Unemployed Son Blows Up at Mother Who Torched ¥6 Million on Kioxia Stock

From our other sites

The story

The thread’s original poster (OP) is an unemployed only child. His mother, acting on a recommendation from the brokerage Toyo Securities, poured nearly all of her assets into Kioxia stock, and the portfolio’s value has sunk from an initial ¥35 million to ¥28 million. Despite having been badly burned by Toshiba stock in the past, the mother is again refusing to sell. The OP pleaded that “if you die, the inheritance shrinks and that’s a problem for me,” which touched off an argument with his mother — according to a post on 5ch’s “Nandemo Jikkyo G” board. Commenters were split: some dismissed the story as “usomatsu” (slang for an obviously made-up post) given how precisely the OP knew his mother’s finances and how unusual it would be for an amateur to dump everything into one stock, while others sympathized.

Mom: "It's not a loss unless you sell."
Me: "If you die, that's ¥6 million gone — do you have any idea how much trouble that causes me? Stop investing right now."

Why do you think you're entitled to your parents' money anyway?

Re: #5
Because I'm an only child
10AnonymousNov 5, 2026 14:37
I'm genuinely scared right now
I figured even if my parents died there'd still be ¥35 million
but it's already dropped to ¥28 million

Re: #10
That's an amount you could make back in 2 years if you just got a job
116AnonymousNov 5, 2026 15:16
Re: #10
It'll probably be down even more tomorrow
34AnonymousNov 5, 2026 14:42
lol he thinks exactly like me, I'm also a never-sell kind of guy
39AnonymousNov 5, 2026 14:43
Re: #34
Please, I begged her, just sell it and put it in savings
I screamed that I need the money for my certification studies
but she won't sell
37AnonymousNov 5, 2026 14:42
Even at a loss, if she sells now there's still money left over for OP to inherit, right?
41AnonymousNov 5, 2026 14:44
Re: #37
She's trading with cash, so there's no margin loss to worry about


Apparently she bought Toshiba stock ages ago, it became worthless, and she sold
Now she looks at Toshiba's current stock price and sees it's gone back up
and she can't let that go, so she brings it up every single time
47AnonymousNov 5, 2026 14:45
This thread's probably fake, but honestly, I don't even know how much money my own parents have
49AnonymousNov 5, 2026 14:46
Re: #47
I'm telling you, it's true
48AnonymousNov 5, 2026 14:46
I'm studying to become a US CPA
but the jobs are basically only in Tokyo
which means I'd have to rent an apartment there


Actually, even if I get certified, I'm not the type who can hold down a job
How am I even supposed to live from here on out
I'm currently in a house out in the countryside that's worth basically nothing

Oh, so you're the 'one certification will turn my whole life around' type of NEET, huh 💥👋

Re: #41
Bad wording on my part, but even with an unrealized loss, if she sells the actual shares there's still money left over, right?
55AnonymousNov 5, 2026 14:48
Re: #54
That's exactly the point — that leftover money is about to become a ¥7 million loss, that's why I'm pissed
59AnonymousNov 5, 2026 14:49
The son being unemployed is already the bigger disaster here, don't worry about the stock
61AnonymousNov 5, 2026 14:50
Re: #59
My family's all highly educated and my dad's dead
but they're still pinning their hopes on me, it's hilarious
I'm basically like Kioxia stock
still being told 'it'll go up eventually'
68AnonymousNov 5, 2026 14:52
Rough that lying is the only way you can get people to pay attention to you
72AnonymousNov 5, 2026 14:53
Re: #68
It's all true though
77AnonymousNov 5, 2026 14:54
If she'd just steadily averaged down (buying more as the price fell) instead of going all in, wouldn't she have avoided losing the full ¥6 million? 🤔
79AnonymousNov 5, 2026 14:54
Re: #77
She already dumped almost the entire amount in at once, so there's nothing left to average down with
78AnonymousNov 5, 2026 14:54
A mother who's been betrayed before, now betrayed by her own son too — genuinely sad
There are things more important than money, you know
81AnonymousNov 5, 2026 14:55
Re: #78
No, this time she's the one betrayed by Kioxia
80AnonymousNov 5, 2026 14:54
OP should just win his mom's losses back with high-leverage forex trading
82AnonymousNov 5, 2026 14:55
Re: #80
I've only got ¥2 million myself
88AnonymousNov 5, 2026 14:56
Show us some kind of proof that this is actually real
Right now you're just getting tagged as delusional, can't blame people
91AnonymousNov 5, 2026 14:58
Re: #88
No, it's true

Just reply assuming it's true
I'm using this for reference
93AnonymousNov 5, 2026 15:00
No way an amateur dumps their entire portfolio into Kioxia — this is definitely usomatsu (obviously fake)
94AnonymousNov 5, 2026 15:01
Re: #93
She was recommended it by Toyo Securities
106AnonymousNov 5, 2026 15:12
68 years old and still living a money-grubbing life, huh
108AnonymousNov 5, 2026 15:13
Re: #106
The money she's doing all this with is what my dad earned before he died 3 years ago
I gave her hell about that, nagging her over and over
117AnonymousNov 5, 2026 15:17
Re: #108
You should've said something before it blew up into a huge deal
Some of this is on you too
107AnonymousNov 5, 2026 15:13
OP's backstory is weak
That's not going to carry this thread to the finish
My 'college student' version would've been better
111AnonymousNov 5, 2026 15:14
Re: #107
No, it's not a 'backstory'

NandG (the "Nandemo Jikkyo" board) is full of liars
so lame replies like 'it's just a bit' or 'it's a made-up setup' really stand out
Just because you're a liar doesn't mean you get to call everyone else one, jackass

Background and Key Points of This Story

Kioxia is a major NAND flash memory maker that listed on the Tokyo Stock Exchange Prime market in December 2023, and the semiconductor memory market has seen heavy price swings amid AI-driven demand. What drew skepticism in the thread was that an individual investor had concentrated the bulk of her assets into a single stock recommended by her brokerage — the opposite of basic portfolio diversification. The OP’s repeated argument that “if my parents’ assets shrink, I’m the one who suffers” also split opinion, with some criticizing him for building his life around a future inheritance, and others arguing that concern over the mother’s investment judgment should be weighed separately. Even factoring in her past loss on Toshiba stock, the post doesn’t make clear why the mother is refusing to sell this time, and the conflict appears to stem at least partly from an information gap between mother and son.
