Nagasaki, Kyushu — Shinchi Chinatown, founded by Fujian Chinese restaurateurs in Meiji era
Nagasaki champon is one of Japan's most distinctive regional noodles, created in the late Meiji era (c. 1899) by Chen Pingshun, a Chinese cook from Fujian Province who founded Shikairou restaurant in Nagasaki's Chinatown (Shinchi). The dish was designed as affordable, nutritious food for Chinese students, using pork bones and chicken to build a milky, robust broth, then loading it with a jumbled abundance of seafood (squid, shrimp, scallops, oysters, clams), pork, cabbage, bean sprouts, kamaboko, and woodear mushrooms — all stir-fried at very high heat before the broth is added. The noodle is a thick, round, alkaline champon-men made specifically for the dish, different from ramen or udon. A defining technique is that the toppings are cooked directly in the wok with lard and oyster sauce, the raw ingredients stir-fried together until caramelised, then the broth is added and the noodles cooked in the same vessel — everything absorbed together. Sara udon is Nagasaki champon's dry sibling: the same toppings are cooked as champon, but a starchy ankake sauce is poured over crispy-fried thin noodles (yakisoba-style noodles fried until crunchy) or alternatively thick champon noodles. The result is a study in textural contrast — the crispy noodles soften unevenly under the ankake, creating zones of crunch and chew.
Rich milky pork-chicken broth, abundant seafood sweetness, caramelised wok breath, the satisfying weight of a complete meal in one bowl
{"Stir-fry (炒め, itame) of all toppings in lard before adding broth is the foundational technique — high heat caramelisation is non-negotiable","Milky champon broth is built from pork bones (tonkotsu) and chicken together — lighter than Hakata tonkotsu but richer than clear chicken broth","Champon-men noodles are thicker and springier than ramen noodles — they are cooked in the broth, not separately","Sara udon crispy noodle variant requires deep-frying the noodles until fully crunchy before the ankake is ladled over","Oyster sauce and lard are the Fujian Chinese-origin flavour markers that distinguish champon from Japanese ramen"}
{"The best Nagasaki champon uses oyster, clam, and shrimp added at different times — oysters last (30 seconds) to prevent rubberiness","A tiny amount of sesame oil added at the finish brightens the broth without overwhelming the clean pork-chicken base","Authentic Shikairou-style includes only a small amount of togarashi on the side — champon is not a spicy dish; chilli is a diner's addition","Ankake sauce for sara udon should be thickened with potato starch, not katakuriko (now usually potato starch anyway) — thick enough to coat a spoon but not gloopy"}
{"Using ramen noodles instead of genuine champon-men — the champon noodle is formulated differently and behaves differently in broth","Undercooking the stir-fry before adding broth — the toppings must caramelise first; the Maillard crust is what makes champon distinct","For sara udon, allowing the fried noodles to sit too long before adding toppings — they absorb ambient moisture and lose their crunch"}
