In Japan, the law requires anyone trading crypto assets (virtual currencies) to use a crypto asset exchange service provider registered with the Financial Services Agency (FSA). This article explains the basic thinking behind Japan's regulations in general terms, focusing on three pillars: the registration system, segregated management of customer assets, and user protection.
Crypto asset prices can fluctuate sharply, and you could lose part or all of your principal. There are also risks such as exchange hacks and the failure of a service provider. Understanding the regulatory framework can help you grasp these risks, but it does not guarantee any profit.
Regulation Began with the 2017 Amendment to the Payment Services Act
Cryptocurrency regulation in Japan originated with amendments to the Payment Services Act, which took effect on April 1, 2017. At that time, the assets were called "virtual currency" (virtual currency), but through subsequent amendments and the development of Cabinet Office Ordinances, the term "crypto-assets" (crypto-assets) has become the common name.
Even today, businesses that operate crypto-asset exchange services are fundamentally subject to regulation under the Payment Services Act. These businesses are required to register, and they must establish systems to protect users and provide appropriate information.
Why It Matters to Use an Exchange Registered with the Financial Services Agency
When buying or selling crypto assets in Japan, users are required to use a crypto asset exchange service provider registered with the Financial Services Agency (FSA). If you use an unregistered operator, the administrative oversight and user protection mechanisms may not fully apply, and you may have limited options for recourse if problems arise.
Even when using a service provided by an overseas operator, the treatment may differ depending on whether the service is offered to residents of Japan. Before using any service, it is important to verify its registration status, for example through information published by the FSA.
What Is Segregated Asset Management?
Segregated asset management is a system in which assets held on behalf of users, such as cryptocurrencies and Japanese yen, are kept separate from the operator's own assets. Its purpose is to make it easier to protect users' assets even if the operator runs into financial trouble.
In general, methods such as storage in an environment not connected to the internet (cold wallets) are used to hold the majority of users' assets. However, segregated management does not guarantee that every yen or unit of crypto is fully protected. The extent and method of protection depend on each operator's structure and disclosures.
Investor Protection Framework and Its Limits
The investor protection framework includes disclosure of risks before trading, provision of information on contract terms and fees, and the establishment of systems for handling complaints. Operators have a duty to conduct their business in good faith toward their users.
However, regulation has its limits. It does not prevent cryptoasset price fluctuations themselves, and the possibility of losses from hacking or trading suspensions caused by system failures cannot be reduced to zero. In addition, transactions outside the scope of regulation, or those conducted overseas, may not be covered by Japanese protections.
Developments Regarding Compliance with the Financial Instruments and Exchange Act
Crypto assets are currently regulated mainly under the Payment Services Act. However, reports indicate that, given their growing nature as investment products, consideration is underway to bring them within the scope of the Financial Instruments and Exchange Act.
This point reflects an ongoing regulatory reform process, and it cannot yet be stated as a settled fact. It is important to check future amendments and official announcements from the Financial Services Agency and the government directly against primary sources.
Points for Users to Check
Before using crypto assets, it's wise to confirm the following points.
- Whether the provider you plan to use is registered with the Financial Services Agency (FSA) of Japan
- Whether you have checked the latest information on fees, trading conditions, and withdrawal methods on the official website
- How the provider explains its segregated asset management and information security measures
- Whether you have checked with a professional or the tax authorities, since tax treatment varies by country and region
For comparisons between providers, resources such as Crypto Exchange Comparison may be helpful, but in all cases, prioritize the latest official information.
Summary
Japan's crypto asset regulation rests on three pillars: the registration system for providers registered with the Financial Services Agency (FSA), the segregation of customer assets, and the framework for protecting users. These are important safeguards for users, but they do not completely eliminate risks such as price volatility, provider risk, and hacking. Regulations may be revised over time, so it is important to check the latest official information and make decisions that match your own risk tolerance.

Frequently Asked Questions
When buying crypto in Japan, how should I choose a provider?
Japanese law requires you to use a crypto asset exchange service provider registered with the Financial Services Agency (FSA). You can check registration status in the FSA's published information. Review each company's official website for the latest fees and trading terms.
If my crypto assets are segregated, are they fully protected?
Segregated management means your assets are kept separate from the provider's own assets. However, this alone does not guarantee full protection. The methods and scope of safekeeping vary by provider, so it is important to review each company's disclosures.
What happens if I use an unregistered overseas exchange?
Unregistered providers may fall outside the reach of Japan's administrative oversight and user protection frameworks, which can make it harder to obtain redress if problems arise. Before using any service, confirm whether it is intended for Japanese residents.
Will crypto assets eventually fall under the Financial Instruments and Exchange Act (FIEA)?
Media reports say discussions are progressing toward including crypto assets under the Financial Instruments and Exchange Act (FIEA), but nothing has been finalized. Check primary sources, including the latest legal amendments and official FSA announcements.
