Complete Guide to Sanma Ramen | Comprehensive Explanation of the History, Characteristics, and Famous Restaurants of Kanagawa Prefecture’s Local Cuisine
Sanma ramen, loved as the soul food of Kanagawa Prefecture residents, continues to be cherished. While it may be unfamiliar to people outside the prefecture, it is a local dish widely enjoyed throughout Kanagawa Prefecture, centered in Yokohama. This article thoroughly explains the charm of this unique ramen, from its history and characteristics to recommended famous restaurants.
What is Sanma Ramen? Basic Knowledge of Kanagawa Prefecture’s Signature Local Cuisine
Sanma ramen is a ramen dish made with soy sauce-based soup and thin noodles, finished with stir-fried vegetables centered on bean sprouts topped with a thickened gravy sauce. While it may appear to be ordinary gravy ramen at first glance, it has firmly established its position as a local dish that developed uniquely in Kanagawa Prefecture, particularly in Yokohama City.
Basic Components of Sanma Ramen
The basic components of sanma ramen are as follows:
- Soup: Soy sauce-based Chinese soup is common
- Noodles: Thin straight noodles are the mainstream
- Toppings: Stir-fried vegetables such as bean sprouts, pork, cabbage, and Chinese chives
- Gravy: Thickened sauce made with cornstarch is the characteristic
The piping hot gravy sauce envelops the noodles and soup, keeping them warm until the end, which is a major appeal of sanma ramen. Despite being packed with vegetables and hearty in volume, it has a surprisingly light taste that is easy to eat.
History of Sanma Ramen and the Origin of Its Name
Birth in Yokohama Chinatown
While there are various theories about the origin of sanma ramen, the most widely accepted theory is its birth in Yokohama Chinatown in the early Showa period. The origin is widely attributed to either the Chinese restaurant “Heichinro” or “Gyokussentei.”
It is believed that stir-fried vegetables originally made as staff meals were placed on top of ramen, which gradually became established as a menu item and spread to Chinese restaurants and ramen shops throughout Yokohama City.
The Origin of the Name “Sanma”
There are several theories about the origin of the name “Sanma”:
- “Raw Horse Noodles” Theory: The theory that it derives from “Sengma Noodles (Sanma Min)” in Cantonese, a noodle dish with toppings added later. “Sengma” means “placing fresh toppings on top.”
- “Three Codes” Theory: The theory that it was called “Three Codes” because three types of ingredients (bean sprouts, pork, and other vegetables) are used.
- “Sanma” Phonetic Theory: The theory that it was simply named “Sanma” for its pleasant sound and easy memorability.
Currently, the “Raw Horse Noodles” theory is considered most plausible, and is supported by many experts and researchers.
Spread Throughout Kanagawa Prefecture
After World War II, as sanma ramen became a standard menu item in town Chinese restaurants and casual Chinese food establishments throughout Yokohama City, it gradually spread to cities throughout Kanagawa Prefecture including Kawasaki, Sagamihara, and Yokosuka.
Particularly from the 1960s through the 1980s, sanma ramen became completely rooted in Kanagawa residents’ daily lives, with the dish even appearing in school lunches in some areas, becoming a beloved local cuisine of Kanagawa Prefecture.
Characteristics and Appeal of Sanma Ramen
Vegetable-Rich and Healthy
The greatest characteristic of sanma ramen is the abundant use of vegetables. Centered on bean sprouts, with the addition of cabbage, Chinese chives, onions, carrots, and many other types of vegetables that are stir-fried as toppings.
A single bowl of sanma ramen typically contains two to three times more vegetables than regular ramen, offering excellent nutritional balance. The fact that it is healthy despite being ramen is one reason it has been loved for many years.
Long-Lasting Heat from the Thickened Gravy
The thickened gravy serves not just visual impact but practical function as well. By covering the noodles and soup, the gravy prevents heat from escaping, allowing you to eat the dish piping hot until the very end.
Whether in winter or during summer with air conditioning, it is cherished as a bowl that warms the body.
Simple Yet Deep Flavor
The seasoning of sanma ramen is fundamentally simple. The soy sauce-based soup is combined with the natural sweetness of vegetables and the umami of pork, with the gravy’s thickness bringing everything together.
While not flashy, it features an unpretentious flavor that doesn’t grow tiring, with universal appeal to people of all ages. Each restaurant differs in the types of vegetables used, cooking method, and gravy thickness, allowing you to enjoy each establishment’s individuality.

While sanma ramen is Kanagawa’s local dish, in recent years more restaurants throughout Tokyo and other regions have begun serving it. However, it is not as common as in Kanagawa Prefecture and typically limited to specialty shops or restaurants run by Kanagawa natives.
Can “True” Sanma Ramen Only Be Eaten in Chinatown?
