The CBDC Forum, established on July 20, 2023, brings together banks, payment operators, fintechs, and technology providers to advise the BOJ on how a retail digital yen could function in practice. The September meeting arrives at a pivotal moment: analysts and industry observers, citing reporting by Ledger Insights and Norbertgehrke.substack.com, expect a formal decision on whether to issue a digital yen before the end of 2026, with BOJ Governor Kazuo Ueda holding final authority on that call.

From Seven Working Groups to Three

The forum has undergone significant restructuring since its launch. Through March 2026, participating institutions had logged 84 working-level meetings and 163 company presentations across seven thematic working groups. By the Fifth General Meeting in March 2026, 33 institutions had flagged concerns about siloed discussions and unclear timelines. The BOJ responded by collapsing those seven groups into three Discussion Groups focused on practical implementation.

The three groups now cover CBDC architecture (ledger design, privacy, offline payments, and KYC integration), new technologies (distributed ledger technology, programmability, tokenized deposits, UTXO models, and AI agent payment compatibility), and ecosystem design (user access, cross-border use, API development, and competitive boundaries).

The reorganization marked a shift from theoretical research toward practical implementation engineering.

Pilot Hits Half the Speed Required

Japan's CBDC pilot, which began in April 2023, has produced concrete performance data that shapes the current technical agenda. The system has reached 50,000 transactions per second, split between 10,000 state-updating operations and 40,000 read-only balance inquiries. That figure is half the 100,000 TPS the BOJ has set as its national deployment target.

The pilot revealed that a single-ledger architecture cannot reach that threshold. A distributed multi-ledger system will be required instead. Testing also surfaced database lock-ups during high-frequency auto-charge and swing operations, momentary database disconnections, transaction spike failures, and synchronization delays between commercial bank core systems and the CBDC ledger.

The BOJ's working documents, as reported by FintechObserver, concluded that "no fatal technical flaws exist that would preclude an online retail CBDC," but the path to launch requires resolving these engineering problems.

The BOJ is also evaluating UTXO (Unspent Transaction Output), a transaction model used by Bitcoin, for applications requiring high privacy and compatibility with AI-driven payment agents. A public blockchain base has been ruled out due to scalability, privacy, and governance concerns.

The Japanese Bankers Association has signaled support for holding limits on digital yen balances, stating it has "no objection to the direction of suppressing the shift of funds from deposits...by setting an upper limit."

Holding caps would reduce the risk that households move large sums out of commercial bank deposits and into the BOJ's direct liability, which would constrain bank lending capacity, analysts note.

Policy Signals Point Toward Launch Preparation

Japan's Ministry of Finance convened its own 11th Expert Meeting on CBDC on June 25, 2026, releasing a progress report that outlined the division of responsibilities between public and private sectors and set a deployment roadmap. Analysts have described the report as a shift in official framing from whether Japan will issue a CBDC toward how it would do so. The BOJ's official position remains that issuance is not guaranteed.

Seiichi Shimizu, Director of Monetary Policy at the BOJ, said at the Forum's inaugural meeting in 2023 that the central bank must "leverage business expertise" to prepare for a possible launch decision, a framing that underscores why the 64-firm forum matters beyond a consultative role.

Why Emerging Markets Are Watching

Japan's digital yen architecture carries direct consequences for remittance corridors in South Asia and Africa. Japan is a significant source of remittances for migrant workers from India, Bangladesh, Nepal, and Sri Lanka. The BOJ participates in Project Agorá, a BIS initiative connecting seven central banks and more than 40 financial institutions, which achieved near-instant cross-border settlement in prototype testing in May 2026.

India's interest in Japan's interoperability architecture extends beyond bilateral remittances. At the 2026 BRICS Summit, India proposed linking member-state CBDCs for cross-border trade, and Japan's multi-ledger design could serve as a model for that framework.

A separate yen-pegged stablecoin called EJPY, developed by Japanese financial institutions and targeting international remittances, is advancing alongside the BOJ's retail CBDC work. Analysts have described EJPY as a direct complement to the digital yen programme, with both instruments addressing the same cross-border payment infrastructure.

For African fintech developers, the BOJ's rejection of public blockchain infrastructure as a CBDC foundation is a significant signal. Many ecosystem builders have assumed that DeFi-adjacent rails could eventually connect to sovereign digital currency systems. The BOJ's permissioned, multi-ledger architecture points in a different direction. Nigeria's eNaira, now in its third iteration, and Ghana's eCedi, currently in advanced pilots, are among the programmes for which the BOJ's architectural direction is directly material. Japanese diaspora communities from Nigeria, Ethiopia, and Kenya represent active remittance corridors that would be shaped by how cross-border digital yen interoperability is ultimately designed.

The geopolitical backdrop sharpens the stakes. A US Executive Order issued in January 2026 halted federal CBDC development, creating a policy vacuum that has shifted standard-setting responsibility toward the BOJ, the BIS, and the ECB. China's e-CNY had accumulated 16.7 trillion yuan in cumulative transactions through November 2025, while India's digital rupee pilot had reached 7 million users. Japan's permissioned, multi-ledger approach represents a pragmatic middle path between China's aggressive rollout and the US withdrawal from the field. African central banks now choosing which CBDC architecture to align with are watching the BOJ's year-end decision closely.

Japan's e-payments market is projected to reach $227 billion. The BOJ's final decision, expected within months, will determine whether digital yen becomes a layer within that market or remains a pilot indefinitely.
