Yen Hits 140s Against the Dollar—5ch Users Can’t Agree on What Counts as “Fair”

From our other sites

The story

On September 9, 2026, after the yen slid into the 140s against the dollar in foreign exchange trading, a breaking-news thread went up on 5ch’s “Nandemo Jikkyo G” (Live Commentary) board. Posters piled in with wildly opposing wishes—”still not weak enough, let it break past 120,” “hurry up and bring it back to 100–110″—and opinions on the “right” exchange rate ended up scattered anywhere from the 100s to the 300s. The thread laid bare the gap between investors welcoming the weak yen and everyday people who hate rising prices, with talk of familiar price hikes—like Bireley’s soft drinks going up—mixed into the debate.

is right around the corner

There's no way there's still some slowpoke out there who hasn't cashed in their NISA (tax-free investment account), right?
This is only the opening act of rate hikes—keep holding and you're in for a world of pain.

Whether it's climbing or falling, it moves way too fast.
16AnonymousSep 9, 2026 13:40
Let's keep it simple: 1 dollar = 1 yen.
19AnonymousSep 9, 2026 13:41
Companies: "The yen's weak, so prices are going up… can't be helped 😥"
Companies when the yen strengthens: "Oh really? 🙄"
21AnonymousSep 9, 2026 13:42
Still way too weak
Keep going till we break through 120.
23AnonymousSep 9, 2026 13:42
Hurry up and get it back to 100~110 yen already 😠
27AnonymousSep 9, 2026 13:43
A strong yen has zero upside
because prices that got hiked during the weak-yen period never come back down.
So a weak yen's better—it's nothing but upside.
29AnonymousSep 9, 2026 13:45
Wouldn't it only be fair if it were 1 dollar = 1 yen?
Why does America get to just act like their country's automatically the strongest?
49AnonymousSep 9, 2026 14:06
Re: #29
Should we just send it back to 360, then?
103AnonymousSep 9, 2026 14:53
Re: #29
If it's 1 yen, that'd make it 1 cent.

[Sad news] Bireley's juice price breaks through the ceiling


The weak yen is hell.

Re: #33
Only 10% fruit juice and it costs this much? That's overkill.
46AnonymousSep 9, 2026 14:05
Re: #33
It's not a daily necessity, so it can be pricey, no big deal.
75AnonymousSep 9, 2026 14:32
Re: #33
It tastes like garbage—who's even buying this?
Wouldn't touch it unless I were stranded in the middle of a desert.
36AnonymousSep 9, 2026 13:53
You guys have nothing going on but Monster Strike anyway, so who cares 🤣

I play Uma Musume too, don't underestimate me 😤😤😤
41AnonymousSep 9, 2026 13:57
120 yen, please.
If that's not possible, 130.
44AnonymousSep 9, 2026 14:03
Re: #41
This feels like haggling over a price on Mercari (Japan's flea-market resale app).
47AnonymousSep 9, 2026 14:05
I'm heading overseas soon—if I do some "kankin," does the rate apply right away? (joking pun: 監禁 "locking someone up" sounds identical to 換金 "cashing out currency")
53AnonymousSep 9, 2026 14:09
Re: #47
Never locked anyone up before, so I wouldn't know.
57AnonymousSep 9, 2026 14:11
Re: #47
Handle it properly yourself.
Take it to an exchange counter and they'll often shift the rate by a few yen and call it a "fee"—
the more you exchange, the more you get ripped off.
59AnonymousSep 9, 2026 14:15
Apparently at 120 yen, Japan comfortably overtakes Germany's GDP again.
Guess that's about the right level, then.
61AnonymousSep 9, 2026 14:16
Re: #59
If it all comes down to the exchange rate,
that just means it's a meaningless indicator.
68AnonymousSep 9, 2026 14:22
If only it could get back to around 130 like it was back then.
71AnonymousSep 9, 2026 14:29
I think somewhere between 120 and 135 is fair
even though my S&P 500 holdings would take a temporary hit.
80AnonymousSep 9, 2026 14:35
Re: #71
If anything, that's a good deal—you get to buy way more.
72AnonymousSep 9, 2026 14:31
Think about the country's actual strength and it's obvious this is temporary
a strong yen won't last.
77AnonymousSep 9, 2026 14:33
Re: #72
Given the country's actual strength, the yen's too weak to begin with.
76AnonymousSep 9, 2026 14:33
180 to 200 yen is probably about right.
82AnonymousSep 9, 2026 14:36
Re: #76
Shinzo Abe: "Once it hits 300 yen, Japan's economy will be revived."
79AnonymousSep 9, 2026 14:35
There's no way some dummy out there is infinitely averaging down on a long dollar-yen position, right?
84AnonymousSep 9, 2026 14:36
Re: #79
Either infinite averaging-down or a double-or-nothing revenge trade.
85AnonymousSep 9, 2026 14:37
Re: #79
A "short sleeper." (pun: also reads as someone stuck holding a losing short position)
107AnonymousSep 9, 2026 14:55
Someone who actually knows this stuff, explain it to me.
At the end of the day, is the weak yen actually a bad thing? Companies exporting overseas sell more and the economy does better because of it, right?
I don't really get it.

Don't worry about it.

Background and Key Points of This Debate

This thread sprang up after the yen slid into the 140s against the dollar, with 5ch users each weighing in on where the “right” exchange rate should actually sit. The fact that opinions scattered anywhere from the 100–110 range to 180–300 is itself evidence that there’s no clear “correct answer” for either a weak or a strong yen. Exporters and people holding stocks or other investment assets tend to welcome a weak yen, while everyday consumers who feel the pinch from pricier imports, overseas travel, and daily goods tend to want a stronger one. One comment in the thread—that prices raised during a weak-yen period don’t come back down once the yen strengthens—points to something that’s easy to overlook when thinking about the relationship between exchange rates and prices, and shows that the simple “weak yen bad, strong yen good” framing doesn’t fully capture reality. As a side note, the exchange about “360 yen” was a joke referencing the fixed-rate era that lasted until 1971—worth noting that Japan operates under a completely different, floating-rate system today.
