Japan’s Crypto Regulation Clarified as Viral 10-Year Prison Claim Debunked - Crypto Economy

TL;DR:

• Japan has no 10-year prison sentence in force for unregistered cryptocurrency sales, according to official FSA materials.
• The Payment Services Act sets a maximum of 3 years of confinement or a ¥3 million fine for operating without registration.
• The Financial Instruments and Exchange Act raises that ceiling to 5 years in prison or a ¥5 million fine for activities classified as securities.

Japan clarified that it does not contemplate a 10-year prison sentence for the unregistered sale of cryptocurrencies, according to publicly available materials from the Financial Services Agency (FSA). No bill, official notice, or legislative proposal before the Diet supports that figure. The claim is false, likely the product of misinterpretation or confusion with other offenses under Japanese law.

Current regulations establish considerably lower ceilings. Under the Payment Services Act (PSA), operating a cryptocurrency exchange without registration constitutes a criminal offense punishable by up to three years of confinement or a fine of up to ¥3 million. When crypto activities qualify as a securities business, the Financial Instruments and Exchange Act (FIEA) applies instead, raising the maximum to five years in prison or ¥5 million in fines, according to legal reports from firms such as Nishimura & Asahi.

Japan’s Regulatory Framework: What Operators Need to Know

The distinction between both laws is crucial for those operating in the sector. The PSA classifies unregistered activity under the category of confinement, a concept distinct from standard imprisonment in Japanese criminal law, and reflects the consumer protection criteria that guide that legislation. The FIEA, stricter on disclosure and registration controls, is triggered when the asset in question is assimilated to a traditional financial instrument.


The Japan Virtual and Crypto Assets Exchange Association (JVCEA) complements that statutory framework with self-regulatory standards for its member exchanges, adding a layer of industry oversight. According to an explanatory document by firm Arristor focused on consumer protection, “operating a crypto asset exchange without registration is punishable by confinement of up to three years or a fine of up to ¥3 million.”

For operators, overstating applicable sanctions can distort risk assessments and condition decisions on whether or not to seek registration. Compliance programs must be based on the texts of the PSA and FIEA as enacted, prioritizing official FSA sources, Cabinet ordinances, and Diet records over unverified secondary summaries.
