The origins of ramen can be traced back to Yokohama Chinatown in the early 20th century. The word "ramen" is a Japanese borrowing of the Chinese word lamian (拉麵), meaning "pulled noodles", but is not derived from the northern Chinese dish of lamian. Instead, the dish evolved from southern Chinese noodle dishes from regions such as Guangzhou, reflecting the demographics of Chinese settlers in Yokohama. Ramen gained popularity in Japan, especially during food shortages following World War II. In 1958, instant noodles were invented by Momofuku Ando, further popularizing the dish.
