Japan warned lagging on-chain finance threatens economic security and monetary sovereignty

Japan’s former Minister for Digital Transformation, Takuya Hirai, has issued a stark warning that the country’s slow adoption of on-chain finance — including stablecoins, tokenized deposits, and real-world asset (RWA) tokenization — could undermine its economic security and monetary sovereignty. The statement, posted on X, follows discussions within the ruling Liberal Democratic Party’s (LDP) Digital Headquarters, which has designated finance as its 18th growth sector and is pushing for accelerated development of on-chain financial infrastructure through public-private partnerships.

Hirai’s warning: a structural shift in global finance

Hirai, who served as Japan’s first Minister for Digital Transformation, described a fundamental structural shift in the global economy. He argued that artificial intelligence and blockchain technology are converging to create an automated, interconnected system for the economy, finance, and payments. In this new foundation, transactions, settlements, and financing are unified, with AI agents handling real-time decision-making.

“A structural shift is underway where AI and blockchain are creating an automated, interconnected system for the economy, finance, and payments,” Hirai wrote on X. He warned that as dollar-based stablecoins become more widespread, competition for leadership in financial infrastructure is intensifying. If Japan falls behind in this trend, he cautioned, it could have direct consequences for the nation’s economic security and its ability to maintain monetary sovereignty.

LDP Digital Headquarters pushes on-chain finance agenda

The LDP Digital Headquarters has now designated finance as its 18th growth sector, signaling a formal push to integrate blockchain-based financial instruments into Japan’s regulatory and economic framework. The proposal under discussion centers on stablecoins, tokenized deposits, and the on-chain tokenization of real-world assets (RWA). These technologies aim to bring traditional financial instruments — such as bonds, real estate, and commodities — onto blockchain networks, making them more liquid, programmable, and accessible.

Japan has already taken early steps in regulating stablecoins. In June 2023, the country passed legislation recognizing stablecoins as a form of digital money, requiring issuers to be licensed and to maintain full backing in yen or other fiat currencies. However, Hirai’s comments suggest that these initial moves may not be enough to keep pace with the rapid global evolution of on-chain finance, particularly as the United States and other jurisdictions accelerate their own regulatory frameworks.

Why this matters for Japan and global markets

The warning from a former high-ranking official carries weight in Japan’s policy circles. Hirai was instrumental in establishing Japan’s Digital Agency in 2021 and has been a vocal advocate for digital transformation across government and industry. His focus on the link between on-chain finance and national security reflects a growing recognition among policymakers that digital financial infrastructure is not just a technological upgrade but a strategic asset.

Japan’s economy, the third-largest in the world, has traditionally been cautious in adopting digital assets and blockchain technology. While the country has a robust regulatory framework for cryptocurrencies, the pace of innovation in on-chain finance has been slower compared to the United States, Singapore, and the European Union. If Japan fails to build competitive on-chain financial infrastructure, it risks losing influence over global financial standards and could see capital and talent flow to more progressive jurisdictions.

The LDP’s Digital Headquarters plans to accelerate development through public-private partnerships, aiming to create a regulatory environment that encourages innovation while maintaining financial stability. The proposal includes exploring the use of stablecoins for domestic and cross-border payments, tokenizing government bonds and other public assets, and developing common standards for on-chain finance.

Conclusion

Japan’s on-chain finance debate is no longer a niche technology discussion — it is now a matter of national economic security. Takuya Hirai’s warning, combined with the LDP Digital Headquarters’ formal push to develop on-chain infrastructure, signals a potential shift in Japan’s approach to digital finance. The coming months will reveal whether Japan can translate its early regulatory moves into a competitive on-chain financial ecosystem or whether it will fall behind in the race for leadership in the global financial infrastructure of the future.
