"Chuka Soba Kotoihiso" Store Information

In Yamagata Prefecture, a ramen powerhouse, "Kotoihiso" is known as a legendary existence, only opening from October to the end of May. Although it was originally a ryokan (Japanese inn), the reason fans flock from all over the country seeking the unique bowl is the harmony of "noodles and broth" that allows for no compromise. The homemade medium-thick curly noodles are characterized by their refreshing texture, achieved through the ultra-high hydration dough kneaded daily by the owner, Mr. Kakegami, with keen focus. This is combined with a soup condensed with the rich umami of flying fish (ago), and finally, a deep aftertaste of soy sauce lingers.

What began as a challenge to support the inn during its off-season has spread by word-of-mouth for its deliciousness, becoming a shop with lines of up to 3 hours at its peak. It is a unique and legendary shop that continues to captivate people's hearts, often called "phantom ramen."
