Nakau Debuts a Summer Newcomer: Kin-Goma Chilled Beef Tsuke Udon
Nakau, the donburi and Kyoto-style udon chain operated by Nakau Co., Ltd. (President: Hiromasa Ikematsu; Head Office: Minato-ku, Tokyo), will release “Kin-Goma Hiyashi Gyuniku Tsuke Udon” (Golden Sesame Chilled Beef Dipping Udon) from 11:00 AM on Wednesday, August 5, 2026. Nakau is part of Zensho Holdings, the group behind Sukiya and other major restaurant brands.
The new Kin-Goma Chilled Beef Tsuke Udon and Kin-Goma Zaru Udon pair Nakau’s signature smooth, easy-to-slurp udon with a fragrant house-made golden sesame sauce. Compared with white sesame, golden sesame (kin-goma) is said to offer stronger aroma, richness, and umami. That deep sesame dipping sauce is finished with yuzu juice, giving it a refreshing citrus lift that keeps the richness from feeling heavy — an ideal match for hot summer days.
Topped with the Same Beef Used in the Popular Gyu-Suki Don
The udon is served with the beef used in Nakau’s popular Gyu-Suki Don. Simmered in a sweet-savory seasoning, the beef’s umami harmonizes with the bold golden sesame flavor, delivering layered richness in every bite. Chilled udon and sweet-savory beef is already a reliable pairing, and the added aroma of golden sesame and yuzu pushes this well beyond an ordinary bowl of cold noodles.
Prefer Classic Dashi? The Standard Chilled Beef Tsuke Udon Arrives Too
Launching alongside it is the Chilled Beef Tsuke Udon, served with Nakau’s original special zaru tsuyu dipping broth. Built on the deep flavor of dashi from bonito and kombu, the broth pairs beautifully with the umami of the beef. Diners can simply choose based on mood: the rich sesame sauce, or the clean, dashi-forward broth.
Customize It with Toppings
Additional toppings let you tune the flavor to taste:
- Taberu Rayu (crispy chili oil) — adds a gentle kick and extra depth
- Kodawari Tamago (premium egg) — makes the dipping sauce creamier and mellower
- Tororo (grated yam) — even smoother on the palate, great when summer heat kills your appetite
