Japan's FSA and police issued anti-fraud measures requiring withdrawal holds, pre-registered addresses, and faster freezes. A new cyberattack reporting template follows. Public comment open until Sept 7.
Japan's Financial Services Agency and the National Police Agency sent 11 anti-fraud steps to the country's crypto exchange association on August 6. The measures require exchanges to hold funds in flagged accounts for a set period before withdrawals can start. Users must pre-register destination addresses, and a cooldown period applies before transfers to newly added addresses can go through. Exchanges also need to set withdrawal limits based on customers' holdings and risk profiles.
Each exchange decides how to apply the controls based on its own operations and exposure, the FSA said.
The goal is to slow the movement of stolen funds off Japanese platforms. Once funds leave an exchange and land in wallets outside Japanese jurisdiction, recovery is near impossible. “We are tackling growing losses among crypto exchange users and cases where funds obtained through fraudulent schemes are being transferred to exchange accounts,” the FSA said in a statement.
A day later, the FSA published a separate draft revision standardizing how firms report cyberattacks and system failures. Crypto exchanges are among 17 sectors covered, according to CoinPost. Until now, a shared reporting template existed only for DDoS attacks and ransomware. The revision adds a new common template for other cyberattack incidents, following a May 2025 amendment to an inter-ministerial agreement. Firms can keep using the old format during a transitional period that runs through March 2027. The FSA is taking public comment until 5 p.m. on September 7.
The two moves land alongside a broader reworking of Japan's digital asset policy. On August 6, the FSA created a dedicated Crypto Assets and Stablecoins Division under a new supervisory bureau, replacing scattered office-level units that had handled the sector, Cryptopolitan reported. A law passed in July reclassifies crypto as a financial product under the Financial Instruments and Exchange Act, cuts the top tax on trading gains to a flat 20% from January 1, 2028, and lays the groundwork for domestic spot ETFs.
Public comment on the reporting template closes September 7.
