Description
Miyako Koji Powder is a finely milled Japanese rice koji made by Ise Sou, a producer of traditional fermentation ingredients. Using a specialized milling process, the company transforms its traditional Miyako Koji into a smooth powder while preserving the enzyme activity that makes koji useful in Japanese cooking and fermentation.
Made from Japanese-grown rice, this convenient powdered form blends easily into liquids, seasonings, and other preparations. It is particularly useful for making smooth shio koji, amazake, and marinades without the grainy texture of conventional dried rice koji.

What Is Rice Koji?
Rice koji (米麹) is made by cultivating koji mould on steamed rice. During cultivation, the mould produces enzymes that help break down starches into sugars and proteins into smaller components, including amino acids. These enzymatic reactions contribute natural sweetness, savoury depth, and texture changes in a variety of preparations.
Koji is a fundamental ingredient in Japanese food culture, traditionally used to make miso, amazake, shio koji, shoyu koji, and other fermented foods and seasonings.
Why Powdered Koji?
Conventional dried rice koji retains the shape of rice grains, which may require breaking apart or softening before use. Miyako Koji Powder is finely milled using a specialized process that maintains its enzyme activity, allowing it to disperse more evenly into liquids and mixtures.
The fine texture makes it especially useful for producing smoother fermented seasonings and beverages. Its powdered form also makes it convenient to incorporate koji into cooking, baking, and recipe development.
Culinary Applications
- Shio koji: Prepare a smooth fermented seasoning for marinades, sauces, and everyday cooking.
- Amazake: Make a traditional naturally sweet rice drink with a finer consistency.
- Shoyu koji: Combine with soy sauce to prepare a savoury fermented condiment.
- Koji marinades: Use in marinades for meat, fish, and vegetables to develop flavour and help modify texture.
- Sauces and dressings: Incorporate into savoury preparations where a smooth texture is preferred.
- Bread and doughs: Experiment with koji in bread, noodles, and other dough preparations.
- Everyday recipes: Mix into yogurt, milk, or soy milk, or incorporate into other recipes according to the desired application.
How to Use
Miyako Koji Powder can be incorporated directly into liquids and mixtures or used to prepare fermented seasonings. For shio koji, combine with salt and water according to a suitable recipe. For amazake, use with cooked rice and water under the temperature and time conditions specified by the recipe.
Because the powder is more finely processed than conventional dried rice koji, preparation methods and quantities may differ. Follow recipes developed for powdered koji rather than assuming a direct one-to-one substitution by volume.
Koji enzyme activity depends on temperature, moisture, and preparation conditions. This product is powdered cultured rice koji, not pure koji starter spores for inoculating uncultured rice.
