Japan's Financial Services Agency, in collaboration with the Ministry of Land, Infrastructure, Transport and Tourism, the National Police Agency, and the Ministry of Finance, has issued new compliance guidelines for the use of cryptocurrencies in real estate transactions. The document clarifies that activities involving the exchange of cryptocurrencies for fiat or acting as intermediaries may constitute a crypto asset exchange business, which requires registration to avoid legal risks.Real estate professionals are mandated to strictly implement Know Your Customer (KYC) procedures, scrutinize the sources of funds, and report suspicious transactions (STRs). Additionally, they must notify regulators and law enforcement of any unlicensed trading or unusual fund flows. Cross-border crypto transactions exceeding 30 million yen must also be declared.
