iDeco in Japan: How to Set It Up and Grow Your Pension Savings
Thinking about your financial future in a foreign country can be overwhelming. But thankfully, there's a smart solution designed just for that: iDeco, Japan’s tax-friendly savings and pension plan. Whether you’re here on a working visa or planning to settle long-term, getting familiar with iDeco can help level up your savings and investment game.
Designed to help residents in Japan build their retirement fund with tax perks, iDeco offers an accessible way to take control of your future. In this guide, we’ll walk you through what iDeco is, how to open an account, popular providers, and what foreigners should know before signing up.
What is iDeco?
iDeco (short for "individual-type defined contribution pension plan") is a government-supported savings and investment program aimed at helping residents in Japan prepare for retirement.
Here’s the simplified version of how it works:
- You contribute monthly (between ¥5,000 and ¥62,000, depending on your job type).
- You choose how the money is invested, whether in mutual funds, fixed deposits, or a mix.
- Your account grows tax-free while you save.
- Once you reach retirement age (between 60 and 75), you can withdraw your funds, either as a lump sum or in instalments.
Since you choose how and where your money is invested, iDeco is more than a pension plan - it's a flexible tool for long-term savings and investment growth.
Why Should You Consider iDeco?
If you’re serious about saving for the future, iDeco is one of the best-kept secrets in Japan’s financial world. Here’s why:
- Income tax deductions: Contributions lower your taxable income.
- Tax-free growth: Your gains and dividends aren’t taxed while they grow.
- Low-cost options: You can choose from affordable index funds or safer options.
- You’re in the driver’s seat: Unlike corporate pensions, you decide where your money goes.
Keep in mind: You can’t withdraw the money until at least age 60, so only contribute what you can afford to set aside long-term.
Can Foreigners Join iDeco?
You don’t have to be a Japanese citizen to join iDeco! But there are a few boxes you’ll need to tick:
- Be between 20 and 65 years old
- Be enrolled in Japan’s public pension system (Kokumin Nenkin or Employees’ Pension)
- Have a Japanese address.
- Not receiving certain types of corporate pension benefits already (double-check this based on your employment type).
Even if you’re planning to return to your home country eventually, contributing to iDeco while you're here can help reduce your taxes and grow your investments during your time abroad.
