Key Takeaways

• The Bank of Japan is testing blockchain to make payments and securities settlements faster and more reliable across the banking system. 

• BOJ is experimenting with putting central bank money on a blockchain in a controlled sandbox to reduce delays, risks, and costs. 

• Japan is part of Project Agora, testing tokenized central bank money to make international payments clearer and easier to track.

The Bank of Japan is exploring whether blockchain could transform the way it does business. Speaking at Tokyo’s FIN/SUM conference on Tuesday, Governor Kazuo Ueda said the central bank is actively testing how blockchain and tokenization could change the way it processes payments and settles securities trades. These are the core operations that keep money and assets moving reliably between banks and financial institutions every day.

Ueda described the goal as building a “new financial ecosystem” and acknowledged that the BOJ is moving carefully. But his broader message was clear: staying on the sidelines is no longer an option. “Central banks need to adapt to how finance is evolving,” he said.

Testing the Future of Central Bank Money

One of the more ambitious parts of the BOJ’s plan involves putting central bank money itself on a blockchain. The bank intends to test blockchain-based settlements using the reserve accounts that commercial banks hold with the central bank, essentially the funds that sit at the heart of the financial system.

To do this safely, the BOJ is building a sandbox, a controlled testing environment where it can experiment with how central bank money would actually function on a blockchain. The goal is to make interbank transfers and securities settlements faster, cheaper, and less prone to delays that can ripple across the financial system.

Smart contracts could be a key part of making that work. These are self-executing programs that automatically carry out transactions once certain conditions are met, removing the need for manual processing and cutting down settlement times. Ueda said the BOJ wants to move carefully but collaboratively. 

“We want to move forward with the help of outside experts, exploring ways to link these new systems with the ones we already use, and testing practical applications like domestic interbank and securities settlements,” – Governor Kazuo Ueda

BOJ Embraces Tokenized Money With Project Agora

The BOJ’s blockchain experiments are not happening in isolation. Central banks around the world are wrestling with the same challenge: how do you modernize financial infrastructure built for a different era without disrupting the systems that people and businesses depend on?

Japan is an active participant in Project Agora, an initiative led by the Bank for International Settlements that brings together central banks to make cross-border payments faster, cheaper, and more transparent using tokenized money.

Ueda explained that the project is exploring whether central banks could issue their own money as tokenized deposits on a blockchain, with smart contracts automatically handling certain transactions. For international payments, which can currently take days and pass through multiple intermediaries, such automation could make a meaningful difference.

What This Could Mean for the Financial System

If the BOJ’s experiments pay off, the effects could ripple well beyond Japan’s borders.

• Faster Payments: Interbank transfers and international settlements that currently take days and pass through multiple intermediaries could be completed in a matter of hours. That shift alone could free up significant capital that is otherwise tied up while transactions are still in process. 

• Lower Costs: By automating transactions through smart contracts and reducing reliance on middlemen, blockchain-based settlements could lower the fees that banks and their customers pay when money crosses borders or changes hands. 

• Greater Transparency: Tokenized money leaves a clearer trail, making it easier for regulators and banks to monitor transactions in real time and flag problems before they spread through the system. 

• Future-Proofing Finance: As digital and programmable money become more common, central banks that have not tested and adapted their infrastructure risk being left behind. The BOJ’s work now is as much about staying relevant as it is about efficiency.

Ueda was clear that none of this would happen overnight. The priority is not speed of adoption but stability, and ensuring that whatever emerges can work alongside the financial systems already in place.

What a Digital Yen Could Look Like

The BOJ is also making quiet progress on a digital version of the yen for everyday use. Ueda confirmed that the central bank’s retail CBDC pilot is still running, with the BOJ testing the underlying infrastructure needed to support a digital currency that ordinary people and businesses could one day use for daily transactions. 

Running alongside the technical work is a CBDC Forum, where the BOJ is drawing on the knowledge of private sector players to help shape how such a system would function in the real world. 

The forum itself is set for a refresh. In its next phase, Ueda said the BOJ plans to widen the conversation beyond the technical nuts and bolts, bringing in broader questions about where payments are headed and what role a digital yen could play in that future, though no launch date is on the table yet.

Final Thoughts

The Bank of Japan’s blockchain experiments show that the country is ready to explore new ways of moving money. By testing tokenized central bank money, smart contracts, and faster settlements, the BOJ hopes to make payments simpler, cheaper, and more transparent. These trials also look at the future of a digital yen and how Japan can keep up with a world where digital money is becoming an everyday reality. While it will take time, these steps put Japan at the forefront of the move toward a more modern, efficient, and connected financial system.
