Bank of Japan Expands Blockchain Sandbox for Settlement and Bank Deposits

Bank of Japan Governor Kazuo Ueda reveals a new blockchain experiment aimed at integrating blockchain into interbank settlements and stablecoin integration for deposits.

Fact Check
Both the Japanese and English versions of the Bank of Japan's speech, officially published on its website, explicitly discuss the institution’s examination of blockchain technologies and the potential for tokenized forms of central bank money related to current account deposits. The materials show that these efforts are part of research and exploration, rather than operational implementation, directly supporting the statement’s claim that the Bank of Japan is conducting research or exploration into the tokenization of current account deposits. The sources are primary, authoritative, and consistent, with no contradiction or ambiguity found between them.
