Matsumoto Shave Ice at 75: The Accidental Shave Ice Shop of Haleʻiwa

Here is a thing I believe: most of the places we love were not supposed to become the places we love.

They were supposed to be something else. A side project. A stopgap. A way to get through a slow month. And then people kept showing up, and the thing that was meant to be temporary quietly became permanent, the way a nickname does, or a friendship you didn’t notice starting until you realized it was holding up a good portion of your life.

Matsumoto Shave Ice in Haleʻiwa is one of those places. Today it is quite possibly the most famous shave ice shop in the world: a weathered storefront on Kamehameha Highway with a line that drifts toward the road on pretty much any day the sun is out (which, on the North Shore, is a lot of days). The family has said the shop serves more than a thousand orders a day. People plan vacations around it. People who have never set foot in Hawaiʻi own the T-shirt.

But it did not start as a shave ice shop. It started as a grocery store. And before that, it started as a favor.

A building with two families in it

To understand Matsumoto’s, you have to start with a different family, and a building that was already old by the time the Matsumotos arrived.

Around 1904, a wood-frame building went up in Haleʻiwa. It belonged to Sego and Tayo Tanaka, immigrants from Ehime Prefecture on Japan’s Shikoku Island, who ran a tailor shop and dry goods store inside. When they returned to Japan in the 1920s, their son Kazuaki stayed behind. He and his wife Shizuko kept the business going as the K. Tanaka Store, and Kazuaki became one of the most respected businessmen on that side of the island.

Then came World War II, and Kazuaki Tanaka, like many Japanese American community leaders in Hawaiʻi, was interned. Shizuko kept the store open until 1944, when she and their son were sent to join him at a family internment camp in Crystal City, Texas. Kazuaki’s brother Masakazu ran the shop while they were gone.

I want to pause here, because it would be easy to hurry past this part on the way to the shave ice, and I don’t think we should. A man built a life, had it taken from him by his own government, and came home in 1945. And what he did next was not retreat. In 1950, he opened The Esmond, Haleʻiwa’s very first department store.

Which left the old store building without a purpose. And Kazuaki Tanaka happened to know a young couple who had been dreaming, for years, of owning a business of their own.

The dreamers

Mamoru Matsumoto was born in Honomū on the Big Island, but his family moved back to Hiroshima when he was a toddler. As a young man, finding few opportunities in Japan, he came back to Hawaiʻi and did what a lot of people did back then: whatever work there was. Sugar plantation. Railroad. Selling goods for a store in town. In 1937, he married a Hilo girl named Helen Ogi at the Haleʻiwa Jodo Mission.

By 1951, they had two kids and a third, Stanley, on the way. That year, Kazuaki Tanaka sold them the K. Tanaka Store. On February 13, 1951, M. Matsumoto Store opened its doors.

It was a grocery store in a sleepy plantation town. Haleʻiwa was not yet the surf capital of anything. Mamoru reportedly peddled goods around town on a bicycle while Helen ran the counter, and they kept the lights on late in the hope that people walking home from the town’s movie theaters might stop in for something.

The slow month that changed everything

Here is my favorite part of the whole story, and possibly my favorite small-business origin story of all time.

In 1956, business was slow. And a family friend suggested, more or less: Hey, why don’t you sell shave ice?

That’s it. That’s the origin. Not a business plan. Not a vision board. Just a friend noticing that things weren’t going great and offering an idea.

Shave ice wasn’t new, of course. Kakigori, shaved ice with sweet syrup, has been a summer treat in Japan for something like a thousand years, and in Hawaiʻi, where it is basically summer forever, it made perfect sense. The Matsumotos served theirs with homemade syrups and sweet azuki beans, and the town loved it.

Then the 1960s happened. Surfers from California began arriving on the North Shore, plenty of them on one-way tickets, chasing winter waves bigger than anything they’d seen back home. Haleʻiwa was the gateway to those waves. And after a long day in the water, a mountain of cold, sweet, rainbow-colored ice from the little store on Kamehameha Highway turned out to be exactly what a sunburned twenty-year-old wanted.

Slowly, and then all at once, the groceries gave way. The shave ice took over.

Seventy-five years later

Stanley Matsumoto, the baby born the same year the store opened, took over from his parents in 1976. With his wife Noriko and, later, their daughter Remy, he turned the family store into one of the most beloved multigenerational businesses in Hawaiʻi. The shop now sells T-shirts and souvenirs alongside the shave ice, and its logo has traveled to more places than most of us ever will.

In February 2026, the shop turned 75. It celebrated the way you’d hope it would: live music, and one-dollar small shave ice for a day, a thank-you to the community that never stopped lining up.

The building is still there, too. The North Shore Chamber of Commerce has placed a bronze plaque on it, one of a series of markers around Haleʻiwa, telling the story of both families who built their lives inside those walls across more than a century.

Why this story matters

I think we tend to imagine that great businesses are built by lone geniuses with perfect timing. And sometimes, sure. But the more stories like this one I hear, the more I suspect that most enduring places are built the way Matsumoto’s was: by a lot of people being decent to each other over a long stretch of time.

A family that sold their store to a young couple with a dream. A friend who suggested shave ice during a slow year. Parents who stayed open late. A son who kept the doors open for another half century. And millions of strangers who, simply by showing up and standing in line, turned a slow month in 1956 into something that has outlasted almost everything around it.

So if you find yourself on the North Shore, go. Stand in the line. (The line is part of it. The line is where you meet the people who drove an hour for the same reason you did.) Order a rainbow. Add the azuki beans if you’re brave and ice cream on the bottom if you’re wise. And while you eat it, maybe think about the Tanakas, and the Matsumotos, and the friend whose name doesn’t appear in most tellings of this story, who looked at a struggling grocery store and said, more or less, what about ice?

Small kindnesses, it turns out, can last seventy-five years.
