Koji facts for kids

Koji: A Key Ingredient and Name

The Amazing Koji Fungus

Koji is the common name for a type of mold called Aspergillus oryzae. This tiny fungus is super important in Japanese cooking. It's often called a "national mold" in Japan because it helps create so many traditional foods.

Koji mold grows on grains like rice, barley, or soybeans. When it grows, it produces special things called enzymes. These enzymes are like tiny tools that break down proteins, starches, and fats in the food. This process is called fermentation.

How Koji Makes Food Delicious

The enzymes from koji mold do amazing things. They turn starches into sugars, which is important for making sake (a Japanese rice wine). They also break down proteins into amino acids, which give foods a rich, savory taste known as umami.

Koji is used to make:

• Soy Sauce: Koji helps ferment soybeans and wheat to create this salty, savory sauce.
• Miso: This is a thick paste made from fermented soybeans, often used in soups.
• Sake: Koji helps turn rice into sugar, which then ferments into sake.
• Mirin: A sweet rice wine used in cooking.
• Rice Vinegar: Another fermented product that gets its start with koji.

Without koji, many of these classic Japanese flavors would not exist!

Koji in Japanese Time

In Japanese history, "Kōji" has also been used as the name for different eras or periods of time. An era name is like a special title given to a period of years, often linked to the reign of an emperor.

Understanding Japanese Eras

Japanese eras are different from how we usually count years (like 2024, 2025, etc.). Instead, they have names that change, usually when a new emperor comes to power or for other important reasons.

Two historical periods named Kōji include:

• Kōji (Heian period): This era lasted from 1142 to 1144. It was during the Heian period, a time when Japanese culture and art flourished.
• Kōji (Muromachi period): This era was much later, from 1555 to 1558. It happened during the Muromachi period, a time of civil wars and big changes in Japan.
