Japan reclassifies crypto assets as financial instruments: what awaits DeFi
Japan is initiating a large-scale regulatory reform that will shift crypto assets from under the Payment Services Act to the jurisdiction of the Financial Instruments and Exchange Act (FIEA). This represents a fundamental change in the status of digital assets—from a means of payment to an investment instrument. In my assessment, this adjustment reflects a global trend: cryptocurrency is increasingly perceived by the market as an asset class for long-term capital preservation and growth, rather than a medium for transactions.
Following the approval of spot Bitcoin ETFs in the United States, institutional ownership of the leading cryptocurrency has expanded rapidly. This has served as a catalyst for rethinking approaches to digital asset regulation worldwide. Japan, as one of the leaders in crypto regulation, has not stood aside. Under the new system, crypto assets will be classified as a separate category of financial products, paving the way for their full integration into traditional financial infrastructure.
What the Reform Changes
The new rules cover key aspects: disclosure requirements, combating market manipulation, insider trading, and enhanced oversight of service providers. These measures aim to increase transparency and investor protection—critical conditions for attracting large institutional capital.
For the decentralized finance (DeFi) sector, many open questions remain. Lawmakers have focused on those who actually control or influence users, rather than treating all market participants equally. Protocol developers, interface operators, wallet providers, DAOs, and token issuers may receive different sets of obligations. I believe this functional approach is the most sensible path: future regulation should be built around actual control and functions, not formal labels.
Enhanced disclosure standards, KYT-based oversight (tracking transaction origins), and DeFi models with identity verification could balance innovation and investor protection. This sets a precedent for other jurisdictions seeking a "sweet spot" between the freedom of decentralization and the need for legal certainty.
The Beginning of a New Era for Digital Assets
The transition to FIEA is not merely a change in regulatory label. The reform marks the start of a new phase in which digital assets become an integral part of Japan's broader financial system. Essentially, cryptocurrency is being equated in terms of requirements to traditional securities.
The Cabinet approved the bill on April 10, and the House of Representatives passed it on June 11. The document is currently under review by the House of Councillors, with enactment expected in 2027. However, self-custody of assets and many aspects of DeFi are not directly addressed in the current text and remain subject to subsequent regulations.
My analysis: Japan is once again setting the direction for the entire Asian region. This reform is a powerful signal to institutions: the crypto market is becoming "mainstream" within the traditional financial system. For DeFi, a time of "maturation" is approaching—it will have to adapt to new transparency standards, but in return, the sector will gain access to a vast pool of liquidity and trust from major players. 2027 is not far off, and preparation for the new reality must begin now.
