A Sign That Summer Has Arrived in Japan
When summer arrives in Japan, you start seeing signs outside ramen shops that say “Hiyashi Chuka Hajimemashita,” meaning “Hiyashi Chuka is now available.” It’s one of those seasonal traditions that instantly tells everyone the hot weather has arrived. Despite the name, this refreshing dish isn’t have Chinese origins—it was created in Japan and has become one of the country’s most beloved summer meals.

Where the Name “Hiyashi Chuka” Comes From
The name literally means “chilled Chinese-style” in Japanese. “Hiyashi” means chilled, while “chuka” refers to Chinese-style cuisine. The dish is made with Chinese alkaline noodles (chuka noodles), which are the same type of noodles commonly used for ramen, but they’re served cold with a sweet and tangy hiyashi chuka sauce instead of hot broth. Depending on where you live, you may also hear people call it hiyashi ramen or chilled ramen.
A Refreshing Meal You Can Easily Make at Home
If you’ve been searching for an authentic hiyashi chuka recipe, you might be surprised by how simple it is to make at home. The sauce comes together in minutes, while the combination of silky egg, crisp cucumber, ham, and chilled noodles creates the perfect balance of flavors. Whether you call it hiyashi soba or simply a refreshing noodle salad, this colorful dish is perfect for hot summer days.
