Which alternate Japanese name for ramen means 'Chinese soba'?

The alternate Japanese name for ramen meaning “Chinese soba” is Chūka soba.

The term combines chūka, meaning Chinese-style, with soba, a Japanese word that can refer broadly to noodles—not only buckwheat noodles. Chūka soba therefore distinguishes ramen-style wheat noodles from traditional Japanese soba.

Ramen developed in Japan from Chinese-influenced noodle soups, especially those served in Chinese communities such as Yokohama Chinatown. “Chūka soba” became a common replacement for shina soba after the latter acquired derogatory associations in the postwar period.

Ramen is now the dominant name nationwide, but chūka soba remains common in places such as Takayama and can suggest a more classic style. Kake soba and zaru soba are buckwheat-noodle dishes, while yakisoba is a stir-fried wheat-noodle dish rather than a synonym for ramen.
