVCEA) oversees self-regulation, though experts report it remains weak. The new framework seeks to explicitly prohibit trading using nonpublic or undisclosed information.

The agency is also examining how virtual assets can be treated similarly to securities, aiming to strengthen investor protection.
