Soy Sauce for Japanese Washoku

Post:December 18, 2017   Updated:  

Soy sauce is one of common ingredients of Washoku.Soy sause

Process of Soy Sauce

The process begins with preparation of a batch of soybeans and wheat. These are made into a mash, with rice malt to cause fermentation, which is allowed to “set” for several days. Next, salt water is added and the mixture is permitted to “set” for a year. (In some other soy sauce-making processes, soy sauce is added at this stage instead of salt water=sweet tastes soy sause.)


There are 5 types.

  • Koikuchi soy sauce = dark colored soy sauce
    Generally soy sauce
  • Usukuchi soy sauce = light colored soy sauce
    More salty but color is light. It often used in West Japan. It’ s very useful when the color of ingredients is important.
  • Tamari soy sauce
    This sause is made from only soybeans, (if contains wheat, the percentage is less than 20%) . This is made in traditional process, it is very complicated, so we cannot get real tamari soy sauce easy …
  • Sai-shikomi soy sause = sweet tastes soy sause
    This soy sause is added soy sause insted of salt water. We use this on table in eating something like Sashimi or Sushi, not cooking.
  • Shiro soy sauce = White soy sauce
    Less colored than usukuchi soy sauce. Main ingredients are wheat.
