Client: Male (30), company employee, with wife and a baby

The consultation:

His job pays reasonably well but demands a lot. He’d like to retire around 50, but has no real sense of how much he’d need to save. Last week he asked an AI, and it gave him a figure: ¥120 million. That number is what brought him in.

Where did ¥120 million come from?

When we looked at it together, the logic behind the number was this: invest at a 4% annual return, and the ¥4.8 million in yearly interest could support a couple without touching the principal. A 4% return from index funds is realistic, so the math isn’t wrong.

But he hasn’t opened a NISA account yet. “I’ve been meaning to, just haven’t gotten around to it.” That’s a common situation.

The first thing worth saying: ¥100 million is achievable for an ordinary dual-income couple. It just tends to happen around 60 or 65. Retiring fully at 50 is a different plan, and requires a different approach.

Before the numbers, a different question

Before building a money plan, I always start with a worksheet: what do you actually want early retirement for?

He listed three things:

• More time with family
• Time to pursue a research interest
• Travel

I told him: you can do all three without retiring.

“There’s just no time for that right now,” he said.

That’s really not a savings problem. It’s a question of how he works, what he prioritizes, and how he manages his time.

Some things only happen now

Working overtime and weekends to save for early retirement, while family time keeps shrinking — that’s working against the goal.

By the time the money is saved and retirement arrives in 15 years, the kids will likely be grown and gone. The years with young children at home don’t come back later.

The same goes for the research he wants to do. Even two hours a week adds up to over 1,500 hours across 15 years. Put it off, and the motivation may fade — or someone else may get there first.

Travel is similar. Traveling with young children has its own challenges, but also its own rewards. I took my own child to the US at two months old. Domestic trips every year, international ones every couple of years. Travel gets harder to enjoy the same way as you get older — I used to windsurf and scuba dive, and I don’t have much interest in either anymore. Curiosity and range narrow gradually with age.

The things you want to do don’t need to wait for retirement.

No one is guaranteed to reach retirement age

There’s also no guarantee that you, or your family, will be alive by the time retirement arrives. I’ve seen people pass away right before or just after retiring, without having done the things they’d been saving for.

Last month, a young friend of mine died suddenly at 30 — the same age as this client.

That’s the basis of how I approach planning: build a plan you won’t regret whether you die next year or live to 120.

Rather than chasing FIRE, it’s worth focusing on the next ten years. Setting aside 15% of take-home income through your 30s is generally enough to buy a home, raise children, and prepare for retirement without strain. For a dual-income household, retiring in your 50s — well before 65 — is a realistic possibility.

If you enjoy your work, you don’t want to quit it

One more point, and it runs a bit against the grain: if you genuinely enjoy your work, the idea of quitting usually doesn’t come up.

I know several people in their 80s still working — doctors, lawyers, a pastor, an artist, a chef. They want to keep working as long as they’re able. The same is true of the couple who run the tonkatsu restaurant I go to, or people in farming and fishing. Work itself isn’t the problem.

If the job feels unbearable, it’s often not the work itself but the way it’s structured — long hours, a long commute, no time off, too much stress. No job is free of stress, but it’s easier to handle when there’s something meaningful in it.

Rather than assuming you have to grin and bear it as an employee, it’s worth asking whether the current environment can be changed. If it can’t, changing jobs is an option too — and the deciding factor shouldn’t be salary alone. A role that’s meaningful and leaves room for family life, even at 10–20% less pay, often adds up to more in the end.

Key takeaways

• Treat an AI-generated “amount you need” figure as one estimate, not a verdict — check the assumptions behind it
• Many of the things people want from early retirement can be pursued now, without retiring
• Saving 15% of take-home income through your 30s makes ¥100 million a realistic target for a dual-income couple
• If the job itself is the problem, changing how you work — or where you work — is an option worth considering
• Aim less for FIRE and more for staying engaged in work you don’t need to escape 

If you’re carrying a vague sense of “I don’t know if I’m saving enough” or “is this really the right path,” you don’t have to sort it out alone. We can start not just from the numbers, but from what actually matters to you.
