Speaking at FIN/SUM 2026 in Tokyo, Bank of Japan Governor Kazuo Ueda declared that blockchain technology has entered its “implementation phase,” with DeFi, smart contracts, and tokenized assets poised to alter payments, securities markets, and cross-border finance. In this developing environment where central bank currency could link divided networks and guarantee settlement finality, he stressed the central bank’s function as a “trust anchor.” The BoJ is aggressively investigating tokenized versions of central bank currency to smoothly fit into blockchain-based systems in order to accomplish this.
To test tokenized deposits of current accounts (reserves kept by commercial banks at the central bank), the BoJ has started a domestic sandbox project that allows 24/7 settlements for activities including domestic interbank transfers, securities transactions, and delivery-versus-payment (DvP). Japan is internationally engaged in Project Agorá, a BIS-led effort involving several central banks to create frameworks for issuing tokenized central bank deposits on blockchains, notably for effective wholesale cross-border payments with incorporated smart contract capabilities.
These initiatives fit with Japan’s bigger tokenization momentum including continuing retail CBDC trials for a digital yen as a foundational trust layer, together with artificial intelligence applications for blockchain data analysis in risk and compliance. While major players bring 24/7 tokenized stock trading — positioning central bank money at the heart of Japan’s digital financial infrastructure — institutions like Japan Post Bank are developing plans for DCJPY tokenized deposits by 2026 to support immediate transactions for digital securities and other blockchain assets.
