"20 million yen is needed for retirement." Every time Kenta Sato, a 35-year-old employee at an IT firm in Tokyo, saw headlines like this, he felt a deep unease. With a child entering elementary school next year and a mortgage that still has many years left to run, he wondered if a comfortable life in the future was truly achievable on an annual household income of 6 million yen. Although plagued by anxiety, he hesitated to take concrete action, thinking, "Investing seems scary," or "Won't I lose money on fees?"
Conclusion: Matsui Securities' iDeCo stands out primarily because it charges no administration fees and offers up to 40 investment products—one of the largest selections in the industry—including the popular "eMAXIS Slim All-World Equity" fund. For salaried workers seeking to build retirement savings efficiently at low cost, it represents one of the most realistic options available.
A 35-Year-Old Confronts Retirement Anxieties: The Journey to Discovering iDeCo

Kenta first became aware of iDeCo (Individual-type Defined Contribution Pension) during a casual lunch conversation with a colleague. "Your entire monthly contribution is tax-deductible from your income, and investment gains are tax-exempt. There's no reason not to do it," his colleague said. Prompted by this, Kenta did some research on his own, but he hesitated again when he encountered the restriction that funds "cannot generally be withdrawn until age 60."
iDeCo is a private pension system where individuals make contributions and invest them in pre-selected products such as investment trusts or fixed-term deposits. The full amount of contributions is eligible for income deduction, reducing the burden of income tax and residence tax. Furthermore, profits earned during the investment period are tax-free, and upon withdrawal, they qualify for retirement income deductions or public pension deductions.
However, his mind was plagued by worries: "What if the investments don't perform well?" or "What if I need the money before retirement?" He came across reviews on several sites stating, "Since relying solely on the national pension was worrying, I'm glad I took the approach of investing," which reassured him that he wasn't alone. Nevertheless, overwhelmed by the sheer volume of information regarding which financial institution to open an account with and what assets to buy, he found himself unable to take action.
Three Reasons Why Matsui Securities iDeCo Is Chosen—Fees, Products, and Points
The turning point came during an online drinking session with a friend from university. "Matsui Securities' iDeCo has zero account management fees. Plus, you can buy popular funds like eMAXIS Slim." Skeptical at first, Kenta opened his smartphone and checked the official Matsui Securities website. There, he found the three clear advantages he had been looking for.
1. Zero Account Management Fees For iDeCo, each financial institution sets an "account management fee," which directly impacts long-term investment costs. In the case of Matsui Securities, this account management fee is completely free. Note that a total monthly account management fee of 171 JPY, paid to the National Pension Fund Association and the trust bank, is required regardless of which financial institution you choose. If you contribute 10,000 JPY per month for 30 years, the difference becomes significant if another company charges several thousand yen in annual fees. "Even small amounts add up over time. With zero fees, that money can go straight into investments," Kenta realized, feeling positive about starting iDeCo for the first time.
2. Choose from Up to 40 Products, Including a Robust eMAXIS Slim Lineup Matsui Securities' iDeCo boasts a lineup of 40 mutual funds. A major advantage compared to other providers is its extensive selection of 13 funds from the low-cost "eMAXIS Slim" series. In particular, the "eMAXIS Slim All-World Equity (All-Country)" fund is widely supported by everyone from beginners to advanced investors because it allows for diversified investment in stocks around the globe. "Being able to choose well-known, highly-rated funds reduces the anxiety of making a poor product selection," Kenta felt.
3. Earn Up to 1% Points Back on iDeCo Mutual Funds At Matsui Securities, you can earn points every month worth up to 1% of your iDeCo mutual fund balance. While iDeCo is generally perceived as something that incurs fees, a point-back system is a rare feature. However, receiving these points requires a monthly entry operation, and detailed conditions can be confirmed on the official website. "It feels like a bit of extra effort, but if I can do it in a few minutes on my smartphone, there's no reason not to," Kenta thought positively.
Seeing this information firsthand significantly shifted Kenta's perspective. "With zero fees, access to famous funds, and even point rewards, there might be no reason not to start."
Latest 2026: Comprehensive Comparison of Major Online Securities for iDeCo—Costs, Product Lineup, and Support
"But is Matsui Securities really the best choice?"—Kenta decided to research other online brokers as well. To make a fair comparison, he gathered information on SBI Securities, Rakuten Securities, and Monex Securities and summarized them in the table below.
| Comparison Item | Matsui Securities | SBI Securities | Rakuten Securities | Monex Securities |
|---|---|---|---|---|
| Account Management Fee (incl. tax) | ¥0 | ¥0 | ¥0 | ¥0 |
| Number of Mutual Funds Available | Approx. 40 | Approx. 85 | — | — |
| Number of eMAXIS Slim Funds Offered | 13 | — | 0 | 6 |
| eMAXIS Slim All-World Equity Fund | ○ | × | × | ○ |
| Point Rewards | Up to 1% (Entry Required) | — | Rakuten Points | — |
| Phone Support | 365 Days | — | — | — |
| Fund Workshop (Robo-Advisor) | ○ | — | — | — |
Faced with this comparison table, Kenta's decision became almost certain. While SBI Securities offers a larger number of products, it does not carry the "eMAXIS Slim All-World Equity Fund," which he most wanted to purchase. Rakuten Securities boasts attractive integration with the Rakuten ecosystem, but the inability to buy his target fund remains a major drawback. Although Monex Securities offers the fund, the limited selection of eMAXIS Slim funds gives the impression of lacking variety.
In the end, Kenta firmly concluded, "Fees and product availability are the deciding factors. Matsui Securities, which offers the eMAXIS Slim All-World Equity Fund and has the lowest account management costs, aligns perfectly with my investment philosophy."
As a result of comparing multiple securities firms, Matsui Securities clearly holds the advantage for the goal of accumulating popular funds at low cost. Why not open a free account today and start preparing for your future at your own pace?
Real Insights from Reviews—Robust Support and Honest Feedback
Kenta was curious about how others using Matsui Securities' iDeCo actually felt, so he checked several review sites. Among the 145 reviews posted on Yahoo! Finance, the majority were positive or neutral, indicating that the service is generally well-received.
Looking at the actual comments, praise for the support system and ease of use stands out.
"Although phone inquiries are only available on weekdays, I can get through immediately even during lunch hours. The support staff is also very helpful." (From a comparison site)
"The website is easy to use, and the methods for investigating issues and contacting support when questions arise are clear." (From a review posting site)
"The application process was simple, and I was able to open an account easily." (From another review site)
Reading these comments eased Kenta's anxiety that "the procedures might be difficult." On the other hand, he also honestly checked the complaints users have expressed.
A common concern is that "having to register every month to receive point rewards is a hassle." Additionally, some users feel that "there are so many products that beginners may struggle to choose."
However, Kenta thought about these points calmly. Monthly registration can be completed in just a few minutes via smartphone, and even if forgotten, it does not affect the investment itself. Regarding product selection, Matsui Securities offers support tools such as "Fund Workshop," a robo-advisor, and an "iDeCo Simulator." If unsure, users can also ask questions via phone support available 365 days a year.
Even if there is some minor effort involved, considering the long-term cost benefits and the high quality of the products, it is well worth it. Convinced of this, Kenta finally decided to move forward with opening an account.
Getting Started with Matsui Securities iDeCo Without Confusion—From Application to Launch
Kenta opened his laptop on the living room table and accessed the official Matsui Securities website. The actual account opening process was surprisingly simple.
Step 1: Access the Application Page on the Official Website First, open the dedicated iDeCo page on the Matsui Securities website and click the "Open an Account Here" button. Then, simply follow the on-screen instructions to enter your information.
Step 2: Prepare Required Documents and Fill Out the Application Form Have identification documents ready, such as a driver's license or My Number card. Since Kenta researched the requirements beforehand, the process went smoothly.
Step 3: Submit Documents by Mail or Online Once you finish entering your details, either take photos of your identification documents with your smartphone and upload them, or submit them by mail. Afterward, a review is conducted by organizations such as the National Pension Fund Association. This review typically takes several weeks.
Step 4: Start Making Contributions After Opening Your iDeCo Account Once your account is successfully opened, set your monthly contribution amount. With Matsui Securities iDeCo, you can start accumulating assets with as little as 5,000 JPY per month. Kenta decided, "Let's start with a manageable 10,000 JPY per month for now." You can change your contribution amount at annual milestones, and you can also pause contributions if your household budget becomes tight.
Step 5: Select Investment Products Choose the products you wish to purchase from a lineup of 40 options. Kenta selected the "eMAXIS Slim All-World Equity (All-Country)" fund he had been eyeing for some time.
Step 6: Make Monthly Contributions and Continue Investing With this, automatic monthly investments begin, launching your long-term investment strategy. If you want to receive point rewards, remember to register your entry every month.
When all procedures were complete, Kenta felt a weight lift off his shoulders, thinking, "It was much easier than I expected." More importantly, his "vague anxiety about retirement" had transformed into "concrete savings for the future," marking a significant shift in his mindset.
Start by opening a free account and beginning at your own pace with a small amount. This small first step leads to peace of mind in the future.
So, Who Is Matsui Securities iDeCo Best For?—Kenta's Conclusion
After reviewing all the information, Kenta reached a clear conclusion. He confidently states that Matsui Securities iDeCo is ideally suited for the following types of investors:
- Those who want to accumulate popular index funds, such as the eMAXIS Slim series, at low costs
- Those seeking long-term investment growth while also benefiting from point rewards
- Those looking for an online broker with reliable phone support when issues arise
The fact that there are no account management fees, combined with the ability to invest in the proven and trusted "eMAXIS Slim All-World Equity (All-Country)," represents the two biggest reasons to choose Matsui Securities.
