The highly popular "Hiyashi Ramen," which sold approximately 110,000 bowls in just 2.5 months last summer, has been further enhanced and improved this year! "Hiyashi Ramen" has been a popular summer "cold noodle" menu item since 2013, receiving rave reviews from customers every year.

Three Points of Evolution for the 2026 Summer "Hiyashi Ramen"

[Noodles] Exquisite mouthfeel and excellent firmness that complement the soup

We use "special thin noodles" uniquely developed to maximize compatibility with the soup. They offer a smooth, refreshing mouthfeel perfect for summer, combined with a firm, chewy texture.

[Soup] Double soup blending the umami of tonkotsu and the flavor of seafood

A double soup of tonkotsu and katsuobushi-flavored seafood is blended with a soy sauce tare made with iriko (dried anchovies). The moment it enters your mouth, the seafood flavor spreads, and a gentle sweetness emerges along with the rich tonkotsu umami.

[Harmony] Perfect unity for summer

The specially developed thin noodles and soup intertwine to create the ultimate flavor, mouthfeel, and texture that can only be enjoyed this summer.

This is a recommended base menu for those who want to first enjoy the special double soup, a harmonious blend of tonkotsu umami and katsuobushi/iriko flavors, in its simplest form. While rich, the aftertaste is surprisingly refreshing. The addition of a creamy, rich ajitama adds a mellow depth to the soup. This dish allows you to fully savor the mouthfeel of our uniquely developed thin noodles.

"Hiyashi Ramen Ajitama Oni-oroshi" \1,080

Refreshing with "Oni-oroshi," rich with "Ajitama." A cold dish to enjoy the balance!

Generously uses coarsely grated "oni-oroshi." Its refreshing juiciness makes it light and easy to eat until the end. Furthermore, the ajitama, characterized by its creamy yolk, harmonizes exquisitely with the dashi flavor, adding richness and mellowness. This dish combines different flavors into one.

"Hiyashi Ramen Butashabu" \1,060

Appetizing even on hot days. A cold dish finished with pork shabu-shabu.

The light umami of the refreshing pork shabu-shabu combines with the special double soup, which features a strong tonkotsu and katsuobushi flavor, creating a dish that is light yet satisfying. It's easy to eat even during seasons when appetite tends to decrease due to the heat.

"Hiyashi Ramen Butashabu Oni-oroshi" \1,160

Overwhelming satisfaction! A luxurious cold ramen with moist, exquisite pork shabu-shabu and oni-oroshi.

This year's new signature menu item! Refreshing pork shabu-shabu is generously paired with richly textured oni-oroshi. Despite its refreshing aftertaste, the juicy flavor of the pork makes it incredibly satisfying. This is a luxurious dish that will surely satisfy both your stomach and your heart this summer.

《5 Commitments of Ramen Zundouya》

[Commitment 1 Rich Tonkotsu Soup]

Ramen Zundouya's tonkotsu soup is simmered for over 10 hours in a special kiln using water and pork bones. By continuously boiling carefully prepared pork heads, backbones, and marubones over high heat until the bones break down, we achieve a rich, silky tonkotsu soup with no unpleasant odor.

[Commitment 2 Homemade Noodles]

Using special flour, our noodles offer the rich aroma and firmness of wheat. The thin, straight noodles with high hydration and strong firmness, and the medium-thick wavy noodles with moderate elasticity and good soup adhesion, are perfectly paired with our tonkotsu soup.

[Commitment 3 Store-Prepared Soft-Boiled Ajitama]

We boil fresh eggs in-store to a soft-boiled consistency and marinate them for a long time in our special sauce, creating ajitama with a rich yolk and a creamy texture.

[Commitment 4 Meltingly Delicious Chashu]

We use carefully selected pork with a good balance of lean meat and fat. The chashu, marinated in our special sauce, is melt-in-your-mouth tender and infused with flavor. Our proud chashu is meticulously prepared in its cut and searing.

[Commitment 5 Zundouya's Space]

The theme is "MATSURI" (festival), with the power of red and black and the warmth of wood. We cherish the lively atmosphere of a local Japanese festival within our stores. We hope you feel the excitement when you step inside and look around.
