article thumbnail image

Kesennuma, located on the coast of Miyagi Prefecture, is a major fishing town. In particular, shark fin is known as a local specialty of Kesennuma. We visited Ishiwata Shoten, a shark fin store with a 50-year tradition, to learn what makes shark fin such a rare and treasured delicacy.

A well-known delicacy in Chinese cuisine, dried shark fin is often served in the form of a soup or stew. While there are many concerns around the sustainability of shark fin, Japan has a long history of utilizing shark in cuisine and has developed refined methods for processing sharks humanely and without waste.

Kesennuma in Miyagi Prefecture boasts the largest domestic catch of sharks, bringing in about 90 percent of Japan's total catch.

Kesennuma is located on the Sanriku Coast, one of the top three fishing grounds in the world. Its location makes Kesennuma a prime fishing town in the Tohoku region. The fleet of massive fishing boats docked in the harbor is an incredible sight to see!

The jagged topography of Kesennuma Bay is known as a "ria." By keeping the waves inside the bay calm, the ria helps cultivate plankton, a great source of nutrition for fish.

You'll also find local gifts and food at the nearby shopping center Naiwan.

A Rich Shark Culture


Before we introduce a tasty shark fin dish, let's take a look at the shark culture in Kesennuma. We talked to Hisashi Ishiwata, the representative director of Ishiwata Shoten, a shark fin store with over 50 years of history.

"Shark fishing and processing have been long-time traditions throughout Japan. The reason Kesennuma remains the largest producer of shark fin today is that we have a large presence of professionals who specialize in shark processing."

It's rare to find so many professionals gathered in a single city. Finning, the act of cutting off shark's fins and discarding the rest, has been a growing problem in some areas of the world. Fortunately, Kesennuma has a long-standing tradition of using the entire shark without waste.

"Sharks have no single part worth wasting. Their meat can be turned into kamaboko and chikuwa (*), while the bones and skin are excellent ingredients for health products."


Even a shark's heart, known as the star of moka (salmon shark), can be enjoyed as sashimi. You can only find these delicacies in a fishing town like Kesennuma!

*Kamaboko and chikuwa are two types of Japanese fish products made with fish paste.

Ishiwata Shoten - Recovering from Disaster


The view of Kesennuma in November 2020

On March 11, 2011, the Tohoku Earthquake and the subsequent tsunami devastated the city of Kesennuma.

"The harbor, market, and factories were all completely destroyed. Two out of the ten shark fin stores in Kesennuma had gone out of business."

Having lost almost everything, Ishiwata Shoten worked quickly to rebuild their factory. They were determined to protect the history of Kesennuma as the city with a rich shark-related cuisine and culture.


"If Kesennuma loses its processing factories, fishers will take their boats elsewhere. We had no idea about the future, but we knew we needed to rebuild our factories as soon as we could."

As devastating as the earthquake was, it had also brought a positive change.

"Before the disaster, shark fin stores were competing against each other. But in the aftermath, we all had to start from square one. This brought us together to revive the market in our city."

Mr. Ishiwata shared his story with strong passion for Kesennuma and its future.

Shark Fin at Ishiwata Shoten

Shark fin is a delicacy that you don't get to try often. What makes it such a valuable food?


"First off, only ten percent of the shark can be made into shark fin. If you divide the number of sharks caught in Kesennuma among the Japanese population, one person could eat shark fin once every 35 to 40 years. For this reason, shark fin is a precious commodity."

Kesennuma is primarily home to blue sharks. Compared to other sharks in the world, blue sharks are relatively small, thin, and gelatinous. By keeping them fresh and processing them carefully, you can prepare absolutely delicious shark fin.

"Shark fin is difficult to process because it takes meticulous manual work. We use a process called 'sumuki,' developed by my grandfather."

Sumuki involves removing excess skin, meat, and bones from raw shark fin, then using a purpose-built machine to dry it.

In the past, most shark fins were dried in the sun. The sumuki method makes it possible to fully process shark fins while they are still fresh. This ensures that the shark fins are high quality and safe to eat.

Shark Fin Steak! Experience Different Flavors

Now that we've learned how shark fins are prepared, let's find out how they taste.

"Since shark fins are very gelatinous, they will taste of gelatin. What makes shark fins interesting is how the flavors change once the gelatin mixes with cooking oil."


With that, Mr. Ishiwata brought out a shark fin steak. While shark fins are primarily served as a soup or stew in Chinese cuisine, the steaks at Ishiwata Shoten are a great way to better enjoy the flavor and texture of shark fins.

The shark fin steak has no artificial seasoning and very little salt. You can pan-fry it yourself at home.

"We added consomme soup to this shark fin, but the soup tastes quite different when it's combined with the shark fin."


The center of the shark fin is said to be the most delicious. It has a chewy texture and adds a layer of richness to the consomme soup. We were taken aback by how tasty it was!

"The textures and flavors of shark fin change depending on how it's cooked and seasoned. It is a unique food, almost like a science experiment."


The more Mr. Ishiwata shared his story with us, the more we were drawn to the deep culture of shark fins. Visit Kesennuma to savor this delicacy yourself!

The oysters used for the oyster sauce are sourced from Karakuwa, a renowned Kesennuma oyster farm. These oysters are especially healthy, due to the abundance of plankton in the area. They are harvested between March and May when the oysters are largest.

"Normally, oysters are boiled down into dashi (*). But we extract the flavor straight from whole oysters. We developed our oyster sauce so you can enjoy the best flavors of Kesennuma oysters, wherever you are and at any time of year."

Use this oyster sauce at home to bring a delicious seafood flavor to any dish!
