Seattle teriyaki is not the same dish as teriyaki in Japan. It is a Japanese-American invention — a grilled chicken thigh lacquered with a thick, sweet soy-sugar glaze, served over a mound of steamed white rice with a pile of shredded iceberg or cabbage dressed in ginger vinaigrette. The plate is large, the price is low (usually $10-15), and the format is fast-casual: counter service, often styrofoam containers, open for lunch and dinner.
In Japan, teriyaki is a cooking technique — the word means 'shiny grilled' — applied mainly to fish such as yellowtail, mackerel, or salmon, in small portions as part of a multi-course meal. The Japanese sauce is thin, lightly sweet, and made with soy sauce, sake, and mirin rather than sugar. What Seattle created is something distinct: an American dish that borrowed the name, kept the glaze concept, and built an affordable fast-casual format around it. That format has now expanded to more than 200 shops spread across the city and its surrounding neighborhoods.
Toshihiro Kasahara emigrated from Ashikaga City, Japan, to study business in the Pacific Northwest. On March 2, 1976, he opened Toshi's Teriyaki at 372 Roy Street in Lower Queen Anne — generally cited as the first stand-alone teriyaki shop in the United States. His formula broke with the Japanese tradition he had grown up with in several ways: he replaced mirin with granulated sugar (cheaper, sweeter, more consistent at scale), used chicken thighs rather than fish, grilled them over charcoal, and served the whole thing over white rice with shredded iceberg. The price was low. The portions were large. Office workers, students, and neighbors bought it by the container.
Kasahara sold the Roy Street location in 1980 and began franchising the format. New owners came from a range of backgrounds — Japanese, Korean, Chinese, Mexican, Indian, and Caucasian-American entrepreneurs all ran Toshi's franchise locations. By 1996, he had grown to 17 locations in the Seattle area. Korean-American entrepreneurs in particular shaped what came next. John Chung, a Korean immigrant who developed his own teriyaki recipe in 1979, trained an estimated 100 Korean immigrants in his business model, spreading the format through South Seattle and into surrounding neighborhoods. Eater has called him 'the unsung godfather of Seattle's favorite comfort food.'
By 1992, King County had 107 businesses with 'teriyaki' in their name. By 1996, the count had risen to 175. By 2007, Seattle proper had more than 100 teriyaki shops and only 12 McDonald's within city limits. Today the metro area has more than 200 teriyaki shops across King County. Food writer and Seattle resident J. Kenji Lopez-Alt launched a public quest in 2024 to eat at every teriyaki shop in the city, describing the dish as 'a very democratic food' and comparing its role in Seattle to what pizza is to New York.

Four things distinguish the Seattle version from its Japanese ancestor.
The sauce. Japanese teriyaki sauce is soy sauce, sake, and mirin — thin, lightly sweet, brushed on in layers to create a lacquer sheen. Seattle teriyaki sauce is soy sauce, sugar, and often a cornstarch thickener — thick, very sweet, and ladled generously over the plate. The sweetness is the most immediately noticeable difference when you eat the two side by side.
The protein. Japanese teriyaki is primarily a fish preparation — yellowtail, mackerel, or salmon, in modest portions. Seattle teriyaki is almost always chicken thighs, sometimes beef sirloin, occasionally pork or tofu. Using chicken as the default protein is a Japanese-American adaptation that does not exist in the same form in Japan.
The presentation. Seattle teriyaki arrives as a complete, filling meal: a significant pile of rice, the protein on top, a salad alongside, and sauce pooling at the edges. A Japanese teriyaki preparation arrives as part of a multi-course set meal in much smaller portions. The Seattle plate is designed to fill you up for under $15, not to accompany other dishes.
The cultural lineage. Korean-American shop owners, more than any other group, have shaped what Seattle teriyaki has become over the past four decades — sometimes adding kimchi on the side, adjusting spice levels, or developing house sauces that go beyond Kasahara's original formula. The dish is a genuinely multicultural creation.
The standard order at any Seattle teriyaki shop is a chicken thigh plate or a combo plate (chicken and beef). Here is what to expect and what to ask for.
The chicken plate is the benchmark: two or three bone-in chicken thighs, grilled and glazed, over a large serving of white rice, with a heap of shredded iceberg or cabbage and ginger dressing. Most shops include a small cup of miso soup. Price: $10-13.
The combo plate adds sliced beef sirloin alongside the chicken, grilled separately and served on the same bed of rice. Price: $13-18. It costs more but gives you both textures — the caramelized chicken and the thinner, faster-cooked beef.
Ask for extra sauce on the side. The sauce already on the plate is usually enough for the chicken, but a side cup lets you add more to the rice and salad where it absorbs quickly.
The salad is understated but important: shredded iceberg dressed with a thin ginger vinaigrette, sometimes a few slices of cucumber. Eat it while it is still cold. By the time you finish the rice and chicken, the heat from the plate will have wilted it.
Most shops also offer salmon teriyaki, beef teriyaki, and vegetarian tofu plates. The salmon plate is common and works well — the sweet glaze pairs naturally with the fat content of the fish, and it is closer in spirit to what teriyaki means in Japan than anything else on the menu.
Seattle's teriyaki landscape is large and democratic — most shops are independently owned, and quality is generally high across the city. These five have sustained reputations worth knowing. Details verified October 2026; hours and prices change, so confirm before you go.
Rainier Teriyaki — Mount Baker (3330 Rainier Ave S). The Infatuation's pick for the best teriyaki in Seattle. Known for a smokier char than most shops, with a caramelized sauce that sets it apart from the sweeter standard. Rainier Ave S is the heart of Seattle's classic teriyaki corridor — the stretch from Mount Baker south through Columbia City has a higher density of longtime shops than any other part of the city.
Manna Teriyaki — Lake City (11064 Lake City Way NE). One of the highest-rated shops in North Seattle according to The Infatuation. Known for consistent quality and generous portions. Order the chicken thigh plate and add a pork egg roll. The Lake City Way NE corridor has a strong cluster of independent teriyaki shops worth exploring.
I Love Teriyaki — Fremont (3409 Stone Way N). A steady lunch institution in the Fremont neighborhood, drawing office workers from the tech corridor along Stone Way. The chicken plate is a reliable, well-glazed version of the Seattle standard.
I Love Teriyaki — Ballard (6421 15th Ave NW, Ste A). A second location in Ballard that serves the neighborhood's mix of longtime residents and newer arrivals. Similar quality to the Fremont location with a slightly quieter dining room at lunch.
Toshi's Teriyaki Grill — Mill Creek (16212 Bothell Everett Hwy Ste G). About 20 miles north of Seattle proper, Toshihiro Kasahara still cooks at this shop. The original Roy Street location in Lower Queen Anne is long gone, but this is as close as you can get to the source. The sauce is the same sweet, uncomplicated soy-sugar glaze from 1976. Worth the drive if the origin story matters to you.
Is Seattle teriyaki really an American invention? Yes. The dish as a standalone format — a full plate of glazed chicken thighs over rice, served at a counter for under $15 — was created specifically in Seattle by Toshihiro Kasahara in 1976 and does not exist in Japan in the same form. What you find in Japan labeled teriyaki is a cooking technique applied mostly to fish, as part of a multi-course set meal. They are related by a shared glaze concept but are functionally different dishes.
Why are so many teriyaki shops owned by Korean Americans? When Kasahara began franchising in the early 1980s, Korean immigrant entrepreneurs recognized the format's low overhead, broad appeal, and consistent demand and adopted it widely. They occasionally modified the sauce and preparation over time, and their influence is part of why Seattle teriyaki today has a slightly different character than Kasahara's original — sometimes spicier, sometimes with house sauces that go beyond the 1976 formula.
Is the original Toshi's still open? The original Roy Street location in Lower Queen Anne closed years ago. Toshihiro Kasahara operates Toshi's Teriyaki Grill in Mill Creek (16212 Bothell Everett Hwy Ste G). Details verified October 2026; confirm hours before making the trip.
When are teriyaki shops typically open? Most Seattle teriyaki shops run from roughly 11 a.m. to 9 or 10 p.m. Many close one day a week, often Sunday or Monday. Hours vary widely by shop — check Google Maps or call ahead before making a special trip.
