The Bank of Japan (BOJ) has officially launched the first phase of its central bank digital currency (CBDC) proof-of-concept (PoC) testing, marking a significant step in the nation’s journey toward a potential digital yen. Announced on April 5, this initial phase will run through March 2022 and focuses on evaluating the technical feasibility of core CBDC functions such as issuance, circulation, and exchange. This move reflects a broader global trend, as central banks worldwide accelerate their digital currency initiatives amid shifting economic dynamics and rising demand for modernized financial infrastructure.

The Three-Stage Roadmap for Japan’s Digital Yen
The BOJ’s approach to CBDC development is structured into three distinct phases. The current first phase centers on backend system design and technical validation, ensuring that foundational elements like transaction speed, security, and scalability meet national standards. No public-facing features or user participation are involved at this stage.
In the planned second phase, the focus will shift to functional enhancements—most notably, whether to impose holding limits on individual users or institutions. This economic design consideration aims to prevent large-scale bank disintermediation while promoting equitable access.
The third phase, if initiated, would involve real-world pilot programs with payment service providers and end users. Such trials are crucial for assessing usability, consumer behavior, and integration with existing financial platforms.
Although the BOJ emphasizes it has no immediate plans to issue a digital yen, officials stress that proactive experimentation is essential for preparedness. Shinichi Uchida, an executive director at the bank, stated during a committee meeting: “We don’t have plans to issue a CBDC now, but launching these tests is a necessary step forward.”
Historical Context and International Collaboration
Japan’s exploration of digital currencies dates back to 2016 when the BOJ partnered with the European Central Bank on Project Stella, a joint initiative to assess blockchain applications in cross-border payments. Over four research phases completed by February 2020, the project evaluated settlement efficiency, privacy mechanisms, and system resilience—providing valuable insights for future CBDC architecture.
In October 2020, the BOJ released a comprehensive report outlining its strategic vision for a potential digital yen. It highlighted growing public demand driven by rapid technological change and underscored the importance of maintaining payment system stability and efficiency. The report also detailed key design considerations: dual-tier distribution (central bank + private sector), privacy safeguards, interoperability, and anti-money laundering compliance.
Meanwhile, private-sector innovation has already taken root. Rakuten Group launched Rakuten Wallet in 2019—an app enabling users to trade Bitcoin, Ethereum, and fiat currencies—demonstrating market readiness for digital asset integration.
Global Momentum: From Caution to Acceleration
Prior to 2020, many advanced economies approached CBDCs cautiously. Former ECB President Mario Draghi dismissed plans for a digital euro in 2018, while BOJ Governor Haruhiko Kuroda echoed similar sentiments in 2019. However, the global pandemic acted as a catalyst, exposing inefficiencies in legacy payment systems and accelerating digital transformation.
By May 2020, the U.S.-based Digital Dollar Project published its white paper proposing a framework for a digital dollar. In March 2021, Federal Reserve Chair Jerome Powell affirmed that the Fed would engage the public on digital currency issues during the year, noting that congressional authorization would likely be required.
Similarly, the European Central Bank released its Digital Euro Report in October 2020, signaling openness to issuing a digital euro if deemed necessary. Japan’s concurrent release of its CBDC report underscores a coordinated shift among major economies.
According to Liu Bin, Financial Research Director at the China (Shanghai) Pilot Free Trade Zone Research Institute, “The pandemic revealed gaps in national payment infrastructures. Countries now see CBDCs not just as technological upgrades but as strategic tools to maintain monetary sovereignty in an increasingly digital world.”
Core Challenges Ahead for Japan’s CBDC
Despite progress, several critical challenges remain before a digital yen could become reality:
1. Architecture Design: Retail vs. Wholesale Models
The BOJ must decide whether to pursue a retail CBDC (accessible to individuals and businesses) or a wholesale model (limited to financial institutions). Based on its 2020 report, Japan appears inclined toward a retail system with indirect issuance via private intermediaries—similar to China’s DCEP model. This approach preserves the role of commercial banks while enabling broad access.
2. Technology Selection
Will blockchain form the backbone of the digital yen? Or will hybrid or centralized ledger technologies be used? The choice impacts scalability, energy consumption, and regulatory oversight.
3. Cross-Border Interoperability
For Japan—a major trading nation—ensuring compatibility with other nations’ CBDCs is vital. Participation in global standard-setting bodies like the Bank for International Settlements (BIS) will be key to achieving seamless international transactions.
4. Use Case Development
Unlike China’s mature mobile payment ecosystem (e.g., Alipay, WeChat Pay), Japan still relies heavily on cash and legacy card systems. Encouraging adoption requires compelling use cases: micropayments, government disbursements, or integration with smart city infrastructure.
Liu Bin notes: “Japan wants to stay competitive in the global CBDC race. Its goal isn’t just modernization—it’s securing influence in shaping future financial standards.”
Frequently Asked Questions (FAQ)
Q: Is Japan planning to launch a digital currency soon?
A: Not immediately. While testing has begun, the BOJ has no firm launch timeline. Any rollout would depend on successful trials and policy decisions.
Q: Will the digital yen replace cash?
A: No. The BOJ intends to maintain cash as legal tender. The digital yen would serve as a complementary payment option.
Q: How does Japan’s CBDC compare to China’s digital yuan?
A: China leads in deployment with active pilots across multiple cities. Japan is still in early technical testing but shares similar goals: financial inclusion, efficiency, and monetary sovereignty.
Q: Could individuals lose privacy with a digital yen?
A: The BOJ has committed to balancing traceability for regulatory purposes with strong privacy protections for small-value transactions.
Q: What impact could CBDCs have on banks?
A: If too many deposits shift to central bank accounts, commercial banks may face funding pressures. Holding limits could mitigate this risk.
Q: How might CBDCs affect cryptocurrency markets?
A: While CBDCs are state-backed and distinct from decentralized cryptos like Bitcoin, their rise validates digital money concepts—potentially increasing mainstream acceptance of blockchain-based assets.
