Japan has a unique position in global forex markets. While institutional players dominate in New York and London, Japan’s retail traders, who are often individual forex traders, account for a significant share of daily currency trading volumes. As a newer version was released globally, traders are slowly switching from MetaTrader 4 to its successor, MetaTrader 5.
At first glance, the transition may seem like a technical upgrade. But for brokers, technology providers, and market participants, it signals a shift in how retail FX traders see and trade the markets, what tools they demand, and how platforms evolve to meet those expectations.
Japan’s outsized role in retail forex—and why it matters
Japan has a very well-developed forex trading sector, which is also one of the largest and most active in the world. Retail traders can freely trade the markets flexibly due to the Tokyo trading sessions, enabling them to coincide their waking hours with the most active trading hours in the Asian season. This is flexible and is also among reasons why MetaTrader 5 adoption among Japanese forex traders is growing. The platform is a multi-asset trading platform that enables access to forex markets, cryptos, stocks, and more. This has become relevant after cryptos became part of mainstream broker offerings, and now any retail trader can freely trade digital currencies alongside traditional forex pairs.
Retail participation in Japan is both normalized and highly regulated. Brokers operate under strict oversight, leverage is capped for retail traders, and transparency requirements are strictly enforced. This has created a relatively stable environment where retail traders are active but not entirely speculative.
A platform transition years in the making
For more than a decade, MT4 was the sole dominant platform among forex traders due to its automated and manual trading capabilities and functions, which were almost never matched by other platforms. It has a user-friendly interface and comes with a multitude of built-in indicators. It also supports custom indicators and Expert Advisors for automated trading. All these features made it wildly successful and popular among retail traders, including both beginners and pros.
However, MT4 is no longer being actively developed by its studio, MetaQuotes. The company is mostly focused on the MT5 platform, which is the successor of MT4 and is slightly more advanced, designed to support a broad range of financial instruments and modern trading infrastructure. While MT5 is more advanced and less focus is on MT4, constant updates are still issued, meaning the platform is still useful and safe, just not as advanced as MT5 and has an older design.
In Japan, the transition has been gradual rather than sudden. Many traders remained loyal to MT4 due to familiarity and the vast ecosystem built around it. There are thousands of free tools like EAs and custom indicators, together with a huge library of educational materials to learn from. But over the past few years, momentum has been building in favor of MT5, driven by both broker adoption and changing trader expectations.
What MT5 adds—and why traders are paying attention
So, what does MT5 bring to the table, exactly? MT5 represents a broader expansion over MT4 in what retail trading platforms can offer.
First, MT5 supports multiple asset classes natively, without the need to add anything manually. This is different from MT4, which does not support stocks and cryptos natively. MT5 allows trading in stocks, indices, commodities, and even futures, all within a single trading user interface. For Japanese traders, who are trading several assets in their portfolios, this is a serious advantage.
Execution speed and infrastructure are improved as well. MT5 uses a more advanced architecture that supports faster order processing and even greater scalability. In a market where milliseconds can matter, especially for algorithmic traders, this is a noticeable upgrade.
Another advantage is MT5’s list of advanced analytical tools. It includes more built-in indicators, additional timeframes, and a more sophisticated strategy tester. Custom timeframes allow traders to use any chart time they want, which is a greater improvement. For traders who rely on data-driven decisions and EAs, these features provide a deeper level of insight.
Finally, MT5 supports a more modern approach to trading automation. While both platforms allow algorithmic trading, MT5’s programming language (MQL5) is more powerful and object-oriented than MT4’s MQL5. As a result, MT5 can enable more complex strategies and faster trade execution.
When taken together, these improvements add up to a significant upgrade in retail trading.
Brokers are accelerating the shift
While traders’ demand played a role, brokers have been more crucial in driving the transition to MT5, especially in Japan. Many brokers that operate inside Japan are now offering MT5 alongside, or in some cases even instead of MT4. New accounts are often encouraged and incentivized to start on MT5. These incentives often include lower spreads, improved execution speeds, or access to additional markets and instruments.
By migrating their traders to MT5, brokers can easily reduce long-term maintenance costs. At the same time, competition among brokers in Japan is fierce. Offering a more advanced platform is a way to try to differentiate services and attract clients who need sophisticated platforms. Japanese traders are known for their attention to detail, and they have to compete in an environment where even a little more advanced platform can mean the difference between losses and profits.
A signal for global markets?
Japan’s transition to MT5 is not an isolated, local case. It reflects a broader trend across the global retail trading landscape. As traders become more experienced and markets become more interconnected, demand is growing for platforms that can handle multiple asset classes and more complex strategies. The MT5 fits into this equation perfectly. For global brokers, the message here is super clear: platforms must evolve to meet changing expectations and respond to modern challenges.
Mobile trading is growing
The Mobile MT5 app is probably the number one trading app to access markets on the go. This is because it blends modern design with fast trade execution and advanced features like closing all open trades, all winning trades, or all losing ones. Together with many advanced features and tens of different built-in technical indicators, there are very few apps that can even come close to these features.
In the end, MT5’s rise to popularity among retail forex traders in Japan and across the world is supported by its advanced features, superior analysis and backtesting tools, and the availability of a most useful mobile trading app.
