🏛️ It took Japan eight years to answer a deceptively simple question: is Bitcoin money, or an investment? On July 15, the Diet gave its final answer. Crypto is now a financial product, regulated by the same law that governs stocks and bonds. The vote closes a chapter that began with a $530 million exchange hack — and it lands while Washington's own crypto bill sits frozen in the Senate.

The vote that ended an eight-year debate

Japan's upper house passed the amendment to the Financial Instruments and Exchange Act (FIEA) at its plenary session on July 15, with the ruling coalition and other parties supplying a comfortable majority. The bill had cleared the lower house on June 11 and the upper house Financial Affairs Committee the day before the final vote, completing a legislative run that started with cabinet approval on April 10.

The core of the law is a reclassification. Since 2017, Japan has regulated crypto under the Payment Services Act, which treats it as a means of payment — legally closer to electronic money than to a stock. That framing made Japan an early mover on exchange licensing, but it never fit how people actually use crypto. The Financial Services Agency's own surveys show the overwhelming majority of Japanese holders buy it hoping the price goes up, not to pay for groceries.

The push to fix that mismatch dates back to 2018, when hackers drained roughly 58 billion yen — about $530 million at the time — in NEM tokens from the Tokyo exchange Coincheck. The FSA convened a study group that year, applied securities law piecemeal to crypto derivatives in 2019, and finally proposed the full migration in late 2025.

The FSA positions crypto as a financial product distinct from securities. It sits inside the FIEA, but under its own tailored rulebook rather than a copy-paste of stock market regulation.

What changes the day the law takes effect

The biggest change: insider trading in crypto becomes illegal for the first time. Anyone with non-public information — a token's upcoming exchange listing or delisting, an issuer's new business plans — is barred from trading on it. The Securities and Exchange Surveillance Commission, Japan's market watchdog, gains criminal investigation powers and a monetary penalty system for the crypto sector, tools it has long wielded over the stock market.

Disclosure becomes mandatory too. Issuers of "specified crypto assets" must publish information once a year, ending the era when token projects traded on Japanese exchanges with no formal reporting duty at all.

And penalties get dramatically heavier. Selling crypto without registration currently carries up to three years in prison or a fine of up to 3 million yen (about $18,500). Under the new law, that jumps to ten years and 10 million yen (about $62,000). Exchanges also get a new name in the statute books: "crypto asset trading businesses" rather than "crypto asset exchange businesses," a small linguistic shift that mirrors the big conceptual one.

The 20% tax: the last domino is now lined up

For Japanese investors, the tax question has always been the one that matters most. Crypto gains are currently lumped in with salary as "miscellaneous income" and taxed at progressive rates that top out around 55%. Stocks, by contrast, enjoy a flat 20% rate.

The fix was actually legislated back in March, when the Diet passed a tax reform introducing a 20% flat rate (15% income tax plus 5% residence tax) for crypto, along with a three-year loss carryforward. But that law came with a precondition: it only activates once crypto legally becomes a financial product. July 15 cleared that condition.

The timing still requires patience. The tax switch applies from January 1 of the year after the FIEA amendment takes effect. With enforcement expected in fiscal 2027, the realistic start date for 20% taxation is January 1, 2028. Until then, the 55% ceiling remains the law of the land. "Japan passed the crypto law" headlines are easy to misread as "the tax already dropped" — it hasn't.

Which tokens qualify is also not fully settled. The government's stated direction is to cover all tokens handled by domestic registered trading businesses, but the precise scope will be pinned down in cabinet orders during the implementation phase. Trades on overseas platforms and decentralized exchanges are expected to stay outside the preferential treatment.

ETFs: the legal container finally exists

The amendment also builds the framework that lets crypto ETFs be created in Japan. As we covered in our earlier deep-dive on the ETF bottleneck, the obstacle was never a regulator saying no — it was that crypto wasn't on the list of assets a Japanese investment trust may legally hold. No container, no product.

That container now has a legal basis. Japan Exchange Group is reportedly eyeing listings around 2027. Once major financial institutions start building the products, institutional money that never had an entry point gets one — and many in Tokyo hope Japan repeats what the United States saw after spot Bitcoin ETFs launched in January 2024.

What is still blank paper

Passing the law settled the architecture. The interior design comes next, and it will take roughly a year of work on cabinet orders and supervisory guidelines. The open items are not trivial: how large the compensation reserves exchanges must hold against hacks, whether the current 2x leverage cap on crypto derivatives gets relaxed, what custody and anti-money-laundering requirements new entrants face, and exactly which tokens count as "specified crypto assets."

The law was not waved through without objection, either. In the upper house committee, the Japanese Communist Party voted against it, arguing that the state should not be steering household savings into crypto and that the bill leaves meme coins and decentralized exchanges under-regulated. The committee also unanimously adopted a supplementary resolution — a non-binding but politically weighty request that the government address such gaps as it writes the detailed rules. Compliance costs are a real concern too: smaller exchanges may struggle to meet securities-grade requirements, and some consolidation is widely anticipated.

Tokyo finished the race Washington is still running

The global context makes the timing striking. In the United States, the CLARITY Act — the market structure bill that would divide crypto oversight between the SEC and CFTC — passed the House in July 2025 by a wide margin, cleared the Senate Banking Committee in May, but has yet to reach a floor vote. It needs 60 votes, Democrats are demanding ethics provisions tied to the president's own crypto ventures, and analysts warn that missing the August recess could push the whole effort into 2027.

The EU moved earlier with MiCA, fully applicable since the end of 2024, but took a different route: a standalone, purpose-built crypto regime. Japan chose integration instead, folding crypto into the same statute that has governed its securities markets for decades — insider trading rules, criminal investigation powers, disclosure duties and all. Among major economies, that makes Japan's approach arguably the most complete fusion of crypto and traditional financial law to date, with the tax system redesigned in the same stroke.

Whether that translates into market growth depends on the rulemaking between now and enforcement, and on whether institutions actually show up when the ETFs list. But the direction is no longer in question. Japan spent eight years deciding, in law, that crypto is an investment.

How does your country treat it — as money, as an investment, or as something it still hasn't made up its mind about?
