Japan used to have one of the highest cryptocurrency tax rates in the world - up to 55%. If you made money trading Bitcoin or Ethereum there, the government could take more than half of your profit. That wasn’t just high - it was extreme. For comparison, stocks in Japan are taxed at a flat 20%. Crypto? You could pay over twice as much, no matter how long you held it. That’s why so many Japanese investors stopped trading locally and moved their activity overseas.
Why Did Japan Tax Crypto So Heavily?
Japan classified cryptocurrency as property, not currency. That meant every time you sold Bitcoin for yen, traded Ethereum for Solana, or bought coffee with Dogecoin, it counted as a taxable event. The government didn’t care if you held your crypto for one day or five years. Gains were added to your total income and taxed under the miscellaneous income bracket - the same bracket used for side gigs, freelance work, or rental profits.The tax system was progressive. If your total income (including crypto gains) was below 1.95 million JPY, you paid 5% national tax. But if you earned over 40 million JPY, the national rate jumped to 45%. Then came the local taxes: 10% on top of that, split between your prefecture and city. That’s how you got to 55% - 45% national + 10% local. No deductions. No holding period discounts. Just a steep, sliding scale.
And it wasn’t just big traders who felt it. Even someone making 500,000 JPY in crypto gains on top of a regular salary could jump into a 30%+ tax bracket. That’s why many people simply stopped reporting. The Japan Times reported a 32% drop in domestic crypto trading volume in 2023. Chainalysis found 27% fewer active Japanese wallet addresses on local exchanges between 2022 and 2023.
How the System Worked - And Why It Was a Nightmare
You didn’t pay tax when you bought crypto. You didn’t pay when you held it. You didn’t even pay when you moved it between your own wallets. But the moment you converted it to yen, swapped it for another coin, or spent it - boom, taxable event.Every transaction had to be tracked. Cost basis. Date. Value in yen. Exchange used. That’s a lot of data. And most people didn’t have it. Freee, a popular Japanese tax software company, found that 68% of crypto owners needed professional help just to file their 2023 returns. Koinly, a crypto tax tool, saw a 210% spike in Japanese users between 2022 and 2023. People were scrambling to keep up.
Exchanges had to play cop too. All licensed crypto platforms in Japan - like Coincheck, bitFlyer, and Zaif - were required to register as Crypto-Asset Exchange Service Providers (CAESPs). They had to collect KYC info, report user activity to the National Tax Agency, and keep records for seven years. If you traded on an unlicensed exchange? You were on your own. No help from the exchange. No audit trail. Just you, your spreadsheets, and a ticking clock before tax season.
Who Got Hit the Hardest?
It wasn’t just casual investors. Even serious traders with long-term portfolios got crushed. On Reddit’s r/CryptoJapan, users posted about annual gains of 10 to 50 million JPY. After taxes, they were left with less than half. One trader wrote: “I held Bitcoin for 3 years. I thought that would help. It didn’t. I paid 52%.”That’s the core problem: Japan didn’t reward patience. In the U.S., if you hold crypto for over a year, you pay lower long-term capital gains rates - as low as 0%. In Japan, a one-day trade and a three-year hold were treated the same. That killed the incentive to invest for the long term. It turned crypto into a speculative gamble, not a store of value.
And it pushed talent away. Developers, traders, and blockchain startups started moving to Singapore, Hong Kong, and Dubai. Japan’s crypto market shrank from 8.2% of the global market in 2021 to just 3.7% in 2024. Meanwhile, South Korea - with a flat 20% tax and clearer rules - grew its share to 6.1%.
The Big Change: Japan’s 20% Crypto Tax Reform
In December 2023, Japan’s ruling party announced a plan to fix this. After years of pressure from traders, economists, and even the Financial Services Agency, they agreed: the system was broken. On April 10, 2025, the FSA released a formal discussion paper titled “Review of Regulatory Frameworks for Crypto Assets.” Minister of Finance Katsunobu Kato said the goal was clear: make Japan a global hub for digital assets again.The solution? A flat 20% tax on all crypto gains - matching the rate for stocks. No more progressive brackets. No more 55% nightmare. The reform is scheduled to take effect in fiscal year 2026, meaning it will apply to trades made between January 1 and December 31, 2026, filed in early 2027.
It’s not just about lowering the rate. The new rules will also allow traders to carry forward losses for three years. If you lost money in 2026, you can offset it against gains in 2027, 2028, or 2029. That’s huge. It gives people room to breathe during market crashes - something the old system never offered.
What Stays the Same
The 20% rate is the headline, but the rules around reporting won’t disappear. You’ll still need to file your crypto income between February 16 and March 15 each year. The 200,000 JPY reporting threshold stays. If your total gains hit that mark, you’re required to declare them. Exchanges will still have to report your activity. The requirement to track every transaction - buys, sells, swaps - remains.And here’s the catch: Japan still won’t distinguish between short-term and long-term holdings. Even if you hold Bitcoin for ten years, you’ll still pay 20%. That’s different from the U.S. system, where long-term holds get lower rates. Some experts say this might still discourage true long-term investing. But compared to 55%? It’s a massive improvement.
What This Means for You
If you’re a Japanese resident: You’re getting a huge break. By 2026, your crypto profits will be taxed at the same rate as dividends or stock sales. That makes crypto look like a real investment again - not a tax trap. Expect more people to return to local exchanges. Analysts from Nomura Research Institute predict a 45-60% growth in Japan’s crypto market within three years. That could mean 1.2 to 1.8 million new retail investors and $4-6 billion in fresh institutional capital.If you’re a foreigner living in Japan: You’re already paying a flat 20% on crypto earned here. The reform doesn’t change your rate - but it makes the system fairer for everyone. No more confusion. No more unfair penalties.
If you’re outside Japan: This matters. Japan is one of the world’s most regulated crypto markets. When they move, others watch. The fact that they’re lowering rates and improving transparency signals a global shift. Countries that still tax crypto at 40%+ - like Germany or France - might feel pressure to follow. Japan’s reform could become a blueprint for how to balance innovation with control.
What’s Next?
The reform bill is expected to pass in Q2 2025. Once it does, exchanges will start updating their systems to reflect the new tax rules. Tax software will roll out new templates. The Tokyo Blockchain Association has already published updated guides for staking, DeFi, and NFTs under the new framework.The real test? Will Japan’s market bounce back? The numbers suggest yes. By 2027, experts predict Japan’s crypto market could hit $18-22 billion - reclaiming 5.5-6.3% of global market share. That would put it behind Singapore and South Korea, but ahead of the UK and Canada.
The 55% tax was a relic. It punished success. It drove away capital. It made Japan look out of touch. The 20% rate doesn’t make crypto tax-free - but it makes it fair. And in crypto, fairness is the most powerful incentive of all.

This is such a relief! I’ve been holding off on trading because of the old tax nightmare. 20% is finally fair. I’m moving my funds back to bitFlyer next month 🙌
Andrew Brady
This is just the government letting foreign capital in while screwing over Japanese citizens. They’re selling out our economy to Silicon Valley VCs. Mark my words - this will backfire.
Althea Gwen
so like... is this just capitalism finally admitting it’s broken? 🤔
Durgesh Mehta
this is good news for small traders like me i was thinking of moving to thailand but now i might stay
Sarah Roberge
I mean... if you think this is fair you’re not thinking deep enough. Taxing crypto at 20% is still punishing innovation. The real solution is zero tax. Always. Why are we even taxing digital assets? It’s not money it’s code. Code shouldn’t be taxed. 🤯
