The Bank of Japan will test blockchain technology for settling deposits that financial institutions hold at the central bank, Governor Kazuo Ueda, the central bank’s leader since 2023, outlined the initiative during the FIN/SUM 2026 conference in Tokyo today.
The initiative is part of a sandbox project designed to examine the use of central bank money for multiple settlement activities, including domestic interbank and securities transactions.
Internationally, the BOJ has participated in Project Agorá, an experiment with multiple central banks and financial institutions to develop tokenized central bank deposits, which could streamline cross-border payments.
The project has brought together multiple central banks and major financial institutions to explore how smart contracts and atomic transactions could streamline international payments. Under the proposed framework, participating central banks would issue tokenized versions of their reserves on distributed ledgers.
The governor noted that distributed ledger technology has moved beyond experimentation into active deployment across financial services. He pointed to DeFi protocols as evidence of blockchain’s high programmability.
The BoJ launched a retail digital currency pilot in 2023 to assess technical requirements for issuing digital cash, though no decision on a public rollout has been made. Japan’s persistent preference for physical currency has shaped the cautious approach.
Ueda emphasized the need to ensure interoperability as multiple blockchain networks emerge alongside traditional payment rails. Without central bank involvement, he warned, users might perceive value differences between payment instruments on separate systems.
The governor also highlighted potential synergies between artificial intelligence and distributed ledgers, citing AI-driven advisory services and automated collateral management as emerging applications that could draw on transaction data stored on-chain.
