The story
A debate broke out on the Nandemo Jikkyo G board over the difference between okonomiyaki sauce and takoyaki sauce. When the poster explained to a friend in Tokyo that “they’re totally different things,” the friend wouldn’t budge — “they’re both just sauce,” “they’re both brown” — and the thread spiraled into opinions on Gindaco (a major takoyaki chain) and the lineage of sauce makers like Ikari Sauce, Otafuku Sauce, and Bulldog Sauce.
What people said
Tokyoite: "Isn't it all just sauce?"
Me: "…"
Real Osaka takoyaki is where it's at.
Why do Osaka people hate Gindaco so much?
What's "real" even mean? The mushy ones that look like balls?
You're seriously eating that soggy, gross takoyaki? Are you out of your mind? 🤣
No way they're the same lol. These guys really do have dumb taste buds.
Don't dodge with vague stuff like "richness" or "aroma" — talk ingredients.
Tokyoite: "They're the same color though."
Says the guy who can't even tell sauces apart by taste.
That's basically the answer to every sauce dish.
You seem like the type who'd like La Muu (a discount supermarket chain).
At least La Muu beats choosing Gindaco.
La Muu is dangerous, let's set that aside for now.
Kansai person: "Can't argue with that."
Kanto person: "Modan-yaki (okonomiyaki with fried noodles mixed in) is the best of all."
This is reality.
Wish the Gindaco faithful would quit being jealous of Osaka.
Just stirring up conflict to bump the thread. Pathetic.
It's fried octopus, that's why.
Gindaco actually sells more though, just saying.
When you think Tokyo sauce maker, it's Bulldog Sauce.
By the way, Osaka's Ikari Sauce is actually a subsidiary of Tokyo's Bulldog Sauce.
It's Otafuku Sauce, actually.
Wild that mixing it with ketchup basically makes demi-glace.
Takoyaki sauce is spicier though.
Tokyoite: "Wait, aren't they the same sauce?"
Me: "Not even close. Okonomiyaki sauce is sweet and thick, takoyaki sauce is thinner with more of a dashi flavor."
Tokyoite: "But they're both brown."
Me: "That's not the point."
Tokyoite: "Yakisoba sauce is the same too, right?"
Me: "……"
The world of konamon (Osaka's flour-based food culture) runs deeper than I thought.
Drop the puppet-show dialogue and just show us the real sauce.
Otafuku Sauce is for okonomiyaki and takoyaki.
What even is Ikari Sauce, never heard of it.
Ugh, not funny.
They're all just vegetable-simmered sauces anyway, right?
You probably wouldn't notice if it was soy sauce either.
Osakan: "……Takoyaki sauce."
Tokyoite: "How do you even know?"
Osakan: "Because I eat it every day."
Tokyoite: "To me it all just looks like sauce."
Osakan: "It's not about how it looks, it's about the taste."
Like a Kansai person would even understand "taste" lol.
What manga is this from?
Background and Key Points
Sauce culture in Japan is more codified than it looks to outsiders. Under Japan’s agricultural standards (JAS), Worcestershire-style sauces are actually classified into a spectrum by viscosity alone — usutā (thin), chūnō (“medium-thick,” the everyday table sauce), and nōkō (thick, used for tonkatsu, okonomiyaki, and takoyaki) — all built from the same base of vegetables, fruit purée, vinegar, and spices, just concentrated to different degrees. Okonomiyaki and takoyaki both grew out of Osaka’s konamon (flour-based food) culture, and the sauces marketed for each are formulated slightly differently even within the nōkō category: okonomiyaki sauce leans sweeter and thicker to cling to a flat, griddled surface, while takoyaki sauce is cut thinner and more dashi-forward so it coats round balls without pooling. Regional makers like Otafuku (Hiroshima/Osaka-linked) built their whole product lines around this distinction.
The thread’s actual fault line isn’t really about chemistry — it’s about whether visual/categorical sameness (“it’s all brown,” “it’s all sauce”) overrides lived taste memory, with the Osaka poster unable to articulate the difference in terms a non-eater would accept beyond “I just know.”
What outsiders likely misread is the sauce-lineage trivia in the thread itself (Ikari being a Bulldog subsidiary, or actually Otafuku) — the posters contradict each other and neither claim is confirmed there, so it should be read as thread lore, not verified corporate history. Also overlooked entirely: Gindaco, mocked here as inauthentic, is Japan’s largest takoyaki chain by revenue, meaning the “authentic Osaka” preference expressed in the thread is a minority taste nationally.
