Nagasaki Champon: One Wok, One Soup, Noodles Finished in the Broth
Pork and seafood go into the wok first, the vegetables follow, then a premixed soup comes to a boil and the separately boiled noodles finish in it. Keep that order, and keep the noodles, toppings and soup in the same pot at the end.
Pork, peeled shrimp, squid and clams hit a wok with a little oil and begin to change color. Carrot, cabbage, bean sprouts and shiitake follow for a brief toss, then a light soup of oyster sauce, chicken stock powder, sake, sugar, salt and water is poured in and brought to a boil. Last of all, noodles that were boiled in a separate pot go into that soup and simmer with everything else. That is Nagasaki champon (ちゃんぽん), a noodle soup from Nagasaki Prefecture in southwestern Japan.
This page follows a single two-serving recipe published by Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) in its "Uchi no Kyodo Ryori" (Our Regional Cooking) collection. Its amounts and order are kept as they are, without mixing in other versions. That recipe does not give cooking times, heat levels or temperatures, so this page does not add any. A few ingredient details are also left open in it; those are explained in the FAQ below rather than guessed. This recipe has not been kitchen-tested.
For other dishes from the same country, see our Japan page.
Ingredients: Serves 2
Cut the pork, seafood and vegetables into easy-to-eat pieces. Mix the soup ingredients together before you start cooking.
Choosing the Noodles and Other Ingredients
Look for noodles sold as Nagasaki champon noodles. Champon noodles are meant to be finished in the soup, as in this recipe. Ordinary ramen noodles and yakisoba noodles are not the same thing, and the thin, crisp fried noodles sold for sara udon belong to a different dish served with a thickened sauce. Swapping in any of these makes a different bowl from this recipe.
Check the package of your noodles for its own cooking directions, since products differ.
The kamaboko can be any ordinary Japanese fish cake. In Nagasaki, red-and-white kamaboko is a familiar champon topping, so use it if you find it; the amount stays at 30g.
The soup here is a simple mix of commercial chicken stock powder and seasonings. There is no bone broth to make, and no milk, lard or extra aromatics are added.
This dish contains shrimp, squid, clams and fish cake. Noodles, oyster sauce and stock powder can also contain wheat, soy and other allergens, so check the label of every product you use. Keep raw pork and seafood cold until cooking, and wash hands, boards and knives after handling them.
Equipment
- A pot and a colander for boiling and draining the noodles
- A wok, or a frying pan large enough to hold the toppings, soup and noodles together
- Measuring spoons and a measuring cup
- A small bowl for premixing the soup
- A knife and cutting board
Method: Noodles in Their Own Pot, Then Everything in One Soup
Mix the soup → boil and drain the noodles in a separate pot → stir-fry pork and seafood → lightly stir-fry the vegetables → add the soup and bring to a boil → add the noodles and simmer in the soup.
The kamaboko is added together with the vegetables so that every ingredient is used; that timing is our arrangement. Because the pork and seafood are stir-fried first, these steps assume they are uncooked.
The pork and seafood are cooked "until their color changes," but a change in color alone does not prove they are cooked all the way through. Make sure the pork and seafood are fully cooked before serving.
When Something Goes Wrong
| What happened | Likely cause | What to do |
|---|---|---|
| The noodles are thin and crisp, or turn soggy in the soup | Sara udon fried noodles were used | Use noodles sold as Nagasaki champon noodles |
| The soup tastes watery | Noodle-boiling water was added to the soup | Keep the 400ml soup water separate from the boiling water |
| The noodles were only boiled and served | The last step was skipped | Return the drained noodles to the soup and simmer them with the toppings |
| The pork still looks pink after stir-frying | Not cooked through yet | Keep cooking until fully cooked; don't rely on color change alone |
| The vegetables are limp before the soup goes in | Stir-fried too long in step 4 | Toss the vegetables only lightly before adding the soup |
| Kamaboko left on the board | It was forgotten | Add it with the vegetables in step 4 |
Variations Across Nagasaki: Seasons, Vegetables and Soups
The fixed recipe above stays as it is. The ideas below show how champon changes in Nagasaki; they are not swaps for the amounts in this recipe.
| Variation | What it looks like | How it relates to this recipe |
|---|---|---|
| Seasonal seafood | MAFF gives clams as a summer example and oysters as a winter one | This recipe keeps clams 80g; no oyster amount is given here |
| Red-and-white kamaboko | A familiar Nagasaki champon topping, according to MAFF | Use it as your kamaboko at the same 30g |
| Nagasaki traditional vegetables | Nagasaki City publishes a separate version with Tsujita Chinese cabbage and Nagasaki red turnip, plus lotus root, onion, shiitake and pork belly, using a prepared champon soup and boiled noodles | A different recipe with its own amounts and soup; don't mix it in |
| Base-kitchen champon | A Japan Maritime Self-Defense Force base in Omura publishes a version with chicken-bone stock and milk | A different broth and method; not added to this soup |
| Pork-bone versus chicken soups | MAFF describes a richer pork-bone Nagasaki champon and a lighter chicken-based Obama champon as two main styles in the prefecture | This recipe's chicken-stock-powder soup is one home formula, not a recreation of either style |
Background: A Nagasaki Everyday Dish with More Than One Story
MAFF describes champon as a family dish eaten every day in Nagasaki. According to the origin account it presents, Chin Heijun (陳平順), owner of the Chinese restaurant Shikairo in Nagasaki, created the dish in 1899 to give Chinese students something filling and affordable. This is the commonly told account of how it began, and is best read as that.
The name is not settled either. MAFF lists more than one theory, including one tracing it to a Chinese word (喰飯, read "shanpon") and another to a Portuguese word meaning "to mix." This page does not choose between them.
The ingredients are not fixed. MAFF names pork, kamaboko, vegetables, squid and shrimp as common, with seafood changing by season, and notes that ingredients vary. The soup varies too, from the pork-bone style to the lighter chicken-based champon of Obama.
On the noodles, MAFF's general description says champon noodles are simmered in the soup, while its two-serving recipe first boils them separately and then simmers them in the soup. This page follows the specific recipe, so it does both.
Champon is also distinct from sara udon, its Nagasaki neighbor. MAFF's sara udon page describes a thick-noodle form and a form made with thin, crisp fried noodles topped with a thickened sauce. So not every sara udon uses fried noodles, but neither form is a noodle soup finished in broth like champon.
Frequently Asked Questions
Can I use ordinary ramen or yakisoba noodles?
The MAFF recipe calls for store-bought Nagasaki champon noodles and does not offer ramen or yakisoba noodles as a substitute. Any swap is your own adjustment and will move the bowl away from this recipe. Thin fried sara udon noodles are meant for a different dish and are not a stand-in for soup noodles.
Do I really boil the noodles separately?
Yes. In this recipe the noodles are boiled in a separate pot, drained, and then simmered in the soup with the toppings at the end. The recipe gives no boiling or simmering time, and it does not say whether the noodles are fresh or pre-boiled. Use the package directions for your noodles as a guide.
Is champon the same as sara udon?
No. Champon is a noodle soup. Sara udon comes in a thick-noodle form and a thin, crisp fried-noodle form topped with a thickened sauce.
Should the pork and seafood be raw or precooked?
The MAFF recipe does not say. Because its method stir-fries the pork and seafood first, this page assumes uncooked ingredients; that is our reading, not something the recipe states. Cook them until the color changes and fully through, and don't treat color change alone as proof of safe cooking.
Does "clams 80g" include the shells?
The recipe lists "clams 80g" without saying whether that weight is shelled clam meat or clams in the shell. This page keeps it as 80g and does not decide either way.
When does the kamaboko go in?
The recipe lists 30g of kamaboko but its method only mentions "the remaining vegetables." This page adds the kamaboko together with the vegetables in step 4 so that it is used; that timing is an editorial arrangement.
Do I need pork-bone broth?
Not for this recipe. Its soup is oyster sauce, chicken stock powder, sake, sugar, salt and water. Pork-bone soups and the bone-stock-and-milk broth of the Omura base version are different recipes.
Are the ingredients fixed in Nagasaki?
No. Ingredients vary by household, shop and season. This page uses one fixed ingredient list and keeps the variations in their own section.
Can I store and reheat leftovers?
The recipe this page follows gives no storage or reheating guidance, so this page does not give storage times or reheating conditions.
