On a street corner in Tsuruhashi, Osaka, stands a vending machine that sells only ponzu. Emblazoned with "Money back if you don't like it," the machine holds the life story of a man who went from banker to fugu chef, and a dose of Osaka merchant spirit.

The Birth of Tsuruhashi's Ponzu Vending Machine

Osaka's Tsuruhashi district is known for its lively yakiniku restaurants and Korea Town. Step off at JR Tsuruhashi Station and the savory smell of grilling meat greets you, along with rows of shops selling Korean ingredients and kimchi. Tucked into this bustling neighborhood stands an unusual vending machine.

Inside, you won't find canned coffee or bottled water. It's stocked entirely with ponzu, a citrus-based Japanese condiment. Across the front, in bold letters, is the phrase: "Money back if you don't like it!"

It's run by Ko Heiretsu, chairman of Upper Corporation. Today, seven of these machines operate around the Tsuruhashi area, a distinctive part of the local scenery.

From Banker to Fugu Chef

Ko was born and raised in Tsuruhashi. After 21 years as a banker, at the age of 50 he made a major change: he opened the fugu (pufferfish) restaurant he had long dreamed of, called "Toraya."

The road was far from smooth. His first venture failed and left him struggling. But he refused to give up, taking part-time work to get by while earning his culinary license and returning to the kitchen.

Toraya ran as a tecchiri (fugu hotpot) specialty restaurant for ten years before closing. Yet one flavor born in that kitchen became the seed of his next venture.

The Craft Behind "Gold Ponzu"

The homemade ponzu he served was built on Yuasa soy sauce from Wakayama, prized as one of Japan's finest, with carefully chosen ingredients layered in: bonito flakes from Makurazaki in Kagoshima, kombu from Rishiri in Hokkaido, and shiitake from Oita, finished with sudachi and yuzu from Tokushima.

The result earned a place in the Japan Ponzu Council Hall of Fame, and Ko became known as the "Ponzu Master."

There are several products. The standard Tsuruhashi Ponzu sells for ¥450 (200ml) or ¥750 (365ml). The Tsuruhashi Kimchi Ponzu, blended with gochujang, nods to the Korean culture rooted in the neighborhood. At the top sits "Gold Ponzu," ¥1,500 for 365ml, flecked with gold leaf; it's popular as a good-luck gift, and students facing exams sometimes buy it.

"Mottainai" Thinking Sparks a Vending Machine Business

Why sell ponzu from vending machines? The idea came from Ko's sense of "mottainai," the Japanese distaste for waste.

Seeing old vending machine units discarded by sake shops closing down, he thought they still worked fine and could be reused to sell ponzu.

The appeal was clear: round-the-clock availability, lower labor costs, and, above all, novelty. Selling a condiment this way drew repeated media coverage, including MBS's "Sando no Meshi yori Are ga Suki!" and Yomiuri TV's "Osaka Honwaka TV."

What "Money Back If You Don't Like It" Really Means

The line on the machine isn't just marketing copy. It reflects Ko's confidence in the product and his pride as an Osaka merchant.

In fact, the only refund ever requested involved a container that had been dented. That track record says plenty about the quality behind the guarantee.

"Gold Ponzu is a 'happiness-bringing ponzu.' I want it to help bring families together," Ko says. Having taken the long road through setbacks, every drop carries the warmth of someone who wants to please his customers.

Japanese Vending Machine Culture and Local Specialties

Japan is one of the world's great vending machine nations. As of the end of 2024, about 3.91 million machines were operating nationwide, and adjusted for population and land area, Japan is often said to have the highest density anywhere.

Machines once meant mostly drinks and cigarettes. But convenience-store coffee has eaten into canned-coffee sales, and as the number of smokers falls, tobacco machines are disappearing too.

Filling the gap are quirky machines selling local specialties. Shizuoka's "Chabacco" sells tea in cigarette-style packaging; fresh-squeezed orange juice machines have appeared in cities. The Tsuruhashi ponzu machine is one more emblem of this new wave.

Japan's Vending Machines Draw Global Attention

For visitors to Japan, the sheer number of vending machines is a source of wonder. They run safely around the clock, dispense hot and cold drinks from the same unit, and accept cashless payment, packing in a lot of technology.

Most of all, there's the thrill of not knowing what might be inside. Canned oden, ramen, gyoza, and now ponzu. Hunting down unusual vending machines has become a small pleasure of travel in Japan in its own right.

Every region of Japan has beloved local condiments and specialties: miso, soy sauce, dashi, various sauces. Maybe your hometown has something that would make an interesting vending machine product too.
