The x25 Rule – How to Save for Retirement in Japan

how to retire in japan using the 25x rule

Retirement, envisioned as a serene phase of life, demands meticulous planning, disciplined saving, and prudent investment. For foreign residents in Japan, saving for the unique expenses of an international lifestyle becomes even more paramount – especially in light of Japan’s ever-weakening pension system. But how can you ensure that the amount you are saving now will support you and your loved ones through your retirement years in Japan? That is where the x25 rule comes in to help.

Why Foreign Residents of Japan Need To Save For Retirement

The 25x Rule for Retirement in JapanWhile the promise of a pension can be a comforting thought, the reality is that most pension systems around the world do not provide enough for retirees to live on. The Japanese pension system, in particular, is getting weaker every year due to the growing elderly population and diminishing workforce

With a rapidly aging population and a declining birth rate, the proportion of retirees to working-age individuals is widening. This demographic shift places immense stress on the nation’s pension fund, which was initially structured for a younger population. With more retirees drawing from the pension fund and fewer young workers contributing, the system is becoming increasingly unsustainable.

To counteract the pressures on the pension system, the Japanese government has resorted to measures like raising the retirement age and cutting back on benefits. These steps directly impact the financial security of those relying on a government pension. Given the challenges the system faces, foreign residents must be proactive, seek alternatives, and chart a secure retirement path for themselves.

What is the x25 Rule for Retirement Saving?

What is the x25 Rule for Retirement Saving?
The x25 (or 25x) Rule is a fairly straightforward strategy by which you can calculate the amount of savings you need to amass by the time you retire in Japan and start drawing down your account to fund your lifestyle after your career finishes. The theory finds its roots in the 4% Rule, which refers to the assumption that in your first year of retirement, you should be able to safely withdraw 4% of your retirement portfolio. 

Annual withdrawals thereafter would be adjusted to accommodate inflation. In theory, by the time you retire, your savings should be enough to allow you to make these adjusted withdrawals year-by-year for 30 years without exhausting your retirement funds. 

The 4% value represents the amount you need to live comfortably in retirement for one year. If you multiply that amount by 25, you arrive at 100% of the total amount you need to live comfortably in retirement for a full 30 years. 

How To Use The x25 Rule to Calculate Your Retirement Savings Needs in Japan

If all of that mathematical theory has you confused, don’t worry. Applying the x25 Rule in practice is fairly simple. First, you’ll need to come up with an estimated budget for a single year of your retirement in Japan (or wherever you plan to live). An experienced financial adviser can help you do this. Here are some of the steps you can take with their assistance to ensure an accurate estimation.

  • 1.  Consider Your Desired Post-Retirement Lifestyle:
    What kind of life do you imagine living in retirement? Perhaps you see yourself maintaining your current lifestyle and simply enjoying more free time. Or perhaps you’re aiming for something more luxurious. Accurately estimating your post-retirement living expenses requires creating a detailed projection of how your retired life will look. Some questions to ask yourself include:
    • Planning for Retirement in Japan for Foreign People
    • -Housing: Will you continue to live in Japan during retirement? Do you see yourself living in a bustling city like Tokyo, or would you prefer a peaceful rural setting? The cost of housing can vary greatly between locations, and this will have a significant impact on your retirement budget.
    • -Utilities & Daily Expenses: Will your electricity, gas, water, groceries, and transportation costs remain the same after retirement, or will you be moving to a location that could incur greater costs to take into consideration?
    • -Healthcare: Japan has an excellent healthcare system, but there are many expenses associated with aging that may not be covered under social insurance. Do you already have critical illness insurance to supplement your national insurance, or will you need to budget in a higher emergency fund in case of a critical health event?
    • -Leisure Activities: Will you be traveling internationally frequently to visit family? Do you see yourself dining out often, participating in cultural festivals, or taking up new hobbies that might add to your annual expenses?

  • 2. Calculate Your Annual Post-Retirement Expenses
    After establishing a detailed vision of your post-retirement lifestyle, it’s time to start calculating. If you aren’t expecting any significant changes, you can begin by analyzing how much you spend in a year currently and then adjust accordingly. However, if you expect your post-retirement lifestyle to be very different from your current lifestyle – such as if you intend to move to another country – you can start from scratch. Either way, you’ll want to take into account all of the expenses associated with the lifestyle factors considered in step 1 to calculate a year’s worth of expenses.
  • 3. Factor In Estimated Post-Retirement Income
    Limitations To The x25 Rule
Once you have your estimated total for a year’s worth of expenses, you’ll subtract expected retirement income from other sources. These sources could include: 
    • -Any pension you might receive (either from Japan or your home country).
    • -Earnings from part-time jobs or passive income streams.
    • -Investment returns.
  • 4. Applying the x25 Rule
    Finally, multiply the yearly amount you’d need from savings by 25. This will give you a ballpark figure of the total savings required to sustain your envisioned lifestyle in Japan for your retirement years.

To put the x25 rule into proper context, here’s a working example:

Say your envisioned retirement budget is ¥6,600,000. You estimate other retirement income sources to come to ¥1,650,000. This means you’d need your savings to provide the remaining ¥4,950,000 for one year. By the x25 Rule, this translates to a total savings goal of ¥123,750,000 (¥4,950,000 multiplied by 25).

Limitations To The x25 Rule

The x25 Rule provides a great starting point for calculating your retirement savings needs. However, as with many financial principles, the x25 rule is based on averages and doesn’t account for individual circumstances. Furthermore, retirement savings alone do not constitute a full and sound retirement plan. As such, it’s important to seek guidance from an experienced professional. A qualified financial adviser can help you establish a robust retirement portfolio, including a detailed savings plan that is tailored to your individual needs.
