The Evolution of Flavor: A Guide to Regional Teriyaki Styles

Teriyaki is loved around the world, but few home cooks know the rich history behind the sauce on their plates. Real teriyaki started in small family kitchens and independent restaurants. It was made by people who understood how to balance simple ingredients.

Today, grocery store shelves are full of mass-produced brands that use added water, thickeners, and additives to make more money. But the true spirit of this iconic flavor lives on through independent businesses that stick to their roots.

Geography and history completely changed how we eat this classic dish today. By learning the differences between Traditional Japanese, Seattle, and Hawaiian styles, you can understand the roots of real teriyaki and make your own home cooking even better.

Traditional Japanese Teriyaki: The Edo Origins

To understand modern sauces, we must look back to the Edo period in Japan (from the 1600s to the 1800s). The word itself explains how it is cooked: "teri" means shine or glaze, and "yaki" means grilled or broiled.

Traditional Japanese Teriyaki is typically not a thin, watery marinade. Instead, it is a thick, boiled-down mix of soy sauce, mirin or sake, and sugar. Cooks use this simple mix only as a final glaze. They brush it over fish or chicken right before it finishes grilling to create a beautiful, sweet coating.

This respect for simple cooking is the base of Bungoyaki. In 1965, our grandparents Kazutoshi and Yoshiko Ojiro immigrated from Japan to Los Angeles to open Bungo Restaurant. There, they started serving their own traditional Japanese dishes, with their original Bungoyaki teriyaki recipe becoming a local staple. Their 6-ingredient blend included ginger and garlic for extra flavor and was often paired with beef, chicken, and salmon. They spent over 40 years perfecting their work. By the time they retired, they didn’t even need to measure their ingredients when making each batch of sauce. Making the perfect teriyaki was second-nature. They simply looked at the ingredients to get the exact thickness and taste that defined their family name.

Seattle-Style Teriyaki: The Fast-Casual Trend

Up the coast, a different variety of the dish was forming in the Pacific Northwest. Seattle-Style Teriyaki started in 1976 by Japanese immigrant Toshi Kasahara. When he opened Toshi's Teriyaki Grill in Seattle, he started a local trend of independent teriyaki shops.

This regional style was made for quick, filling meals. Many Seattle teriyaki shops make a sauce that is much sweeter than the Japanese original, while typically adding cornstarch to thicken the sauce fast. This gives it that thicker, stickier coating that has become well-known for Seattle-style teriyaki sauces.

Toshi Kasahara is still a hero of this independent spirit. His business continues to bottle his original sauce, known as Toshi's Teriyaki. Even though many local shops use garlic and ginger today, Toshi's own bottled recipe keeps things simple. He skips those extras and uses basic ingredients like soy sauce, cane sugar, and rice vinegar in his small batches.

Hawaiian-Style Teriyaki: The Plantation Heritage

Across the ocean, the islands of Hawaii created their own unique version of the sauce. Hawaiian-Style Teriyaki was made by Japanese immigrants who arrived in the late 1800s and early 1900s to work on sugar farms. These workers changed their traditional recipes by mixing classic soy sauce with local brown sugar and fresh ginger.

This change created a flavor that is much sweeter than traditional glazes. In Hawaii, teriyaki is often used as an overnight marinade. It is also served as a thick sauce poured over famous Hawaiian plate lunches.

The spirit of family business is just as strong on the islands. A perfect example is the Aloha Shoyu Company, often just called Aloha brand. It was started in 1946 by five local families in Oahu. Their goal was to bottle their own island-style soy sauce and teriyaki. Today, Aloha Shoyu is still a huge, independent favorite that honors its founding families.

Why Independent Roots Matter

In a grocery store filled with giant brands and watered-down sauces, knowing the history of your food matters. Whether you like the balanced flavor of Traditional Japanese Teriyaki, the comforting taste of Seattle-Style Teriyaki, or the deep sweetness of Hawaiian-Style Teriyaki, the best flavors always come from real family traditions. Brands like Toshi's and Aloha prove that you do not need a big corporation to make a great product.

At Bungoyaki, we share that same belief. Our goal is to make a simple, honest teriyaki that respects our grandparents' original 1965 recipe. We never add water or fake fillers.
