Japan is entering a fascinating chapter. A country that has been at the forefront of integrating blockchain technology into its everyday economy may soon allow its largest banks to invest directly in Bitcoin. This is not a spontaneous decision, but rather the result of discussions at the Financial Services Agency (FSA), which analyzes changes in the law. At the same time, three powerful financial institutions are planning a joint attack on the stablecoin market. Let’s take a closer look at this, as these moves could change the dynamics of global cryptocurrency markets.
Bitcoin in bank wallets. From prohibition to possibility
Until recently, Japanese banks had to stay away from non-stablecoin cryptocurrencies like Bitcoin. The 2020 FSA guidance made this clear. Too much risk, too much volatility. But times are changing. The agency is now considering reforms that would open the door to acquiring and holding such assets as part of an investment portfolio. This is not only a gesture towards diversification, but above all a recognition that cryptocurrencies are maturing as an asset class.
Why now? The market in Japan is growing rapidly. At the end of February this year, the number of cryptocurrency accounts exceeded 12 million. This is an increase of more than 3 times in five years. FSA, aware of this trend, does not want to lose its advantage. Discussions at the Financial System Council meeting on October 15, 2025 highlighted the need for balance. Innovation yes, but under strict control. Exposure limits are planned, banks will not be able to allocate more than a certain percentage of capital to Bitcoin, and higher capital requirements are planned to protect the stability of the financial system. This is a pragmatic approach that allows for experimentation without systemic risk.
Stablecoins from giants. Fast payments for companies
In parallel to the bitcoin plans, the three largest banking groups in Japan, Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Financial Group (SMFG) and Mizuho Financial Group, are joining forces in a stablecoin project. The idea is to issue stablecoins linked to the yen, dedicated to corporate payments. This is not a loose idea, but a specific plan based on the amendment to the Payment Services Act of 2023, which gave the green light for such instruments.
The technology behind it is fintech Progmat Inc., which will ensure interoperability. That is, smooth transfers of funds between clients of different banks. Initially, they will focus on the yen, but a version linked to the US dollar is also planned. The first tester will be Mitsubishi Corp., with rollout later this fiscal year. Imagine blockchain settlements that shorten transaction times and lower costs, especially in international transfers. For Japanese companies, it is a chance to reduce bureaucratic shackles, and for the entire ecosystem, of course, a step towards mass adoption.
Broader context and perspectives
These initiatives are not isolated events. The FSA is also considering allowing banking groups to register as cryptocurrency exchange service providers, which will further integrate traditional finance with digital assets. More broadly, Japan is positioning itself as a leader in controlled innovation. Unlike chaotic markets in other countries. For global investors, this is a signal that cryptocurrencies are entering the mainstream, with the blessing of large regulators.
Of course, there are challenges. Bitcoin price volatility remains a concern, and stablecoins need to prove their reliability in real-world scenarios. But if these plans pan out, we could see a wave of similar movements in Asia and beyond. Japan, with its history of precision and discipline, shows that cryptocurrency adoption does not have to be a revolution, just an evolution. It is worth following these events because they shape the future of our portfolios.
