Irodori Hiyashi Chuka
■ Mujinzou's Summer-Exclusive Chilled Noodles Are Back This Year!
"Niigata Ramen Mujinzou" will once again offer its popular summer-exclusive chilled noodles in 2026.
Starting sales on Thursday, May 7, are two items: the visually refreshing "Irodori Hiyashi Chuka" and the addictively spicy "Hiyashi Gyokai Tonkotsu Tsukemen." Each will be sold at its respective eligible stores.
The biggest feature is the "Kakishibu Noodles," an in-house made noodle kneaded with persimmon tannin from Sado's specialty "Okesa persimmon."
This manufacturing method is a patented technology first developed in Japan 20 years ago, and due to the properties of persimmon tannin, which contains polyphenols, it achieves a smooth texture and firm, chewy elasticity.
Especially in chilled dishes, this texture becomes even more pronounced, allowing you to fully savor the "deliciousness of the noodles themselves."
"Irodori Hiyashi Chuka (Soy Sauce)" (Tax included, 1,000 yen)
A colorful summer feast that brings coolness.
The secret homemade soy sauce tare thoroughly coats the homemade Kakishibu Noodles.
Generously topped with colorful vegetables and shredded egg omelet, it's a visually refreshing, light yet satisfying dish.
"Hiyashi Gyokai Tonkotsu Tsukemen" (Tax included, 1,000 yen)
A summer-exclusive stimulating dish using rich seafood pork bone broth x Niigata's special chili pepper "Onigoroshi."
Several types of dried bonito flakes scent the rich, chilled soup, with a "fiery sprinkle" of spice added. It's a "super spicy x rich" tsukemen that combines impact and umami to blow away the summer heat.
With 1.5 servings of noodles, it's a truly satisfying meal.
