Individual Bonds Over NISA? 5ch Debates How the Risk-Averse Should Build Wealth

From our other sites

The story

The thread kicked off with a challenge to people who say “investing scares me because I might lose money”: why not just buy principal-guaranteed individual government bonds? Posters noted these bonds pay more interest than an ordinary savings account and won’t lose principal unless Japan itself goes broke — though others countered that the rate gap isn’t huge and the paperwork hassle barely pays off. As the talk rolled on, it expanded to cover regular investing in All-Country (“Orukan”) and S&P 500 index funds, bank time-deposit promotions, and how big an emergency fund should be, with the thread converging on the idea that bonds, savings, and stocks should be mixed according to one’s risk tolerance.

Unless Japan actually defaults, you get your money back — super low risk. And if Japan does default, the yen becomes worthless paper anyway, so it's basically a souped-up savings account.
Plus you get something like 5-6x the interest of most ordinary savings accounts.
The only real downside is you can't touch it for a year. It's genuinely a great deal, why isn't everyone buying these?

I guess it's a bit of a hassle for not much payoff. That's the downside.

If you put in a large sum, the difference really adds up though.
11AnonymousSep 28, 2026 11:14
Pretty much every self-employed person already maxes out the Small Enterprise Mutual Aid (a tax-advantaged retirement fund for the self-employed) — that's basically their investment right there.

Re: #11
But there are way more non-self-employed people out there.

Re: #9
I guess the logic is: people who can handle the hassle go for stocks that pay off bigger, and people who find it a hassle won't bother with bonds either if the gains are that small.

Re: #16
Hmm. Setting the second group aside, I'd still want to nudge the stock crowd from the first group into buying at least a little.
I'm in All-Country myself, and even though it'll probably outperform, I hold a solid chunk of bonds too just to keep my head straight during a crash.
Panic-selling would defeat the whole point.

Are banks getting nervous with everyone rushing into investing?
My mom, who just hit retirement age, brought home a flyer saying NISA's too confusing for her now so she wants a time deposit instead — about 1.9% on 3 million yen over 3 years, so a guaranteed +300,000 yen with zero risk of loss isn't bad at all.
Honestly she might out-earn me, and I only started NISA this year.

Re: #23
Bank time deposits have gotten better lately too, though sometimes that rate includes a promotional bonus.
26AnonymousSep 28, 2026 11:22
Re: #23
It's decent, but for something like a 3-year term, individual bonds actually beat a time deposit. Time deposits are better suited to 6-month or 1-year terms.
25AnonymousSep 28, 2026 11:22
Just goes to show most people out there aren't that into money.
27AnonymousSep 28, 2026 11:23
Re: #25
Really? Feels like talk about investing and saving has been on the rise though.
28AnonymousSep 28, 2026 11:23
Re: #24
Yeah, it included the promo bonus — seems the condition was opening a new account.
I did look into the bank first before giving the go-ahead, though.
A friend told me it'd pay off more if I borrowed that 3 million and built her a portfolio, but that scared me, so I had her go with the time deposit instead.
You never know how much longer your parents will be around, anyway.
33AnonymousSep 28, 2026 11:25
Re: #28
I think that's the right call. Even with a promo bonus tacked on, if the conditions line up it's still a good deal.
29AnonymousSep 28, 2026 11:24
This is my debut round.
Throwing in a few hundred thousand yen I made off semiconductor stocks.

Re: #29
Nice. Shore up your defenses too and build that grip strength (i.e., the nerve to hold through a downturn) 💪
34AnonymousSep 28, 2026 11:25
I'm a second-generation self-employed guy, but my freelancer friends are all "Mutual aid? What's that? Tax savings sound like too much hassle" types.
42AnonymousSep 28, 2026 11:28
Re: #34
Uh… are they rich, or just completely checked out?
35AnonymousSep 28, 2026 11:25
I think it's fine to take risks with NISA while you're still working — if you lose money, you can just keep working to earn it back.
Shifting into defensive assets is a conversation for after you retire.
43AnonymousSep 28, 2026 11:28
Re: #35
My risk tolerance is low, so I buy bonds too, for the grip strength. Of course I buy All-Country as well.
36AnonymousSep 28, 2026 11:25
Even at 5x an ordinary savings rate, that's just 5x of 0.1% — only 0.5%. All-Country gets you over 3%.
39AnonymousSep 28, 2026 11:27
Re: #36
Which bank pays 0.1%? My local regional bank's ordinary savings rate is 0.4%.
And right now you get around 1.9% on the 3-year bond and about 2.2% on the 5-year, if I remember right.
41AnonymousSep 28, 2026 11:27
Yeah, at this point buying these bonds is on the same level as buying Chinese stocks.
44AnonymousSep 28, 2026 11:28
Re: #41
Chinese stocks don't come with a principal guarantee though…
72AnonymousSep 28, 2026 11:42
Keeping your money in a bank carries its own risk too, and I don't mean deposit-insurance payout limits or anything like that.
73AnonymousSep 28, 2026 11:43
Re: #72
What kind of risk are we talking about? Seriously, tell me.
77AnonymousSep 28, 2026 11:44
Re: #72
Because inflation is expected to keep climbing over the long run.
74AnonymousSep 28, 2026 11:43
The thread title's one thing, but the All-Country/S&P true believers scare me too.

Life is long and there'll be times you need cash, yet they assume you can just keep contributing for 10+ years straight.
And not many people have the mental fortitude to keep buying in while watching their losses pile up during a downturn.
76AnonymousSep 28, 2026 11:44
Re: #74
This is seriously true. If you don't have that mental margin, better to raise your bond allocation and keep more in savings.
84AnonymousSep 28, 2026 11:47
Re: #74
Normally you wouldn't put your emergency fund, or tuition savings if you've got kids, into investments anyway.
You buy All-Country on the assumption that money's locked away for the long haul.
75AnonymousSep 28, 2026 11:44
The yen itself is actually the thing crashing hardest, when you think about it.
79AnonymousSep 28, 2026 11:45
Re: #75
Ordinary savings accounts are the real danger. Go with All-Country or bonds — or at minimum a time deposit with a decent rate.
81AnonymousSep 28, 2026 11:46
Re: #75
There's also the risk the US forces a stronger yen on us, so it's hard to say anything for certain.
98AnonymousSep 28, 2026 11:53
Re: #75
Buy low, sell high is the basic rule — so if not now while the yen is cheap, when?
82AnonymousSep 28, 2026 11:46
Honestly, point-farming ("poikatsu" — stacking cashback/reward points) is safer. 3% a month with zero risk.
85AnonymousSep 28, 2026 11:47
Re: #82
Well, if we're going there, a side hustle pays even better rates. This is specifically about ordinary asset management though.
87AnonymousSep 28, 2026 11:48
Re: #82
You should factor this in too — a floating-rate individual bond gets you 2%, and a Mizuho Rakuten Card gets you another 2%, so you can lock in 4% just from everyday spending.
92AnonymousSep 28, 2026 11:52
You're better off waiting a bit longer on bonds since the rate should climb further.
94AnonymousSep 28, 2026 11:52
Re: #92
True, but there's also a chance rates drop — low, but not zero — so I'll just buy in now while I can.
97AnonymousSep 28, 2026 11:53
Re: #92
That's exactly why it's the 10-year floating-rate bond.

Background and Key Points of This Discussion

Individual government bonds (such as the 10-year floating-rate type) are issued by the state, so they never lose principal value. Current market rates run around 1.9% for the 3-year bond and 2.2% for the 5-year, both well above the 0.1-0.4% typical of ordinary bank savings accounts. That said, they generally can’t be cashed in early for a full year, and the payoff is small unless you’re investing a substantial sum. NISA and All-Country (an all-country equity index fund), by contrast, carry no principal guarantee but open the door to long-term capital gains and tax-free allowances — which demands the mental fortitude to keep contributing even while prices are falling. The thread split over whether to build a portfolio around “principal-guaranteed but slow-growing bonds” or “stock investing that can grow but can also fall,” with many participants converging on the idea that combining both, weighted by age and the size of one’s emergency fund, is the sensible approach. The conversation also touched on how to think about dollar-denominated assets amid the weakening yen — a reminder that this isn’t a topic with one simple right answer.
