Shoyu and Vegan are two of the most talked-about styles of ramen, and if you have ever stared at a menu wondering which to order, you are not alone. Although both arrive as a steaming bowl of noodles in broth, they are genuinely different experiences — from the way the broth is built to the noodles, the seasoning and the toppings. This guide breaks down exactly what sets shoyu ramen and vegan ramen apart, where they overlap, and how to choose between them.
The short version: shoyu ramen is light to medium-bodied and savory, tangy and balanced with a clean soy backbone, while vegan ramen is light to medium-bodied and clean, earthy and surprisingly rich in umami. But the details are where it gets interesting.
Understanding Ramen Broth
Every bowl of ramen is really two things working together: a broth (the soup base, often simmered from bones, dashi or vegetables) and a tare (the concentrated seasoning that flavors it). It is easy to assume that names like "tonkotsu" and "miso" describe the same kind of thing, but they don't — some styles are named for the stock they are made from, and others are named for the seasoning that defines them.
That distinction is the key to understanding any ramen comparison. Shoyu ramen is defined by its seasoning (tare), while Vegan ramen is defined by its broth base. Keep that in mind and the differences below will make a lot more sense.
What is Shoyu ramen?
Shoyu ramen is the original — the bowl most food historians point to when ramen first took hold in Tokyo in the early twentieth century. The word shoyu means soy sauce, and that soy-based tare is what defines the style. Unlike tonkotsu, the defining feature here is the seasoning, not the stock, so the same shoyu tare can sit on top of a chicken, pork or seafood broth.
The classic shoyu broth is clear and brown, typically a light chicken stock rounded out with dashi made from kombu (kelp) and dried bonito. It is savory and aromatic with a gentle tang and a clean finish, letting the quality of the stock and the soy sauce shine rather than burying them under fat. It is the most "drinkable" of the foundational styles and a favorite of people who find tonkotsu too heavy.
Because it is balanced rather than intense, shoyu ramen is endlessly versatile and is the bowl most likely to feature picture-perfect, classic toppings: a slice of fish cake, a sheet of nori, bright green scallion and a jammy marinated egg arranged with care.
Seasoning. A soy-sauce tare is the heart of the style, frequently deepened with mirin, sake and a kombu-bonito dashi for layered umami.
Preparation. The stock is simmered gently to stay clear, then seasoned in the bowl with the soy tare — a much faster, cleaner process than the hard boil of tonkotsu.
Noodles. Medium-thickness noodles, often slightly curly or wavy, hold the lighter broth well without overwhelming it.
Toppings. Chashu, bamboo shoots (menma), nori, fish cake (naruto), a marinated egg and scallion are the textbook garnishes.
What is Vegan ramen?
Vegan ramen proves that you do not need pork bones or chicken to build a deeply savory bowl. Drawing on Japan’s tradition of shojin ryori (Buddhist temple cuisine), it leans on umami-rich plants — kombu (kelp), dried shiitake mushrooms and roasted vegetables — to create a stock with genuine depth.
The broth is then seasoned with a vegan tare, usually a soy (shoyu) or miso base, so vegan ramen can lean light and clear or hearty and earthy depending on the kitchen. Some shops blend in soy milk or nut milk to mimic the creamy body of tonkotsu, producing a "creamy vegan" bowl that is genuinely satisfying. The result is far more than a compromise — a well-made vegan ramen stands on its own next to any animal-based bowl.
Beyond being the obvious choice for plant-based diners, vegan ramen is a clean, vegetable-forward option that appeals to anyone looking for a lighter, mushroom-and-kelp-driven take on the dish.
Seasoning. A vegan shoyu or miso tare does the seasoning, with mushroom and kombu dashi supplying the umami that meat broths get from bones.
Preparation. Kombu and shiitake are steeped, vegetables are often roasted for depth, and soy milk is sometimes added for a creamy, tonkotsu-like body.
Noodles. Medium noodles are standard — just check that they are egg-free, as many ramen noodles contain egg.
Toppings. Tofu, sautéed or marinated mushrooms, corn, leafy greens, bamboo shoots and nori replace the usual meat and egg.
Shoyu vs. Vegan ramen: the key differences
Here is how the two styles stack up side by side, from the broth base all the way to the bowl in front of you.
| Attribute | Shoyu Ramen | Vegan Ramen |
|---|---|---|
| Broth base | a clear chicken stock, often blended with dashi (kombu and bonito) and sometimes pork | kombu, dried shiitake and roasted vegetables, sometimes enriched with soy milk |
| Defining seasoning (tare) | a soy-sauce-based tare, which is what defines the style | a vegan shoyu or miso tare for seasoning |
| Flavor profile | savory, tangy and balanced with a clean soy backbone | clean, earthy and surprisingly rich in umami |
| Body | light to medium-bodied | light to medium-bodied |
| Appearance | clear amber-brown | clear amber, or tan when miso-based |
| Richness (1–5) | 2 / 5 | 2 / 5 |
| Typical noodles | Medium-thickness noodles, often slightly curly or wavy, hold the lighter broth well without overwhelming it. | Medium noodles are standard — just check that they are egg-free, as many ramen noodles contain egg. |
| Origin | Tokyo, where the first bowls of ramen in Japan were served in the early 1900s | a modern, plant-based evolution rooted in Japan’s shojin (Buddhist temple) cooking |
Broth and body. The biggest difference you will notice is weight. Shoyu ramen is light to medium-bodied (light), built from a clear chicken stock, often blended with dashi (kombu and bonito) and sometimes pork, while vegan ramen is light to medium-bodied (light), built from kombu, dried shiitake and roasted vegetables, sometimes enriched with soy milk. The two are closer in richness than many pairings, so the contrast is more about flavor character than sheer heaviness.
Seasoning. Shoyu gets its character from a soy-sauce-based tare, which is what defines the style, whereas Vegan relies on a vegan shoyu or miso tare for seasoning. This is why the two taste distinct even when the underlying stock is similar — the tare steers the whole bowl.
Noodles and toppings. The styles even differ down to the strands. Shoyu typically comes with: medium-thickness noodles, often slightly curly or wavy, hold the lighter broth well without overwhelming it. Vegan leans toward: medium noodles are standard — just check that they are egg-free, as many ramen noodles contain egg. Toppings follow suit, with shoyu favoring chashu, bamboo shoots (menma), nori, fish cake (naruto), a marinated egg and scallion are the textbook garnishes. and vegan favoring tofu, sautéed or marinated mushrooms, corn, leafy greens, bamboo shoots and nori replace the usual meat and egg.
What Shoyu and Vegan ramen have in common
For all their differences, these two share the same DNA. Both are authentic, time-honored bowls of ramen built on the same fundamental structure — a savory broth, a seasoning tare, springy wheat noodles and a thoughtful set of toppings. Both deliver the deep umami satisfaction that makes ramen so crave-worthy, and both are traditionally finished with familiar garnishes like chashu pork, scallions and a marinated egg.
Both are also best eaten immediately, while the noodles are still firm and the broth is piping hot, and both reward a good slurp — pulling air across the noodles cools them and amplifies the aroma. Whichever you choose, you are getting a genuine bowl of ramen; the question is simply which flavor and weight you are in the mood for.
Shoyu or Vegan: which should you order?
It comes down to how rich and bold you want your bowl. Choose shoyu ramen when you want the more intense, filling experience — it is people who want a balanced, savory, soup-forward bowl that is satisfying without being heavy. Choose vegan ramen when you are after a light bowl — it is plant-based diners and anyone wanting a lighter, vegetable- and mushroom-driven bowl with real umami.
Weather and appetite matter too. On a cold day or when you are truly hungry, the richer shoyu bowl hits hardest. When you want something you can finish without feeling weighed down, vegan is the smarter pick. And honestly? The best way to settle the shoyu-versus-vegan debate is to try both. Most ramen lovers keep both in rotation and order by mood.

Frequently asked questions
What is the main difference between shoyu and vegan ramen?
The core difference is the broth. Shoyu ramen is built on a clear chicken stock, often blended with dashi (kombu and bonito) and sometimes pork and is light to medium-bodied with a savory, tangy and balanced with a clean soy backbone character, while Vegan ramen is built on kombu, dried shiitake and roasted vegetables, sometimes enriched with soy milk and is light to medium-bodied with a clean, earthy and surprisingly rich in umami character. In short, shoyu is the richer, more intense bowl and vegan is the lighter one.
Which is richer, shoyu or vegan ramen?
Shoyu ramen is the richer of the two — it is light compared with vegan, which is light. If you want the more filling, intense bowl, go with shoyu; if you want something cleaner and lighter, choose vegan.
Do shoyu and vegan ramen use the same noodles?
Not necessarily. Shoyu: Medium-thickness noodles, often slightly curly or wavy, hold the lighter broth well without overwhelming it. Vegan: Medium noodles are standard — just check that they are egg-free, as many ramen noodles contain egg. As a rule, richer and miso-style broths pair with thicker, chewier noodles, while lighter, clearer broths pair with thinner ones.
Which should a first-timer try, shoyu or vegan?
If you are new to ramen and want the boldest, most crowd-pleasing introduction, start with shoyu. If you prefer to ease in with something more balanced and broth-forward, vegan is the gentler entry point. Both are worth ordering — many fans rotate between them depending on their mood and the weather.
