Glossary of Japanese Soy Sauce Types

When we think of soy sauce, we often refer to “Koikuchi” or dark soy sauce, but Japanese law actually classifies soy sauce into five distinct categories, each defined by its manufacturing method and unique characteristics.

1. Koikuchi – Dark Soy Sauce

The most common type of soy sauce, accounting for about 84% of Japan’s soy sauce production. It has a rich flavor, combining saltiness, deep umami, mild sweetness, refreshing acidity, and a hint of bitterness. Versatile and used in both cooking and as a table condiment.

2. Usukuchi – Light Soy Sauce

Originating in the Kansai (Western East) region, this soy sauce is lighter in color and accounts for about 13% of production. It contains slightly more salt than Koikuchi to slow fermentation, resulting in a more subdued color and aroma.

Ideal for dishes where preserving the natural color of the ingredients is essential, such as simmered dishes.

3. Tamari – Tamari Soy Sauce

Mainly produced in the Chubu region, Tamari is a darker soy sauce known for its thick texture, rich umami flavor, and unique aroma.

Suitable for sushi, sashimi, and cooking dishes like teriyaki, where a beautiful red tint is desired. Also used in processed foods like rice crackers.

4. Saishikomi – Double-Brewed Soy Sauce

Originating in the Yanai region of Yamaguchi Prefecture, this soy sauce is brewed with previously made soy sauce instead of saltwater, hence the name “double-brewed.” It has an intense color, flavor, and aroma.

Mainly used as a dipping sauce for sashimi, sushi, and cold tofu.

5. Shiro – White Soy Sauce

Born in Aichi Prefecture, this soy sauce is even lighter than Usukuchi, with a pale amber color. It has a mild yet sweet taste and a distinctive aroma.

Utilized in clear soups, steamed dishes, and processed foods like rice crackers and pickles.

Additional Categories by Salt Content:

There’s also a classification based on salt concentration. Standard soy sauce has a salt content of 16-18%, but with the rise of health-conscious trends, many low-salt options are now available on the market.

  • 18% Salt: Usukuchi has slightly higher salt content than Koikuchi.
  • 16% Salt: Standard salt content for Koikuchi, Tamari, Saishikomi.
  • 12% Salt: Reduced salt soy sauces, including “Usushio” (light salt).
  • 9% Salt: Further reduced salt soy sauces, known as “Gensho” (low salt).
