Shoyu Ramen Tokyo Clear Soy Broth

Shoyu ramen (醤油ラーメン, soy sauce ramen) is Tokyo's defining ramen style — a clear, amber-coloured soup made primarily from chicken broth seasoned with a shoyu tare, served with curly, thin egg noodles in a precise aromatic composition. The Tokyo shoyu style is defined by restraint: the broth should be clear (not cloudy), the flavour layered but not overwhelming, and the noodles should retain their characteristic curly shape and slightly al dente bite. The original Rairaiken ramen shop opened in 1910 in Asakusa is often cited as the origin point; the chicken-shoyu combination became the Tokyo standard. The broth base is typically chicken bones, sometimes supplemented with pork trotters for body, simmered gently for 3-4 hours rather than the vigorous tonkotsu boil — maintaining clarity. The shoyu tare (醤油たれ) — soy sauce, mirin, sake, and sometimes dried fish sauce reductions — is added at service to season the base broth. A defining element of Tokyo shoyu ramen is the aromatic oil (香味油, kōmi-abura): chicken fat rendered with scallion and ginger and drizzled on the broth surface at service, creating a fragrant oil slick. Curly egg noodles (chijire men) made with kansui (alkaline salt solution) that creates the characteristic yellow colour and firm, springy texture are distinctively Tokyo. The composition is completed by thin slices of braised cha-shu, narutomaki (pink-and-white fishcake), bamboo shoots (menma), and nori.
