I Keep Getting Within a Hair of ¥60M ($400K) — and Keep Getting Knocked Back to $387K

I get within a hair of ¥60M — and never quite cross it

A few weeks ago I opened my brokerage app like I do every morning, and the total read in the high ¥59 millions. Almost $400K. Almost.

¥60M is a number I’d had in the back of my head ever since I crossed ¥50M. And there it was, close enough to touch.

A few days later I opened the app again. ¥58M.

Maybe the yen firmed up. Maybe the market pulled back a little. Probably both, a little of each. Either way, the “almost ¥60M” had quietly slipped away in about three days.

These days I float somewhere between ¥58M and ¥59M. Up a bit, down a bit, never quite punching through the ¥60M wall.

The market is at an all-time high. So why am I stuck below the line?

Here’s the part that makes no sense on paper.

In June 2026, the Nikkei broke ¥68,000 for the first time ever. Foreign money keeps pouring into Japanese stocks, AI and semiconductors are dragging everything up, and the headlines read like a permanent party. In a market like this, you’d think my account would be printing new highs every week.

Instead it keeps bouncing off ¥60M and falling back.

The reason is boring once you see it. Most of my portfolio sits in dollar-denominated index mutual funds, so I eat both the stock move and the currency move. Stocks rise but the yen strengthens, and they cancel out. Or the opposite. I get close to ¥60M when those two things line up — then the moment one flips, I get shoved straight back.

It’s not an arrival. My fingertips brush it, and it’s gone.

If you’re not in Japan, this is the weird tax of investing from here: a Japanese salaryman holding U.S. stocks is running a leveraged bet on the dollar whether he wants to or not. My “wall” is partly a currency wall.

The bigger the portfolio, the heavier 1% gets

This is the thing I feel most these days.

When your portfolio hits ¥50M, ¥60M, the daily dollar moves get big. A 1% move is roughly ¥600K — about $4,000. On a day when the market really runs, the thing swings ¥1M ($6,700) up or down.

A million yen. That’s about six weeks of my household’s take-home pay. And it moves around on a Tuesday afternoon while I’m building a sales deck at the office, doing absolutely nothing.

Honestly, my gut didn’t keep up with the number of zeros at first. A few years back, when I was sitting around ¥20M, a 1% move was ¥200K. Same 1%, but when the absolute number triples, the view out the window is completely different.

And here’s the part that matters. The bigger you get, the more a round-number milestone like ¥60M stops being a place you can stand on. If the thing moves ¥1M in a day, then climbing to the high ¥59Ms on Monday and sliding to ¥58M on Tuesday is, statistically, a rounding error.

It’s less that the wall is hard, and more that the ground I’m standing on shakes by a million yen every day.

I didn’t change a single thing

So when I got within a hair of ¥60M, what did I do? Nothing.

“Maybe trim a little here” never crossed my mind. Not once. I haven’t sold a share of my index funds since 2018, and that’s one of the few things I’ve genuinely gotten right. If I ever sell, I sell all of it. And that’s not now. Brushing ¥60M for a day is not a reason to touch the portfolio.

Same when it fell back to ¥58M. I didn’t think “it dropped, let me buy more,” and I didn’t think “this is scary, let me cut.” ¥370K a month (~$2,470), same day every month, fully automated. That’s it.

Cash sits at about 20% right now. The rest is invested. There’s a voice in me that says you’ve got more now, you can afford to be aggressive. I ignore it.

The reason is a little embarrassing. I’m a coward by default.

Even with ¥60M in sight, I’ve decided not to make some big two-income push to break through. Growing it by attacking has never suited me as well as keeping it by being boring. Eight years in, that’s the one thing I know for sure.

The math says 5–6 months. But that’s not the real problem

Here’s where I do the thing I always do and reach for a spreadsheet. Yes, I track this in Excel. My wife thinks it’s a bit much.

I’m at ¥58M. ¥2M to go. ¥370K a month. If the market goes perfectly flat, ¥2M ÷ ¥370K lands around 5–6 months. ¥60M by year-end, on paper.

Except that math barely means anything, because markets are never “perfectly flat.” I ran three rough scenarios — same ¥58M starting point, same ¥370K monthly:

• Flat market: contributions alone get me there in 5–6 months.
• Up ~5% a year: gains plus contributions, probably more like 4 months.
• Down ~5% a year: I pour in ¥2M and the stock drop eats it, so I could still be at ¥59M half a year from now.

Lining those three up made me laugh a little. In every single scenario, the thing I actually do is identical: contribute ¥370K a month. The only lever I control is how much I put in. So I’d rather build a plan that doesn’t depend on guessing the market than try to time it.

By the way, I basically spend my whole paycheck every month. Pay the bills, send ¥370K to the funds, and land near zero. An aggressive household budget, I’ll admit. But it’s run like this for years.

At ¥50M I thought about growing it. Now I think about not losing it

Writing this, I noticed the ratio in my head has shifted.

Back around ¥50M, I spent more time thinking about how to grow it. Now I clearly spend more time thinking about how not to lose it.

On paper this is backwards. The more you have, the more cushion you’ve got, the more risk you can take. Textbook says the richer guy attacks more.

In reality it was the exact opposite. The more it grew, the more defensive I got. When you watch ¥1M disappear in a day enough times, the fear of losing slowly outgrows the fun of gaining.

I think it’s really the daily dollar move pulling on me, not the balance itself. At ¥20M a 1% wobble was ¥200K and I could shrug it off. That same 1% is ¥600K now. The urge to protect comes less from being richer and more from the swings getting wider.

So in my head, “being aggressive” has collapsed into one single thing: keep cash around 20% and don’t touch it. If I attack, I attack by contributing more — not by adding leverage or swinging for a home run.

Is this the right posture? Honestly, no idea. I’m probably leaving returns on the table by not pressing. But not at the price of my sleep.

¥60M isn’t a trigger. It’s just a number I stare at

After writing all this, one thing is clear to me.

¥60M isn’t a switch that makes me do anything. I don’t take profit when I reach it. I don’t ramp contributions when I miss it. It’s purely a mental marker — something to feel good or bad about during the morning app check.

Nothing more, nothing less.

And by the time I can actually stay above ¥60M, I’ll probably be staring at ¥70M. Milestones, it turns out, run away the moment you get close. (The honest, can’t-say-this-at-work version of how that feels, I put on my Japanese blog’s companion notes.)

Today I’ll do the same thing I always do. Open the app on contribution day, confirm “yep, bought again this month,” close it. Stuck at the wall or not, that part hasn’t changed in eight years.
