Japan may be approaching a major turning point in finance. One key theme is “on-chain finance.”

As Chair of the DeFi Committee at the Blockchain Collaborative Consortium (BCCC), I have advocated for the adoption of DeFi and on-chain finance, as well as a regulatory framework that enables responsible innovation.

On-chain finance means issuing, managing, transferring and settling financial assets—such as money, deposits, securities and bonds—on blockchain networks. Its real potential, however, is not simply tokenization. It is the ability to connect commerce and finance through programmable infrastructure.

For example, once delivery and inspection are confirmed, a smart contract could automatically trigger stablecoin payment and update accounting records. Commerce, payments and accounting could become one continuous digital process.

For this to scale in Japan, five conditions are critical:

1. Move from regulations that allow experiments to rules that enable commercialization.

2. Treat stablecoins as programmable money, not merely digital payment instruments.

3. Connect banks and DeFi rather than viewing them as competitors.

4. Make blockchain invisible to users through simple, familiar UX.

5. Measure success by commercialization, transaction volume and cost reduction—not the number of PoCs.

Japan already has financial institutions, major corporate markets, advanced payment infrastructure and an evolving regulatory foundation.

The next challenge is execution.

The future of finance is not simply digital. It is programmable. Japan’s opportunity is to connect finance, industry, data and AI on-chain—and turn experimentation into real economic infrastructure.
