NISA Fuels an Investment Boom Among Japan’s Youth — and a New Breed of “NISA-Poor”: 5ch Weighs In on “Everybody’s Mr. Passive Income”

From our other sites

The story

Fueled by the spread of NISA (Japan’s tax-free small-investment program) and a rising stock market, interest in personal investing has surged among young people in Japan. While “FIRE” — building enough wealth to retire early — is drawing attention, the term “NISA-poor” has also emerged to describe people who cut back on daily life just to keep investing, prompting experts to warn of the risks of getting too deeply invested. After the Yomiuri Shimbun profiled a woman who lives comfortably while making videos on the side, 5ch users split over whether investing is “gambling or solid asset-building” and whether FIRE is good for society. Some called long-term, dollar-cost-averaging investment “a gamble with great odds of winning,” while others took a cooler view, distinguishing between unrealized gains and locked-in profits and arguing that “most people actually end up losing in the end.”

Against a backdrop of NISA’s spread and a rising stock market, interest in personal investing is climbing, especially among younger people. Investment amounts through NISA have also surged, and the “FIRE” lifestyle — building up assets to retire early — is drawing attention. At the same time, some people are getting too deeply invested, giving rise to the term “NISA-poor,” and experts are warning that an excessive focus on investing carries real risk. (By Kotaro Hirose)

There's a life-insurance saleswoman who visits my workplace, and she says the younger the client, the more likely she is to sign them up for investment products instead of life insurance.

What's the deal with investment products from insurance companies anyway? Aren't the fees baked in like crazy?

Graduating from the proletariat — what's wrong with that?

Re: #22
Honestly, steady investing from a young age is the best way for an ordinary person with no special talent to escape the proletariat. Anyone can do it, and it's highly repeatable.

Full FIRE with kids on 50 million yen seems impossible even living out in the countryside, doesn't it? I'm single with 65 million yen and I'm still nervous about FIRE.

Re: #24
Yeah, with the 4% rule that's just not doable.
33AnonymousSep 3, 2026 15:50
Can you actually FIRE using NISA? Isn't it just pocket change in the end?

It's just a stepping stone.

You max out your NISA allowance, then move to a taxable account.

"She also makes sure to keep earning several hundred thousand yen a month from video streaming and the like."

That part is the real crazy thing here.

That's just… running a business from home, isn't it?

Ah, I see — so the video income is the main source, not investment returns.

Retiring before 40 with a wife and kids on just 50 million yen — bold move.

However you look at it, that's too early.

This is basically a "locust harvest" (slang for luring small retail investors into a pump, like locusts to a field). Everyone's convinced that the S&P 500, All-Country index funds ("Orukan"), whatever — hold it long enough and it'll go up, up, up. At some point it'll crash hard. If there's a two-year downturn, I wonder how many people could actually keep their nerve.

Forget two years — with NISA the investment horizon is more like 20 years.

20 years from now, the US might be in decline though.

Re: #84
Only God could predict that — same goes for exchange rates and stock prices.
97AnonymousSep 3, 2026 16:08
Re: #84
There are options — switching out of the US, or who knows if NISA itself will even still be around by then. Given the contribution caps, it's designed as a long-term thing, so even through economic crises the approach is basically to keep going on autopilot.

Re: #90
So it's gambling, then.

Re: #92
The world economy's upward trend hasn't broken since humanity began, so… yeah, it's a gamble, but one with ridiculously good odds of winning.

Re: #98
There's no such thing as a gamble where every single participant wins. Think about it rationally — an unprecedented correction is coming at some point.
106AnonymousSep 3, 2026 16:12
Re: #100
That's just wishful thinking on your part lol. Well, if you're convinced everyone's headed for huge losses, just leave them to it.
116AnonymousSep 3, 2026 16:16
Re: #106
Even if people say they've grown their assets with NISA, it's just unrealized gains until they actually cash out. Sure, some people cash out and win the game of Old Maid (i.e., don't end up holding the bag), but the only reason winners exist is because so many others lose and get stuck holding it. In other words, the majority end up losing in the end — which is just obvious, really.
119AnonymousSep 3, 2026 16:17
Re: #116
Nearly 40% is already cashed-out profit lol. Even if there's a crash, I can easily buy more.
124AnonymousSep 3, 2026 16:19
Re: #116
No idea about margin traders, but most people doing cash investing are probably winning.
120AnonymousSep 3, 2026 16:18
Why does everyone want to FIRE so badly? If more and more people start thinking 'a good life means not working,' national strength is going to decline. And once that happens, stock prices will stop rising too, so nobody will be able to FIRE anymore. FIRE should be for the small cream of the crop at the top — everyone below that still needs to work.
132AnonymousSep 3, 2026 16:21
Re: #120
If the cream of the crop can't or won't do work that actually contributes to society in the first place, that's a society in its death throes.
162AnonymousSep 3, 2026 16:30
Re: #120
People who think like this just don't understand capitalism, honestly. Switching from wage laborer to capitalist doesn't cause national strength to decline.

They've already started steering the yen stronger — you sure that's fine?
159AnonymousSep 3, 2026 16:29
Re: #154
And? Stock price gains far outpace currency swings anyway. Talk data, not vibes. You just resent people wealthy enough to invest, don't you lmao
169AnonymousSep 3, 2026 16:32
Re: #159
Honestly, the mentality and character it takes to try to be the one who cashes out first in this whole 'Old Maid' game of investing just strikes me as ugly.
171AnonymousSep 3, 2026 16:33
Genuine question, but isn't investing supposed to be done with money left over from everyday life? Why are people cutting back on living more than they need to?
177AnonymousSep 3, 2026 16:34
Re: #171
Because it's more efficient that way, obviously.
179AnonymousSep 3, 2026 16:36
Re: #171
If you can cut it, it was surplus to begin with.
193AnonymousSep 3, 2026 16:40
This might sound harsh, but if you want to keep up with inflation just to maintain your standard of living, wage income alone will never be enough. So it's only natural that young people, whose pay relative to their labor is low, turn to investing.

Starting young also means the compounding effect is huge.

Re: #193
Then again, new grads these days get paid well, so they've got real firepower to invest with too.

Background and Key Points of This Discussion

NISA was overhauled in 2024, expanding the tax-free holding limit to 18 million yen and making the investment framework permanent — a change that sits behind both the article and this thread, since it triggered a surge in account openings and contribution amounts among young people. FIRE is a concept that originated in the US, commonly using the “4% rule” — the idea that withdrawing 4% of assets annually shouldn’t meaningfully deplete the principal — as a rule of thumb; the thread itself raises the point that “the 4% rule makes it impossible,” and it’s easy to overlook how much the required asset amount varies depending on family situation and living standards. It’s also worth noting that “unrealized gains” and “realized profit” are different things — a rise in valuation during a long holding period doesn’t mean the gain is locked in. The thread’s central divide is between an optimistic view that sees regular investing as “the most reproducible way to build wealth” and a risk-focused view holding that “a major correction will eventually come” or “in the end, only the ones who sell out in time actually win” — both are commenters’ own market opinions, not something stated in the article itself.
