In an exciting culinary evolution, Myojo Foods Co., Ltd., led by President Akihiro Toyodome, is set to launch a brand new cup yakisoba product on October 13, 2025: "Myojo Chuka Saimai Cup Eirin Su-Lai Yakisoba." This marks the debut of a new dry noodle menu within the popular "Chuka Saimai" line, renowned for its high-quality flavors since its inception back in 1981. Known for its authentic taste and enduring popularity, the line has captivated noodle enthusiasts with its rich history.
What makes the new Spicy Sour Yakisoba particularly exciting is its innovative use of sour soup flavors combined with stir-fried noodles, a first for this series. It features an intense sauce that blends the alluring tastes of fragrant black vinegar and spicy chili oil, creating a delightful treat for those who crave unique flavors. The combination doesn't stop there: the sauce is further developed by infusing elements of dark soy sauce and Chinese soy sauce, complemented by chicken, char siu, and oyster essence, yielding a complex soy dressing. Sesame oil adds a delightful fragrance, while the sharpness of chili oil brings the heat.
For its components, this dish showcases classic ingredients you’d expect in sour soup—bok choy, imitation crab, and shiitake mushrooms—elevating this noodle dish to a special gastronomical experience.
Hailing from the iconic Eirin restaurant, based in Kagurazaka, Tokyo, operators have been delivering quality Chinese food since 1956, garnering a reputation for using only the finest ingredients. Eirin's celebrated Su-Lai Tanmen (Spicy Sour Soup Noodle) has a notable backstory; it originated from a dish created by the head chef as a personal meal, which was eventually introduced to customers and became a house specialty.
This new yakisoba encapsulates the essence of Eirin’s tradition while pushing the envelope with a modern twist, making it a perfect addition to the changing palette of the fall season. Interested consumers can anticipate this innovative dish to satisfy both their taste buds and appetite starting this fall.
The Myojo Chuka Saimai Cup Eirin Spicy Sour Yakisoba packs 117g of flavor packed goodness (85g of noodles) and is set to retail for 298 yen (excluding tax). Each case comprises 12 units, ensuring that fans won’t run out anytime soon.
