Ramen is a Japanese dish. It consists of Chinese-style wheat noodles served in a meat or (occasionally) fish-based broth, often flavored with soy sauce or miso, and uses toppings such as sliced pork (チャーシュー chāshū), dried seaweed (海苔 nori), menma (メンマ), and green onions (葱 negi). Nearly every region in Japan has its own variation of ramen, from the tonkotsu (pork bone broth) ramen of Kyushu to the miso ramen of Hokkaido
By 1900, restaurants serving Chinese cuisine from Canton and Shanghai offered a simple ramen dish of noodles (cut rather than hand-pulled), a few toppings, and a broth flavored with salt and pork bones. Many Chinese living in Japan also pulled portable food stalls, selling ramen and gyōza dumplings to workers. By the mid-1900s, these stalls used a type of a musical horn called a charumera (チャルメラ, from the Portuguese charamela) to advertise their presence, a practice some vendors still retain via a loudspeaker and a looped recording. By the early Shōwa period, ramen had become a popular dish when eating out.
