"Will my retirement funds be enough the way things are now…"
Meet Makoto Tanaka, a 35-year-old office worker at an IT company in Tokyo. With an annual income of ¥6 million and living with his wife and one child, he feels a vague sense of anxiety about his future pension every day. After a colleague told him, "With iDeCo, you can build assets while saving on taxes," he became interested in Matsui Securities' iDeCo. However, he is overwhelmed by the amount of information he needs to compare, such as fees, the number of products, and support systems. Like Tanaka, many people want to start preparing for retirement but struggle with taking that first step.
Conclusion: Matsui Securities' iDeCo stands out for its excellent balance of cost and support, featuring zero account management fees, a strong lineup of eMAXIS Slim funds, up to 1% point rewards, and 365-day phone support. It is especially recommended for beginners looking to start long-term investing at low cost and for those who value robust support.
How to Solve Retirement Anxiety? How Tanaka Found His Way to iDeCo

Tanaka's anxiety about "retirement money" is far from unique. With growing concerns that public pensions alone may not be enough to cover living expenses, the importance of self-directed asset building has been increasing year by year. Tanaka had almost no investment experience and, unsure which financial institution to use to start an iDeCo, simply watched the time pass by.
iDeCo (Individual-type Defined Contribution Pension) is a private pension system where you invest your monthly contributions in investment trusts of your choice and receive benefits from age 60 onward. Its biggest appeal is the tax-saving effect, where the full amount of your contributions is deductible from taxable income. For example, if a salaried worker earning 6 million yen per year contributes 20,000 yen monthly, it is estimated that their income and residence taxes would be reduced by approximately 83,000 yen annually. Since investment gains are also reinvested tax-free, it can be considered a system well-suited for long-term asset building.
What Tanaka heard from a colleague — "Matsui Securities' iDeCo has low fees, a wide selection of eMAXIS Slim funds, and you can also earn points" — became the first push that got him moving.
Is XM's iDeCo Really Cheap? A Thorough Comparison with Other Brokers
When choosing an iDeCo, fees are a critical factor that directly impacts long-term returns. Matsui Securities' iDeCo offers an unconditional ¥0 administration fee. The monthly account management fee is ¥171, placing it at a low-cost level (a clear monthly cost among major online brokerages). The initial ¥2,829 fee upon enrollment is charged by the National Pension Fund Association and is common across all financial institutions.
Tanaka checked whether the "low fees" he heard from a colleague were true by comparing major online brokerages.
| Item | Matsui Securities | SBI Securities | Rakuten Securities | Monex Securities |
|---|---|---|---|---|
| Administration Fee | ¥0 (Free) | ¥0 (Free) | ¥0 (Free) | ¥0 (Free) |
| Monthly Account Management Fee | ¥171 | — | — | — |

| Number of eMAXIS Slim Products | 13 | 8 | 0 | 6 |
| Points Rewards | Up to 1% | None | — | None |
| Support System | 365-day phone support | — | — | — |
While all brokers offer free administration fees, Matsui Securities stands out with a clear ¥171 monthly account management fee. Other brokers have different fee structures, making direct comparison difficult, but Matsui Securities' cost transparency is notable. You can check the latest fee structure on the official website.
An Honest Look at the Pros and Cons of Matsui Securities iDeCo

Since iDeCo invests in mutual funds, there is no principal guarantee, and losses are possible. However, long-term periodic investments help diversify risk, and combined with tax benefits, it is an effective tool for building retirement funds. Tanaka understood that most of the disadvantages were either common to all iDeCo plans or could be mitigated through investment choices, so he decided to move forward with a positive outlook. Additionally, Matsui Securities offers free account opening and demo trading, providing a risk-free environment to get started.

Clearing Up Questions About Matsui Securities iDeCo
The last thing Mr. Tanaka was concerned about were a few lingering questions. Let's clear those up here.
Is the sales pitch pushy? Matsui Securities is an online broker, so there's no aggressive in-person solicitation. Phone support is mainly for handling inquiries, and user reviews praise it as "easy to reach" and "responsive."
Are the fees actually high? The administrative management fee is ¥0, and the monthly account management fee is ¥171. This clear, low-cost structure (a transparent monthly cost among major online brokers) keeps expenses minimal. The ¥2,829 enrollment fee is standard across all financial institutions, so Matsui Securities isn't any more expensive.
Is the limited number of products a concern?

Notably, it offers 13 funds from the popular, low-cost eMAXIS Slim series—a strength that surpasses competitors.
Are the point rebate conditions a hassle? You can earn up to 1% points based on your investment trust balance, but you need to opt in monthly. The enrollment process itself is simple and takes just a few clicks. Given the high rebate rate, it's a worthwhile benefit for the minimal effort.
Is support only available on weekdays inconvenient? Phone support hours are weekdays from 8:30 AM to 5:00 PM. However, user reviews frequently mention that "calls get through quickly even during weekday daytime hours," indicating a system that handles urgent inquiries well.
The biggest appeal of Matsui Securities' iDeCo is that it keeps costs low while providing reliable support when you need it. Opening a free account is a low-risk, solid first step toward investing in your future self.
Investments are not principal-guaranteed, and losses may occur depending on performance. While iDeCo's long-term accumulation approach can help diversify risk, results will vary based on product selection and market conditions. Before applying, please carefully consider your investment strategy and risk tolerance.
