Popcorn? Miso. Soft serve? Miso three times over.
I went around Maruya Hatcho Miso and Kakukyu Hatcho Miso in Hatcho, Okazaki. What started as a factory tour and souvenir hunt led to food, wooden vats and even manhole cards. Somehow every path came back to miso.
No. 1 being Hatcho miso makes sense; No. 2 being miso-katsu sauce gets oddly specific
A popularity display seen at Maruya’s shop put Hatcho miso at No. 1 and miso-katsu sauce at No. 2.
The first is obvious. You visit a Hatcho miso brewery and buy Hatcho miso. That is the final boss of sensible souvenir shopping.
Then No. 2 suddenly narrows the use case to “people who plan to make miso-katsu at home.” It feels less like a generic tourist ranking and more like local food culture quietly showing its hand.
One companion immediately chose the No. 1 product for miso soup. The reason was simple: they were a big fan of the flavor of Kibusachi’s Tokai Hatcho Taiwan-style ramen.
That connection is real. The official Okazaki tourism site states that Kibusachi uses Maruya Hatcho Miso in both its Sanshu Okazaki Miso and Tokai Hatcho Taiwan ramen. Okazaki’s Kibusachi guide
You like the ramen, find out which miso it uses, and buy that miso to take home.

At Kakukyu Hatcho Village, almost nothing escapes miso
Cross over to Kakukyu and the density rises.
Its official restaurant promotes dishes such as miso-nikomi udon and miso kushikatsu. Kakukyu’s restaurant The shop carries sweets made with miso. The signature miso soft serve mixes miso into the cream, adds Hatcho miso powder, and finishes with a miso rice cracker. Kakukyu itself describes it as thoroughly packed with miso. Kakukyu’s shop
Then there is miso popcorn. Kakukyu’s official online shop describes it and highlights its sweet-salty taste and Hatcho miso powder. Kakukyu’s snacks
At a normal tourist attraction, there might be one novelty product made with the local specialty.
Here, the pattern feels more like:
Popcorn? Miso. Soft serve? Triple miso. Kushikatsu? Miso. Udon? Miso.
You can imagine every product meeting going the same way:
“Can we put miso in this?”
“Yes.”
Approved.
If someone scanned the planning department’s brain, the cerebrum would probably be Hatcho miso, the cerebellum red miso soup, and the cerebrospinal fluid dashi. That is obviously a joke, but the thematic consistency is genuinely intense.
Looking for Tetsuya, I found a Rune manhole card
Hatcho is also part of Okazaki’s Tokai On Air pilgrimage network. Search for related stickers or memorabilia, and you can suddenly fall into a completely different quest: manhole cards.
According to Okazaki City’s official guide, the Tokai On Air “Tetsuya” manhole card is distributed at Maruya Hatcho Miso. Kakukyu Hatcho Miso Village, meanwhile, distributes the gray “Rune” manhole card. Okazaki’s manhole cards
That swap is wonderfully confusing.
You arrive in the neighborhood following Tetsuya, ask at a Hatcho miso facility, and suddenly meet Naito Rune instead.
Rune was an artist from Okazaki, and the city has installed multiple color variations of manholes featuring Rune Girl and Rune Panda. Okazaki’s manhole designs
For anyone who did not know that in advance, the experience can feel like:
“I have come to a place I did not know, for a person I did not know.”
At the counter, visitors getting a card were counted as local, from outside the city, or from overseas. The tally I saw was only a handful of people. It was amusingly small, but accepting a card would put me in that count too.
I followed Tetsuya and ended up being counted as a visitor to a sewer publicity event.
Workers really do step into the vat—so is human sweat the secret ingredient?
The factory’s huge wooden vats led to another question: how do they make this?
Maruya’s official process really does show workers entering the vat, leveling the mixture, and pressing it down with their feet. The purpose is to remove excess air and create the base for the heavy stone weights. Maruya’s production process
Seen without context, it invites the thought:
“Wait, are sweat and skin microbes helping ferment this too?”
The producer’s explanation points to yeasts and lactic-acid bacteria living in the brewery, rather than workers’ sweat. Soybean koji is mixed with salt and water, the air is pressed out, and fermentation takes time. The company says its wooden vats are used for about 100 years on average. The microbes’ home might be older than the worker there today. Maruya’s miso
Take a detour, and miso still finds you
Come to buy miso and you find miso-katsu sauce and popcorn too. Follow your favorite ramen’s flavor and you reach the miso it uses. Follow Tetsuya and the card pickup point is a miso brewery.
I thought I was taking a detour, but miso was waiting on every road.
Every exit on the Hatcho map has miso at the end.
An ordinary theme park builds a world for its visitors. Here, centuries of making miso seem to have turned the real neighborhood into a miso world.
