Wu Shuo learned that the Financial Services Agency of Japan, together with the Ministry of Land, Infrastructure, Transport and Tourism, the Police Department, and the Ministry of Finance, issued a document regarding compliance requirements for the use of crypto assets in real estate transactions, clearly stating that activities involving crypto assets and fiat currency exchange or intermediary matching may constitute crypto asset exchange services, and operating without registration poses legal risks. Regulatory requirements mandate that real estate industry practitioners strictly implement KYC, source of funds verification, and suspicious transaction reporting (STR), and report to regulators and police when unlicensed transactions or abnormal fund flows are detected. At the same time, cross-border crypto asset payments exceeding 30 million yen must fulfill reporting obligations.
