Curry Udon (カレーうどん)

Picture the smell of Japanese curry rising from a steaming bowl of noodles. That is curry udon (カレーうどん): chewy wheat noodles in a hot, curry-seasoned broth. It is not curry rice poured over noodles, though. Instead, cooks season noodle-shop dashi with curry, then thicken it so it clings to every strand.

Here is how curry udon developed in Japan, what it tastes like and how it compares with regular udon. You will also find a home recipe built on dashi and curry powder, a few popular variations and three specialist shops to try.

What Is Curry Udon?

Curry udon is a Japanese noodle soup of thick udon in a curry-flavored dashi broth. Dashi is Japan’s basic soup stock, usually made from bonito flakes and kombu seaweed. From there, cooks season it with soy sauce and curry, add meat, leek and fried tofu, and thicken it with potato starch. In short, it sits halfway between a bowl of udon and a plate of Japanese curry.

Why does the dashi matter so much? In comparison, Japanese curry rice uses a thick, stew-like sauce. Curry udon, by contrast, starts from the light, savory stock used at noodle shops, so the bowl tastes more like soup than stew. For the noodles themselves, see our guide to types of Japanese udon.

What Does Curry Udon Taste Like?

Curry udon tastes savory, mildly spicy and deeply warming. First, the dashi brings smoky, seafood-based umami, while soy sauce and mirin add salt and a little sweetness. Curry spice sits on top of that base rather than taking over. As a result, the thick broth makes every bite feel richer than regular udon.

Texture is half the appeal, too. In particular, the thick, glossy broth coats the soft, chewy noodles, so each bite carries curry with it. Fair warning, though: that same broth loves to splash, so a white shirt is a real gamble.

So, is curry udon spicy? Usually it is mild to moderately spicy. However, specialist shops may offer hotter versions, and some add milk, coconut or fruit for a rounder, sweeter taste.

Curry Udon Ingredients and Toppings

In general, a classic bowl needs four building blocks: udon, dashi, curry seasoning and a thickener. Everything else, in other words, is a topping.

Curry powder and curry roux behave differently, so recipes rarely swap them gram for gram. After all, roux already contains fat, flour and seasoning, while powder gives a sharper spice that you thicken yourself. Our Japanese curry guide explains the wider family of curry dishes.

• Japanese leek (naganegi): sliced on the diagonal; it softens into the broth.
• Pork, beef or chicken: thin slices cook quickly in the simmering soup.
• Aburaage: thin fried tofu that soaks up the curry dashi like a sponge.
• Kamaboko: a firm, savory fish cake with a mild seafood flavor; often optional.
• Egg, tempura crumbs or cheese: popular extras at some shops and at home.

By contrast, pickles such as fukujinzuke appear more often with curry rice. Still, some shops serve them on the side, and Toyohashi’s local style lists pickles like these in its official rules.

History of Curry Udon

Curry udon is generally traced to the late Meiji era, in the early 1900s, when curry was catching on in Japan. At the time, soba and udon shops are said to have begun adding curry, a Western-influenced dish already adapted to Japanese tastes, to their own dashi. However, several restaurants claim a link to its creation, and no source has verified a single origin.

The Waseda Story: Sanchōan

One well-known story points to Sanchōan (三朝庵), a soba restaurant near Waseda University in Tokyo. According to Waseda University, the shop opened in 1906. It is also regarded as a birthplace of egg-bound katsudon and curry nanban, the curry noodle dish behind curry udon. Note the wording, though: the university presents this as a tradition, not settled fact. Sadly, Sanchōan closed on July 31, 2018.

The Asamatsuan Lineage

Meanwhile, a second account centers on Asamatsuan (朝松庵), a soba shop in Nakameguro, Tokyo. The Curry Udon 100 Year Innovation Project (カレーうどん100年革新プロジェクト) credits its second-generation owner, Torinosuke Tsunoda, with spreading curry nanban, including curry udon, across Japan.

Since then, the dish has kept changing, from fiery bowls to mild, creamy ones. Even so, the idea behind them stays the same: curry, carried by dashi.

Curry Udon Day: August 2

The Curry Udon 100 Year Innovation Project designated August 2 as Curry Udon Day. According to the project, curry udon is widely known but eaten less often than you might expect. So the day aims to create more chances to eat it and to encourage new curry udon ideas. The food trade paper Nihon Shokuryo Shimbun explains the choice. It combines June 2, formerly Yokohama’s Curry Memorial Day, with July 2, Udon Day.

Don’t mix it up with Curry Nanban Day on December 1. The same project chose that date to honor Torinosuke Tsunoda of Asamatsuan, whose birthday it was.

Curry Udon, Curry Soba and Curry Nanban

Essentially, curry udon and curry soba use the same curry dashi, just with different noodles. Because soba is thinner and made with buckwheat, curry soba feels lighter. Curry nanban, however, is the tricky one.

Dish	Base	Texture	Flavor
Curry udon	Curry dashi with thick wheat noodles	Thick broth, chewy noodles	Savory, mildly spicy
Curry soba	Curry dashi with buckwheat noodles	Lighter, thinner noodles	Earthier from the buckwheat
Curry rice	Curry sauce over rice	Stew-like	Richer, sweeter

Kodansha’s food dictionary defines curry nanban as curry soba or curry udon with green onion added. Some versions use regular onion instead. In other words, it does not always mean soba. Menus use the term in slightly different ways, so check the description if you have a preference.

Popular Curry Udon Variations

Overall, curry udon adapts easily, and new regional and home versions keep appearing. Here are four styles worth knowing.

Toyohashi Curry Udon

Toyohashi curry udon is a local specialty from Toyohashi, a city in eastern Aichi Prefecture in central Japan, created in 2010. Specifically, shops layer rice, grated yam (tororo) and curry udon in one bowl, from the bottom up. Its five rules also call for homemade noodles and Toyohashi quail eggs. After the noodles, you mix the leftover curry with the rice and yam, almost like a porridge.

Chicken and Green Onion Curry Udon

For example, this easy home version usually starts from store-bought curry roux. Because chicken breast stays mild, it lets the curry stock shine. Also, slice the green onion diagonally for a little extra bite and color.

Soy Milk Curry Udon

Here, soy milk and curry powder make a paler, creamier broth. Many home cooks season it with mentsuyu, a bottled noodle-soup concentrate, which saves making dashi from scratch. The result tastes gentle and rich, and pork adds a savory finish.

Curry Stew Udon

Curry stew udon comes to the table in a clay pot, with a thicker broth and heartier toppings. Inside, chicken thighs and fried tofu give it a deeper savory flavor. It suits cold weather best, honestly.

Have leftover Japanese curry at home? It makes quick curry udon too. First, thin the curry with dashi or water until it flows easily. Then add a dash of soy sauce. For a brothier, spice-forward cousin from Hokkaido, see soup curry.

When and Where Do Japanese People Eat Curry Udon?

In general, curry udon is everyday food, available all year rather than tied to a season. However, its thick broth holds heat longer than thin udon soup, which makes it especially welcome on cold days. In practice, you will see it at three kinds of places.

• Neighborhood soba and udon shops: many list curry udon or curry nanban next to their regular bowls.
• Curry udon specialists: shops such as Senkichi or ZEYO. focus on it entirely, with their own spice blends.
• Home kitchens: turning leftover curry into curry udon is a familiar trick, and packaged roux makes it easy.

Can you drink the broth? That is up to you, as with any Japanese noodle soup, and leaving some behind is perfectly fine.

Curry Udon vs Regular Udon

The main difference is the broth. Regular hot udon swims in a clear, soy-and-dashi soup, while curry udon uses a thick curry dashi. As a result, the two feel very different to eat, even with the same noodles.

Feature	Curry udon	Regular hot udon
Broth	Curry-flavored dashi	Clear dashi with soy sauce
Thickness	Thick and glossy	Thin, soup-like
Seasoning	Curry powder or roux, soy sauce, mirin	Soy sauce, mirin, salt
Common toppings	Meat, leek, fried tofu	Green onion, tempura, kamaboko, nori
Flavor	Savory, mildly spicy	Light, umami-forward
Best season	Any time; especially warming on cold days	Year-round; cold versions in summer

Curry Udon Recipe

To begin with, this curry udon recipe builds the broth from dashi and curry powder rather than store-bought roux. That keeps the flavor closer to a noodle-shop bowl. In short, you stir-fry the toppings and simmer them in seasoned curry dashi. Then you thicken the soup and pour it over hot udon.

Ingredient notes: “Boiled udon” means pre-cooked udon. Frozen or fresh udon also work if you cook them as the package directs. Usukuchi (light-colored) soy sauce keeps the broth brighter, but regular soy sauce is fine. Kamaboko is optional.

Curry Udon Ingredients for Two

How to Make Curry Udon: Toppings and Broth

1. Prepare. Make a strong dashi (you need 600 ml); this recipe uses 40 g of dried bonito flakes per liter of water. Alternatively, mix 20 g of thick-shaved bonito with 20 g of other flakes such as mackerel. Then cut the leek, kamaboko, fried tofu and pork into bite-size pieces.
2. Cook the toppings. Heat the oil in a medium saucepan and stir-fry the leek and pork. Just before they finish cooking, add a pinch of salt.
3. Add the curry. Next, sprinkle the curry powder and flour over the pork and leek. Stir for a moment, until no dry powder remains.
4. Season the broth. Pour in the dashi a little at a time, stirring to avoid lumps. Then add the soy sauce, mirin, sugar, fried tofu and kamaboko. Bring to a boil, lower the heat slightly, skim off any scum and simmer for 1 to 2 minutes.

How to Make Curry Udon: Thickening and Serving

5. Thicken. First, stir the potato starch into the 60 ml of water. Because starch sinks fast, stir it again just before using. Turn the heat to low and pour the slurry in gradually, stirring from the bottom so the soup thickens evenly. Once thick, keep it bubbling gently for 1 to 2 minutes so the broth cooks through and the texture settles.
6. Heat the noodles and serve. Warm the udon, then drain it well in a colander; extra water thins the soup as you eat. Finally, place the noodles in bowls, ladle the curry broth over the top and serve right away.

Fixing the texture: If the broth turns too thick, loosen it with a splash of dashi. If it stays thin, add a little more starch slurry, again stirring as you pour.

Vegetarian, Gluten-Free and Allergen Notes

For vegetarian curry udon, use kombu and shiitake dashi, skip the pork and kamaboko, and add mushrooms with the fried tofu. Check curry roux labels, too, since some contain meat extract or dairy. Some Japanese brands sell roux made without animal ingredients, but those may still contain wheat.

For a gluten-free bowl, you would need gluten-free noodles and tamari instead of soy sauce. Also use potato starch in place of the flour. As written, this recipe contains wheat, soy, fish (from the dashi and kamaboko) and pork. Always check each package, because formulas vary by brand.

Where to Eat Curry Udon in Japan

In general, you can order curry udon at many udon and soba shops across Japan. For a deeper dive, though, look for a curry udon specialist. These three shops sit in Tokyo, in Mie Prefecture in central Japan and in Ibaraki Prefecture northeast of Tokyo. They are examples rather than a ranking.

Check before visiting: We reviewed these details on October 26, 2026. Hours, menus and prices change, so confirm with each shop before you go. Photos are from our archive and may not match current menus.

Senkichi (千吉), Jiyugaoka, Tokyo

For a start, Senkichi is a curry udon specialist chain, and its Jiyugaoka branch keeps long hours. Our archive photo shows a set with rice, salad and chikuwa tempura on the side. However, menu names change, so check the current lineup on the official site.

Tamaki (たま樹), Matsusaka, Mie

Next, Tamaki is a curry udon specialist near Tokuwa Station in Matsusaka, a city in Mie Prefecture. It opens for lunch only, and we could not find an official website. Therefore, call ahead before making a special trip.

ZEYO. (カレーうどん ZEYO.), Tsukuba, Ibaraki

ZEYO. calls itself Ibaraki’s only curry udon specialist. For its dashi, it uses several premium dried fish, including bonito, mackerel and sardines, seasoned with soy sauce and hon-mirin. The shop then blends in 28 spices and spends two days making the curry soup. In our archive photo, thick slices of pork sit on top.

Why Curry Udon Remains a Japanese Comfort Food

Ultimately, curry udon works because of three simple parts: savory dashi, chewy udon and mild curry spice. It began as a Meiji-era experiment at noodle shops and still turns up everywhere from specialist counters to home kitchens.

Curry Udon FAQ

About the Dish

Is curry udon spicy?

Usually, curry udon is mild to moderately spicy. The type and amount of curry powder or roux set the heat, so a home version is easy to adjust. Also, specialist shops sometimes offer hotter bowls.

Is curry udon the same as curry poured over noodles?

Not quite. Classic curry udon starts from dashi, the savory stock used for noodle soups, seasoned with soy sauce and curry. The broth is thinner and soupier than curry-rice sauce. Leftover curry can still make a quick version, if you thin it with dashi.

What is the difference between curry udon and curry nanban?

Curry nanban usually means curry soba or curry udon with green onion added. Some shops use regular onion instead. Because the term can cover either noodle, check the menu description.

Cooking at Home

What type of udon works best?

Frozen udon works well because it stays chewy and heats quickly. Pre-boiled udon, on the other hand, is the softest and most convenient. Dried udon works too, but it takes longer to cook. Whichever you use, drain it well so it does not water down the broth.

How do I keep curry broth from becoming lumpy?

Stir the potato starch slurry again just before you add it, because the starch settles fast. Then lower the heat and pour it in slowly while stirring from the bottom. Adding the dashi gradually after the flour also helps prevent lumps.

Can I make curry udon with store-bought curry roux?

Yes. Many home versions, like the chicken and green onion style above, start from roux. Then dissolve it in dashi rather than plain water for a noodle-shop taste. Because roux already contains flour, you may need little or no extra thickener.

Can curry udon be vegetarian or vegan?

At home, yes, with changes. Use kombu and shiitake dashi instead of bonito, skip the meat and fish cake, and check the roux label for meat extract or dairy. At restaurants in Japan, though, assume the broth contains bonito dashi unless the shop says otherwise.
