What to Know Before Considering Matsui Securities' Free Account Opening
What Tanaka first felt was the anxiety of "If I open an account, won't I have to start investing right away?" But in reality, opening an account and trading are separate steps. Matsui Securities' free account opening is positioned as the preparation stage for investing.
Matsui Securities is an online securities firm that provides brokerage and investment services to individual investors in Japan. Leveraging the strength of being an internet-only broker with no physical branches, it offers a wide range of financial products—including stocks, mutual funds, bonds, and foreign exchange margin trading (FX)—through its official website and smartphone app. Account opening is free and can be completed online.
The key point here is that opening an account itself costs nothing, and opening one does not obligate you to trade. Just as Tanaka decided to "start by gathering information," having an account in place first makes it easier to access the official website's investment insights and trading tools. It can serve as an environment for learning how investing works and understanding the risks involved.
That said, investing itself carries the risk of losing your principal. Stock and mutual fund prices fluctuate, and losses can occur depending on how your investments perform. A free account opening is merely the first step toward "having a place to learn"—careful judgment is required when it comes to actual trading.
In this way, Matsui Securities' free account opening functions as a foundation-building step before you begin investing. For those like Tanaka who "don't know which brokerage to open an account with," learning about the services offered by a major online broker first provides the information needed to decide whether it's the right fit.
Matsui Securities: Basic Information, Products, and How Fees Work
Next, Tanaka focused on two questions: "What can I buy?" and "How much will it cost?" In this section, we'll review the services Matsui Securities offers based on publicly available information.

Matsui Securities is an online brokerage founded in 1989, with a strong focus on online trading for individual investors. By operating without physical branches, the company has built a model designed to keep trading costs low, and its official website prominently advertises "free account opening."
Its product lineup includes domestic stocks, mutual funds, bonds, FX, and futures/options. Among these, the categories that beginners tend to care about most are stocks and mutual funds. Some mutual funds can be purchased for as little as 100 yen, making them popular as a way to build a diversified portfolio with small amounts. Stocks can be traded in real time, and orders can be placed through the smartphone app.
As for the fee structure, each product category uses a different pricing model. For stock trading, commissions may be charged based on the execution value, and campaigns are sometimes offered that waive fees when certain conditions are met. For mutual funds, expenses such as trust fees are set for each fund, and whether a purchase fee applies also varies by product. For FX, the spread (the difference between the bid and ask price) represents the trading cost.
These costs accumulate the more you trade and can affect your overall investment performance. For this reason, it's important to look beyond "is the fee low?" and consider whether the fee structure actually fits your trading style. If you're starting with a small amount like Tanaka, you should also pay attention to the minimum trading unit and any minimum fee thresholds.
Overall, Matsui Securities combines the convenience and low-cost focus typical of an online broker, while offering a product lineup that caters to a wide range of needs, from beginners to intermediate investors. Having an account with them gives you more options when you're ready to start investing.
Matsui Securities Account Opening: Comparison Table of Who It Suits and Who It Doesn't
Tanaka decided to compare Matsui Securities against other options to determine whether it's the right fit. To cut to the chase, Matsui Securities suits beginners who want to start investing online with small amounts. Let's review the reasons in the comparison table below.
| Comparison Axis | Matsui Securities | Other Major Online Securities | Bank-Affiliated Securities | Face-to-Face Securities |
|---|---|---|---|---|
| Range of Products | Broad: stocks, mutual funds, bonds, FX, etc. | Equally broad | Mutual funds are the core focus | Broad, but depends on the assigned advisor |
| Fee Structure | Online-focused with a low-cost approach | Varies by firm | Tends to be somewhat higher | Relatively high |
| Trading Tools & Apps | Mobile app supports order placement and information browsing | Varies by firm | Basic/simplified | Emphasis on face-to-face support |
| Support System | Online-centric, with phone support available | Varies by firm | Integrated with bank branches | Dedicated advisor handles each client individually |
| Account Opening | Free, fully completed online | Free and online is the norm | May be opened alongside a bank account | In-person visits may be required |
| Suitable Investment Style | Beginners who want to start small and handle everything online | Those seeking a wide range of options | Those who want to consolidate with their banking | Those who prefer in-depth consultation |
What emerges from the table is that Matsui Securities is highly beginner-friendly thanks to its "fully online, easy to start small" approach. Even compared with other major online brokers, the ease of free account opening and the usability of its app hold up well. Bank-affiliated and face-to-face securities firms offer the reassurance of having someone to consult, but they often fall short of online brokers in terms of fees and convenience.
That said, Matsui Securities isn't the best fit for everyone. Experienced traders with specific requirements for advanced tools or products should compare the finer details against other online brokers. Likewise, if you prefer in-depth, face-to-face consultations, the online-centric setup may not suit your needs.
Checking the details on the Matsui Securities official website will help you determine more concretely whether it matches your investment style. Account opening is free, and all you need to do is apply online. You can get started with the confidence of preparing to learn how investing works before you begin trading.
The Actual Account Opening Process and What You Need to Prepare
Tanaka-san braced himself, thinking "opening an account must be a hassle," but the actual process turned out to be simple. Here, we break down the general steps to opening a free account with Matsui Securities.

Opening an account with Matsui Securities is free, and the entire process can be completed online. There's no need to visit a branch — you can apply from home using your smartphone or computer.
Step 1: Start Your Application from the Official Website Visit the Matsui Securities official website and click the "Open Account" button to begin. Enter your contact details, such as your email address, to obtain an application ID.
Step 2: Submit Your Identity Verification Documents Upload official identity verification documents such as a driver's license, My Number card, or passport. In most cases, if you're using a smartphone, you can simply take a photo of the document and send it — that's all it takes.
Step 3: Enter Your Personal Information Fill in the form with your basic details, including your name, address, contact information, occupation, and investment experience. If there are no issues with the information you've entered, your application moves on to the screening stage.
Step 4: Screening and Account Opening Complete A screening is conducted based on the information you submitted, and once it's complete, you'll be issued a login ID and password. After your account is opened, you'll gain access to trading tools and investment information.
The time required varies from case to case, but if you have your documents ready, the process from data entry to application completion can be done quickly. Since it's a fully online process with no paperwork to mail in, even office workers who can't take time off during the day can easily complete it.
The essentials you'll need are an identity verification document and a financial institution account (for deposits and withdrawals) to use for investing. You may also be required to provide your My Number.
You can check the latest application status and accepted documents by visiting the Matsui Securities official website to review the account opening process. Account opening is free, and there's no obligation to trade. Opening an account is a reassuring first step toward learning about investing.
Risks and Points to Note When Using Matsui Securities (Loss of Principal and Costs)
As Tanaka-san finished preparing to open an account, he decided to take a fresh look at the risks involved in investing. This chapter outlines the risks and costs you should be aware of when using Matsui Securities.
There is no principal guarantee in investing. This is not unique to Matsui Securities—it is a fundamental principle that applies to all financial products, including stocks, mutual funds, and FX. Prices fluctuate based on market conditions and economic circumstances, and if the value falls below what you paid, you incur a loss. Even products with strong past performance do not guarantee future profits.
It is also important to understand the costs involved. Stock trading incurs commissions, mutual funds carry trust fees and purchase fees, and FX involves spreads. These costs accumulate the more you trade. While it is important to choose products with low fees or take advantage of campaigns, you should select products that match your investment goals and risk tolerance—not just the lowest cost.
An effective way to approach risk is to start small and learn how the mechanics work. Some mutual funds can be purchased with small amounts, and diversification helps reduce the risk of concentrating your exposure in a single stock. With stocks, you can build experience gradually by observing price movements.
Opening a free account is the first step in setting up this learning process. Opening an account does not mean you need to invest a large sum right away. It is important to use the investment information and tools provided after account opening, understand the risks, and act carefully.
Ultimately, Matsui Securities is best suited for those who want to learn how investing works with small amounts, those who want to complete the entire process online, and those who want to identify their own investment style before trading. The reasons are twofold: you can open an account for free, and you gain access to investment information and trading tools after opening.
Investing carries the risk of loss with no principal guarantee. It does not guarantee profits. Even so, as preparation for starting within your means after understanding the risks, opening a free account is well worth the first step.
