Strengthening Penalties for Unregistered Cryptocurrency Sales: What Has Changed? The cryptocurrency market, combining advanced technology and financial innovation, has established itself as a new economic hub, offering both opportunities and challenges to many investors and businesses. However, alongside its rapid development, this market also inherently carries uncertainty and risks, leading governments worldwide to progressively strengthen regulations to address them. Amidst this trend, Japan recently announced that it is preparing a legislative amendment to significantly strengthen penalties for the sale of unregistered cryptocurrencies, aiming to secure the soundness and stability of its crypto market. This move is expected to serve as a crucial milestone in cryptocurrency market management and have a significant impact not only on the Asian region but also on the global market. According to a Phemex report on March 16, 2026, Japan's Financial Services Agency (FSA) has unveiled a legislative amendment that substantially raises the maximum limits for imprisonment and fines to crack down on the sale of unregistered cryptocurrencies. The plan is to extend the current maximum prison sentence from less than 3 years to less than 10 years, and to increase the maximum fine from the existing 3 million yen to 10 million yen. This legislative amendment aims to enhance investor protection and is expected to be submitted to the Japanese Diet soon. This move demonstrates the Japanese government's strong commitment to maintaining cryptocurrency stability in the financial market and strengthening investor protection. Looking at the specific details of the penalty enhancement, the prison sentence will be strengthened by more than threefold, from less than 3 years to less than 10 years, clearly indicating the intent to treat the sale of unregistered cryptocurrencies as a serious crime. Fines will also increase by approximately 3.3 times, from 3 million yen to 10 million yen, which translates to a substantial increase from about 22 million won to about 74 million won in Korean currency. This robust penalty system is expected to exert a significant deterrent effect on illegal cryptocurrency sales. Through this amendment, Japan is moving towards substantially reducing illicit activities, ensuring market transparency, and integrating cryptocurrencies into the financial system. Indeed, the Japanese Financial Services Agency is simultaneously pursuing multifaceted policies to ensure the soundness of the cryptocurrency market. The strengthening of penalties for unregistered sales aligns with efforts to integrate the market into the institutional framework and is expected to contribute to eradicating illegal cryptocurrency activities, thereby enhancing market trust. Particularly noteworthy is that Japan is actively promoting the institutional integration of cryptocurrencies alongside strengthening regulations. Previously, the Japanese government classified cryptocurrency trading profits as miscellaneous income, applying a high tax rate of up to 55%. This has imposed a significant tax burden on crypto investors and has been cited as a factor undermining the competitiveness of Japan's cryptocurrency market. However, Japan has recently shown moves to significantly reduce the tax rate on 105 approved cryptocurrencies to 20% and reclassify them as financial products. This tax reduction measure is interpreted as treating cryptocurrencies on par with traditional financial products like stocks and bonds. A 20% tax rate is equivalent to the capital gains tax rate on stocks in Japan, which could be a significant turning point in recognizing cryptocurrencies as formal financial assets. However, these benefits apply only to the 105 approved cryptocurrencies. Unregistered cryptocurrencies will still be subject to high tax rates and now face even stronger penalties. This clearly demonstrates the Japanese government's intention to manage the cryptocurrency market through a 'carrot and stick' strategy. Japan's cryptocurrency regulatory policy is adopting a dual approach: gradually integrating cryptocurrencies into the institutional financial system while ensuring market transparency and stability through strict regulations. On one hand, it encourages legitimate transactions by granting tax benefits to approved cryptocurrencies, and on the other, it aims to remove unregistered cryptocurrency sales from the market through severe penalties. This approach is regarded as a balanced policy that simultaneously fosters the innovative nature of the cryptocurrency market while pursuing investor protection and market stability. Impact on Global Markets and South Korea? Looking back at Japan's history of cryptocurrency regulation, it was one of the first major countries to officially recognize cryptocurrencies, including Bitcoin, as a legitimate payment method through the revised Payment Services Act in 2017. At that time, Japan adopted a registration syst
