Cryptocurrency adoption and regulation continue to evolve rapidly across Asia, with Japan and South Korea standing out as two of the most influential markets. While both nations are technologically advanced and have active digital asset communities, their approaches to crypto policy differ significantly in key areas such as legal status, taxation, and regulatory frameworks. This in-depth analysis compares the cryptocurrency landscapes of Japan and South Korea, highlighting how each country balances innovation, investor protection, and financial stability.

Legal Status of Cryptocurrency
In Japan, cryptocurrencies are legally recognized as a form of payment. Since May 2016, digital assets like Bitcoin have been acknowledged under the amended Payment Services Act (PSA) as valid means of settlement. This landmark move positioned Japan as one of the first countries to formally accept crypto for transactions. The legal clarity was further strengthened in April 2017 when the PSA officially classified crypto assets as a legitimate payment method and introduced guidelines for exchanges and initial coin offerings (ICOs).
South Korea, on the other hand, has not granted legal tender status to cryptocurrencies. While widely used for investment and trading, digital assets cannot be used as a direct payment method in most real-world transactions. Since 2017, ICOs have been effectively banned due to concerns over fraud and market manipulation. However, following the collapse of Terra (LUNA) in 2022, South Korea signaled a shift by establishing the Digital Asset Committee, aimed at shaping comprehensive legislation and accelerating regulatory clarity for digital assets.
Despite differing stances, both governments recognize the growing importance of blockchain technology and are working toward structured oversight that supports innovation while minimizing risks.
Cryptocurrency Taxation Frameworks
Tax treatment plays a crucial role in shaping investor behavior and market participation. Japan treats cryptocurrency holdings as property, not currency. Gains from buying, selling, or trading digital assets are classified as miscellaneous income under the Income Tax Act. Individuals must report crypto-related profits if their annual gains exceed ¥200,000. Japan employs a progressive tax system, with rates ranging from 5% to 45%, plus an additional 10% resident tax—resulting in an effective tax rate between 15% and 55%.
South Korea applies a capital gains tax model specifically for crypto investments. As of 2023, long-term capital gains on virtual assets are taxed at rates from 6% to 24%, depending on profit levels. Short-term traders may face higher scrutiny, but investors who hold assets for over one year can benefit from preferential tax treatment. Additionally, income derived from mining or staking is subject to income tax based on activity level and earnings.
These contrasting models reflect broader fiscal philosophies—Japan’s inclusive income approach versus South Korea’s targeted capital gains strategy aimed at encouraging long-term investment.

Regulatory Framework in Japan
Japan’s crypto regulatory environment is among the most mature globally. The Financial Services Agency (FSA) oversees all crypto-related activities through key legislation including the Payment Services Act (PSA) and the Financial Instruments and Exchange Act (FIEA). These laws were updated in May 2020 to enhance consumer protection and strengthen anti-money laundering (AML) compliance.
To operate legally, cryptocurrency exchanges must obtain a Crypto Asset Exchange Service Provider (CASPS) license from the FSA. Licensed platforms are required to implement robust KYC (Know Your Customer) procedures, maintain secure custody solutions, and undergo regular audits.
Japan also pioneered self-regulatory organizations such as the Japan Virtual Currency Exchange Association (JVCEA) and the Japan Security Token Offering Association (JSTA). These bodies work alongside government regulators to promote industry standards, ensure transparency, and foster responsible innovation.
Japan’s proactive stance—being the first country to legally define "crypto assets"—has created a stable ecosystem where businesses can thrive within clear boundaries.
Regulatory Approach in South Korea
South Korea’s regulatory framework remains under development but is moving toward formalization. Although it lacks a unified legal definition for digital assets, the country enforces strict operational rules for exchanges. Key requirements include:
- Mandatory real-name bank account verification
- Prohibition of accounts for minors under 19
- Restrictions on foreign non-residents opening trading accounts
While these measures aim to prevent money laundering and protect vulnerable users, they highlight the absence of comprehensive legislation. To address this gap, the government launched the Digital Asset Committee in June 2022. Its mission includes setting listing standards for new tokens, outlining a potential path for regulated ICOs, and drafting the Digital Asset Basic Act (DABA).
Additionally, the Financial Supervisory Service (FSS) established the Virtual Asset Risk Monitoring Committee to identify systemic risks and recommend consumer safeguards. These initiatives signal a clear pivot from restriction to structured regulation.
President Yoon Suk-yeol has publicly supported deregulation efforts, pledging legal action against illicit crypto profits and advocating for victim compensation—a sign of growing political will to legitimize the sector.
Frequently Asked Questions
Q: Are crypto exchanges regulated in Japan?
A: Yes. All exchanges must be licensed by the FSA and comply with strict AML and cybersecurity standards.
Q: Can foreigners trade crypto in South Korea?
A: Non-resident foreigners are currently barred from opening accounts on domestic exchanges.
Q: What is DABA in South Korea?
A: The proposed Digital Asset Basic Act aims to establish a foundational legal framework for virtual assets, similar to Japan’s PSA.
