The story
A roughly ¥300 million monument called the “One Health Carbon Gate,” built in Chikugo City, Fukuoka Prefecture with the cooperation of architect Kengo Kuma, has sparked heated debate on 5ch following an Asahi Shimbun report. Assembly Speaker Kurauchi said the monument “will be appreciated in the future,” but thread posters repeatedly questioned whether the construction cost was justified and raised concerns about maintenance expenses.

What people said
No doubt about it.
It's Kuma everywhere you look, literally (a pun: 隈なく/kumanaku means "thoroughly, everywhere," playing on the "Kuma" in his name).
You know his buildings are designed so you can't get any repairs done without going through his own firm, right?
Uh, it's already in its 4th year though?
He gets to keep skimming off the ongoing maintenance costs.
Wait, it's NOT made of wood?!
The One Health Carbon Gate, built at a cost of about ¥280 million — Chikugo City, Fukuoka Prefecture
So THIS is what ¥300 million buys.
Looks like about ¥30 million worth to me.
They're skimming so much it's almost impressive.
Why not just slap a gold plaque on it that says "¥280 Million Monument by Kengo Kuma"?
I'll even chip in about ¥5 million for it.
That's what you'd think, right?
But this one's even worse.
There's gotta be some kind of racket going on with these guys.
He's got a track record, so everyone knows what they're getting and it's easy to work with him.
Track record of what, you ask?
it's painted, so after a while they'll rack up costs repainting it (´･ω･`)
Since it's painted, I'm skeptical it's actually carbon fiber.
Stuff like this factors in "idle time" costs for the periods with no work coming in, so of course it's pricier.
If you've got a problem with it, you could've just started your own company and bid lower.
That's about the intellectual ceiling of the "it's all skimming" crowd 😩
Well, what's built is built, so how about we put up a plaque listing:
the cost paid from taxes,
who decided to place the order,
and the representative of the company that got the contract.
and it's notoriously unpopular because it's such a pain to actually use.
Fun fact: Kengo Kuma actually lost the competition for his own hometown Kamakura's new city hall building.
Pick your jobs more carefully, man.
What if "Kengo Kuma the architect" doesn't actually exist, and it's just a public front name for the government to embezzle money?
If it's reasonable, there's nothing to fear.
They set a budget estimate and put it out for bid, so of course it's "reasonable."
And since the amount would've needed assembly approval to contract, who exactly is supposed to be afraid here?
You can walk through it, right?
Who even is this guy? His name keeps popping up everywhere —
the Expo, some regional city hall…
Is he like a big shot in the construction world or something?
Background and Key Points
Kengo Kuma is Japan’s most prominent contemporary architect, known internationally for the wood-and-organic-material aesthetic of projects like the Japan National Stadium (2020 Olympics) and V&A Dundee. That reputation is why his name recurs across Japanese public projects, from World Expo pavilions to municipal buildings — local governments treat a Kuma-designed structure as a branding win, a way to signal design credibility for a relatively modest architectural fee. The “One Health” concept in the gate’s name refers to a public health framework, popular in Japanese local government messaging, that links human, animal, and environmental health; Chikugo City has promoted it as a civic theme, which is the stated rationale for commissioning a landmark structure at all. Fukuoka Prefecture assembly budgets for such symbolic public works are approved through prefectural assembly votes, meaning the roughly ¥300 million (about $2 million) figure was disclosed and authorized in advance, not a hidden overrun.
The thread’s actual disagreement was not over Kuma’s involvement itself but over value for money: whether the finished carbon-fiber gate looks like it cost anywhere near ¥280 million, with posters comparing it unfavorably to inexpensive playground equipment, versus a smaller group arguing that competitive bidding and idle-capacity costs baked into public contracts make the price defensible on paper.
What the thread never engages with is that “reasonable per the bid process” and “good use of public funds” are separate questions — a budget being procedurally approved doesn’t resolve whether the chosen design concept was worth funding in the first place. Also unaddressed: ongoing maintenance liability for painted carbon fiber in outdoor conditions is a real recurring cost, not just cynical speculation about “skimming.”
