Japanese Chinese cuisine, also known as chūka, represents a unique fusion of Japanese and Chinese culinary traditions that have evolved over the late 19th century and more recent times. This style, served predominantly by Chinese restaurants in Japan, stands distinct from the "authentic Chinese food" found in areas such as Yokohama Chinatown. Despite this difference, the cuisine retains strong influences from various Chinese culinary styles, as seen in the shippoku cooking style.
A significant number of these dishes were introduced to Japan either by Chinese immigrants or Japanese soldiers returning from the invasion and colonization of China, creating a unique gastronomic landscape that reinterprets Chinese cuisine through a Japanese lens. This style of cuisine has found its expression in three main types of restaurants: ramen restaurants, dim sum houses, and standard Chinese-style restaurants. The resulting adaptations span various regional Chinese cooking styles and techniques, from Sichuan's spicy stir-fries to Zhejiang's slow-cooked stews, contributing to the rich and diverse character of chūka.
