The cryptocurrency market in Japan has been established for 12 years where crypto was regulated mainly as a means of payment. In 2014, this made sense; regulation was needed to protect customers' funds following the<a href="https://en.wikipedia.org/wiki/Mt._Gox" rel="noopener noreferrer" target="_blank"> </a>Mt. Gox implosion — and limiting exchanges' ability to lose their customers' funds was the priority. However, fast forward to 2026: millions of Japanese retail investors own Bitcoin and other digital assets as an investment, rather than to spend them on coffee. On April 10, 2026, the Japanese cabinet passed an amendment to the Financial Instruments and Exchange Act (FIEA), which is the law governing both stock and bond trading. Under this amendment, digital currencies will be regulated in the same fashion as stocks and bonds. The FIEA amendment will now need to be passed by the Diet (Japan's legislature) before becoming law, and there have been no apparent objections from members of the Diet. With approval from the Diet, the new regulations would become effective starting in FY 2027.<h2>From Payments to Investments: Why the Shift Happened</h2>Coincidentally, However, at the time BTC was created, the original intention was that bitcoins would be used as a form of currency for transactions. Therefore, regulators needed to establish a framework for regulating the use of virtual currency by creating a law that focused solely on the transactional aspects of bitcoins and did not create regulations around the investment side of bitcoins. This lack of regulation relating to the investment aspect of bitcoins and blockchain technology has allowed for the continued growth and popularity of virtual currencies throughout the world. The<a href="https://www.sygna.io/blog/japan-crypto-regulation-history-2014-2020/" rel="noopener noreferrer" target="_blank"> </a>Payment Services Act (PSA) does not provide for any regulation of the investment side of bitcoin (and other cryptocurrencies), which has created a lack of regulatory oversight regarding the trading and issuance of cryptocurrencies. In the traditional equity markets, insider trading is criminal; however, in the Russian (or Japanese) virtual currency markets, there are currently no laws that prohibit insider trading, which has created an area of opportunity for any individual with prior knowledge of an upcoming project to trade and profit from that knowledge without any concern of being prosecuted.The FIEA amendment closes those gaps directly.<h2>What the New Rules Actually Say</h2>The bill introduces several concrete changes. Here's how the old and new frameworks compare: <table style="border:none;border-collapse:collapse" class="ql-table-better"><temporary class="ql-table-temporary" style="border:none;border-collapse:collapse" data-class="ql-table-better"> </temporary><colgroup><col width="201"><col width="224"><col width="200"></colgroup><tbody><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="1"> </td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="1">Previous Framework (PSA)</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="1">New Framework (FIEA)</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="2">Primary classification</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="2">Payment tool</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="2">Financial instrument</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="3">Insider trading rules</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="3">None</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="3">Banned</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="4">Issuer disclosures</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="4">Not required</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="4">Annual disclosures mandatory</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="5">Operator terminology</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="5">Crypto asset exchange business</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="5">Crypto asset trading business</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="6">Max prison term (unregistered)</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="6">3 years</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="6">10 years</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="7">Max fine (unregistered)</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="7">¥3 million</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="7" class="">¥10 million (~$62,800)</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="8">Tax rate on gains</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="8">Up to 55% (miscellaneous income)</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="8">Flat 20% (proposed separately)</td></tr><tr><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="9">NFTs and certain stablecoins</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="9">Covered under PSA</td><td style="vertical-align:top;padding:5pt 5pt 5pt 5pt;overflow:hidden;overflow-wrap:break-word" data-row="9">Remain under PSA</td></tr></tbody></table> This prohibition against illegal insider trading is already one of the rules on all Japanese stock exchanges. As before, no traders can use or obtain non-public information to assist them in their trading of cryptocurrencies. All cryptocurrency issuers will be required to provide annual financial statements which will place institutional investors, who previously had no means of performing due diligence, in a better position regarding reading the market. The increases in the penalties are also substantial. The increase from a maximum fine of 1 million yen (approximately 10,000 U.S. dollars) to 10 million yen (approximately 100,000 U.S. dollars) for unregistered operators is meant to send a strong message about the seriousness of government enforcement. Also, the maximum prison term for unregistered operators will be increased from 1 year to 3 years.<h2>The Tax Reform Running Alongside This</h2>Changes to the Financial Instruments and Exchanges Act (FIEA) do not directly address tax in Japan; however, both of these amendments are moving along a trend toward a broader vision for the future of Japan as an international investment hub. In Japan,<a href="https://coinpaprika.com/news/japan-crypto-tax-drops-20-2026-fiea-plan/" rel="noopener noreferrer" target="_blank"> </a>crypto gained income is taxed as miscellaneous income, with rates reaching up to 55% depending on the applicable tax bracket. This is NOT a typo! Back in Japan during the last cyclical bull in Bitcoin, a Japanese investor who would have experienced phenomenal gains could pay more than half of the profit from Bitcoin to tax. This led to a large amount of trading activity in the absence of a clear tax ruling on crypto assets, leading to a lack of long-term holding of crypto assets. The additional tax proposal will create a new tax rate on crypto gains in Japan of 20.315%, which is the same rate applied to capital gains on equity investments. Together with the FIEA amendments, this dual strategy makes Japan attractive to both retail investors and institutional capital that requires regulatory clarity relative to Japan before making long-term commitments to the Japanese market.<h2>What It Means for Institutions</h2>Japan's largest financial companies are getting ready to make moves in crypto. For instance,<a href="https://www.coindesk.com/policy/2026/01/26/japan-etfs-said-likely-to-trade-by-2028-as-sbi-nomura-ready-products" rel="noopener noreferrer" target="_blank"> </a>Nomura Holdings and SBI Holdings are expected to lead the way in creating investment products that involve cryptocurrency under the new law. Additionally, Japan is exploring possible ETF (exchange-traded fund) options for crypto currencies by 2028. This shift will create an underlying legal framework needed to allow these funds to operate under the same guidelines as other financial products. The change from naming these businesses "crypto asset exchange" to "crypto asset trading" is much more than a name change; instead, this change represents a legal shift in how these businesses will operate, moving more toward being a brokerage-type business than a payment processor-type business, which means they will have different compliance responsibilities (e.g. capital requirement changes) along with how they are allowed to partner with institutional clients.<h2>What Doesn't Change</h2>Not everything gets swept into the FIEA. NFTs and certain stablecoins remain under the PSA for now. The regulator appears to be drawing a line between assets used primarily for investment purposes and those with more functional or payment-focused characteristics — a distinction that will inevitably get tested as the lines blur. Japan has been building toward this for a while. Each regulatory update since 2017 pushed crypto incrementally toward mainstream finance. This amendment is the most direct statement yet that the experiment phase is over and the asset class is here to stay. Whether fiscal 2027 marks the actual start or slips further depends on parliament — but the direction is no longer in question.

Japan reclassified crypto as a financial instrument under the FIEA, banning insider trading, mandating annual disclosures, and raising penalties. A flat 20% tax rate runs alongside the reform.
