Japan's crypto overhaul and the widening gap with the US: what to watch

Headlines in recent weeks have called Japan the next world crypto hub, nudging the US aside. The actual picture is more restrained. Tokyo has enacted a notable law under which Bitcoin and around 104 other crypto assets are treated more as securities than payment instruments. Yet the two shifts that could most plausibly attract new capital — spot crypto exchange-traded funds and a reduced tax rate — are still pending. The US remains far bigger for now.

What Japan's new legislation does

Parliament in Tokyo gave the final nod on 15 July to a statute that shifts crypto out of the Payment Services Act, where it had been handled mainly as a means of payment. Digital assets now sit under the Financial Instruments and Exchange Act, the statute that controls equities and debt securities.

In practical terms, this imports stockmarket-style obligations: insider-trading bans, disclosure duties and tougher enforcement against firms operating without registration. Stablecoins and NFTs remain under the earlier payments regime.

The core measures have not come into operation yet. They will start on a date the Cabinet picks, no later than a year after the law's publication.

Taxes, ETFs and the timing

For most Japanese traders, the key issue is how gains are taxed. At present, crypto profits are treated as miscellaneous income, with high earners paying as much as 55%. The incoming system applies a flat 20% levy, the same as equities, to qualifying tokens disposed of via registered firms. It further permits losses to be carried forward for three years.

Taxpayers should expect the reduced rate to apply from 1 January 2028. If the new statute takes effect during 2026, the rate could land a year sooner, on 1 January 2027.

Spot crypto ETFs are a longer way off than recent coverage implies. The legislation passed in July does not authorise them by itself; Tokyo has yet to rewrite its investment trust act before such a product can debut. Finance Minister Satsuki Katayama has described 2026 as the opening year of a digital era and cited US crypto ETFs as a template. Citing a template, however, is not approving a product.

Reasons behind Japan's shift

Japan's regulatory framework has grown out of past disasters. Mt. Gox, the exchange that once processed most of the world's Bitcoin trades, went under in 2014 following the loss of 850,000 BTC. That prompted Japan to be among the first nations to license crypto exchanges, starting in April 2017. Each subsequent breach brought stricter requirements:

• Coincheck's 2018 loss came to about $534 million.
• DMM Bitcoin sustained a loss of 48.2 billion yen in 2024.

This backstory continues to shape policy, with stability and oversight taking priority over rapid expansion:

• Foreign platforms are pulling out. In August, Bitget said it would stop serving Japanese residents, after Bybit had already left following cautions from the Financial Services Agency (FSA), the country's financial watchdog.
• The watchdog is reorganising. A separate FSA unit covering crypto assets and stablecoins was created in August.
• On-chain finance has become a stated priority. The FSA in September identified on-chain finance — payments, settlement and tokenised assets conducted on blockchains — as a policy focus.
• Major banks are part of the experiment. MUFG, Mizuho and Sumitomo Mitsui — Japan's three biggest banking groups — are testing stablecoins within the new regime.

Japan versus the US

The home market in Japan is hardly small: active users top 12 million, and exchange balances exceed 5 trillion yen. The US competes on another scale. By the close of September, American spot Bitcoin ETFs alone had roughly $108 billion in net assets.

Japan's impact on Bitcoin's price has likewise been modest. CryptoQuant, an on-chain data provider, concluded in an analysis last year that Japan's small portion of global Bitcoin holdings explains this.

More accurately, Japan is trying to become Asia's most tightly supervised significant crypto market, offering a believable base of operations for institutions and banks. That goal has real relevance, yet it does not amount to leapfrogging the United States.

What to watch from here

• Start date. The Cabinet still has to choose when the law becomes effective. If it begins in 2026, the 20% tax rate would move up to January 2027.
• Investment trust legislation. That is the strongest hint about whether a spot Bitcoin ETF is on the way. Without the amendment, Japanese investors have no route into crypto ETFs comparable to the one available in the US.
• Token eligibility. The FSA's specifics will determine which assets qualify for the reduced rate. This in turn will guide where Japanese trading tends to cluster.
• Yen stablecoins. If bank-issued yen stablecoins shift from pilots into actual use, that would signal Japan's "regulated first" model is building momentum.

Speed is what would alter the outlook. A rapid passage of the trust act change, followed by a spot Bitcoin ETF, could turn Japanese investment through domestic funds into a measurable stream of flows. Japan would then deserve watching alongside US ETF figures. Before that, the reforms look more like a long-term structural narrative than an immediate influence on Bitcoin's price.
