Why Men-Eiji broth is called gyokai-tonkotsu
In ramen terminology, a broth’s name often tells you what creates its character. “Gyokai-tonkotsu” combines two Japanese food words: gyokai, meaning seafood, and tonkotsu, meaning pork bones. Together, they describe a soup in which seafood-based umami meets the body and richness of a pork-bone stock.
That pairing is the defining idea behind MEN-EIJI RAMEN in Sapporo. The restaurant’s signature broth is built around the contrast between marine depth and the rounded texture associated with tonkotsu ramen. It is a fuller explanation than simply calling the soup “seafood ramen” or “pork ramen.”
The name also helps explain why a bowl at MEN-EIJI can taste powerful without relying on one-dimensional heaviness. Seafood contributes aroma, salinity, and savory complexity, while pork bones provide gelatinous richness and a creamy foundation. The result is a layered broth with a distinct Sapporo identity.
What the Japanese name means
Gyokai is a broad Japanese culinary term for seafood and seafood products. In ramen, it may refer to the use of fish, shellfish, dried seafood, or other marine ingredients that contribute concentrated umami. It does not describe one single species or a fixed recipe. Instead, it identifies the ocean-focused side of the flavor profile.
Tonkotsu literally means “pork bones.” Tonkotsu broth is generally associated with pork bones simmered until their collagen, fat, and marrow create a dense, opaque soup. Depending on the preparation, the result can be creamy, savory, and richly textured, with a lingering finish.
When these terms are joined, the name indicates a combination rather than a garnish. Seafood is not merely placed on top of an ordinary pork broth, and the pork stock is not simply flavored with a little fish sauce. The two foundations are developed as part of the same ramen concept, creating a broth in which each side supports the other.
Two foundations in one bowl
Pork bones give tonkotsu broth its physical weight. Long cooking extracts gelatin and fat, producing a smooth mouthfeel that coats the palate. That texture allows the soup to carry noodles and toppings with confidence, giving the bowl a substantial presence even before additional seasoning is considered.
Seafood brings a different kind of intensity. Fish and other marine ingredients are valued for their natural glutamates and concentrated savory notes. These flavors can add brightness, fragrance, and a clean length to the finish. Their character is often more aromatic than the deep, fatty fullness of pork.
The appeal of gyokai-tonkotsu comes from the interaction between these elements. Pork can soften sharp seafood notes, while seafood can make a rich pork base feel more articulate and complex. Properly balanced, the broth has depth without becoming flat, and richness without losing its sense of direction.
This is why the term is useful for understanding MEN-EIJI’s style. It points to the source of the broth’s intensity while leaving room for the restaurant’s own seasoning, cooking method, noodle choice, and regional expression.
How the broth builds depth
A successful blended broth depends on balance at several stages. The pork-bone base must have enough body to support the seafood component, while the seafood side must remain recognizable after meeting such a powerful foundation. If either element overwhelms the other, the soup loses the layered quality suggested by its name.
Texture matters as much as flavor. A broth can contain seafood ingredients yet still feel thin, or it can be thick and creamy while offering little aromatic definition. Gyokai-tonkotsu aims for both: a substantial soup that carries savory marine notes through every mouthful.
Seasoning then shapes how the underlying stock is perceived. Salt can emphasize clarity and seafood fragrance, while soy-based seasoning may add roasted, fermented, and savory depth. The particular tare and finishing ingredients determine whether the bowl tastes more direct, rounded, smoky, or fragrant.
This is also why the first sip may not reveal everything. The pork texture tends to arrive immediately, but the seafood character can unfold as the broth warms the palate. Noodles, toppings, and aromatic oils further change the way the soup develops from the first bite to the last.
| Broth style | Main character | Typical mouthfeel | What seafood contributes |
|---|---|---|---|
| Tonkotsu | Pork-bone richness | Creamy, dense, and coating | Little or no marine character unless added separately |
| Gyokai broth | Seafood umami and aroma | Clear to concentrated, depending on preparation | Salinity, fragrance, and savory depth |
| Gyokai-tonkotsu | Seafood layered over pork-bone body | Rich, rounded, and complex | Marine lift that gives the pork broth definition |
Why seafood changes tonkotsu
A purely pork-based broth can be deeply satisfying, but its richness tends to dominate the palate. Seafood introduces a second register of flavor. Instead of adding simple heat or extra fat, it brings umami and aroma that can make the soup seem more expansive.
Marine ingredients can also create a sense of contrast. Pork broth is associated with warmth, density, and sweetness from prolonged cooking. Seafood can bring sharper savory edges and a lingering taste that recalls dashi-based Japanese cooking. The combination therefore connects ramen’s hearty character with Japan’s broader tradition of seafood-centered stock.
That relationship is especially important in a restaurant known for a rich gyokai-tonkotsu style. The goal is not to hide the pork or make the broth taste like a thin fish soup. It is to let both ingredients remain legible. A diner should be able to notice the full body of tonkotsu and the distinct umami of seafood within the same spoonful.
The blended approach can also make toppings feel more integrated. Sliced pork, vegetables, seaweed, seasoned egg, and noodles each meet a broth with enough concentration to hold their flavors. Rather than sitting beside the soup as separate components, they become part of one sustained taste.
A Sapporo expression of ramen
MEN-EIJI’s use of gyokai-tonkotsu fits Sapporo’s reputation as a city with a strong ramen culture and a taste for substantial, warming bowls. Sapporo ramen is often associated with bold flavor and satisfying richness, yet the city’s ramen scene is broad enough to support experimentation and refined interpretation.
MEN-EIJI Hiragishi BASE represents the brand’s Sapporo home, while Duck Ramen EIJI offers another expression within the same wider restaurant identity. The locations, menus, and concepts give visitors different ways to encounter the brand, but the attention to broth remains central to its reputation.
Founder Jun Furukawa’s career also places the restaurant in a wider professional context. His international pop-ups, collaborations, awards, and recognition including a Michelin Bib Gourmand show how a distinctly Sapporo-based ramen approach has reached audiences beyond Japan. The restaurant’s media coverage provides further context for the brand’s activities and recognition.
That history matters because gyokai-tonkotsu is more than a convenient label on a menu. It describes a culinary direction that MEN-EIJI has developed and presented across different settings. The broth connects local identity with a style that can be understood by ramen diners anywhere.
How to taste the balance
When approaching a gyokai-tonkotsu bowl, it helps to taste the broth before mixing in every topping. The first spoonful reveals its basic structure: how creamy or dense the pork base feels, how clearly the seafood comes through, and whether the seasoning emphasizes salt, soy, or another flavor.
Then try the soup with noodles. Noodles dilute and carry the broth, changing both its texture and its intensity. A rich soup should cling to them without becoming overwhelmingly heavy. Toppings offer another variation, especially ingredients that add freshness, smokiness, sweetness, or a contrasting chew.
A simple tasting order makes the difference between the two broth foundations easier to recognize:
Ways to read the bowl
- Taste the broth alone to identify its pork-bone body and seafood aroma.
- Eat a few strands of noodles with soup to judge how the broth coats and supports them.
- Try toppings separately before combining them with the broth.
- Return to the soup near the end, when the flavors have blended more fully.
The broth may also change slightly as it cools. Heat carries aroma upward at the beginning, while cooling can make saltiness, sweetness, and texture more apparent. Taking time with the bowl gives the gyokai-tonkotsu profile room to develop instead of reducing it to a single first impression.

Calling the soup gyokai-tonkotsu tells you precisely why MEN-EIJI ramen tastes so substantial and distinctive. The seafood component supplies marine umami and aromatic depth; the pork bones create the rich, rounded structure that gives the broth its signature weight. Neither side is incidental, and the name reflects their partnership.
For diners exploring Sapporo ramen, the phrase offers a useful guide to what awaits in the bowl. Visit MEN-EIJI Hiragishi BASE or Duck Ramen EIJI, review the current menu details through the restaurant’s official channels, and taste the broth slowly enough to find both foundations working together.
