Hakkaisan “Amazake Made from Koji”

Here’s an introduction to Hakkaisan’s “Amazake Made from Koji.”

“Amazake Made from Koji” is a rice koji amazake made without any sugar whatsoever; it brings out the natural sweetness of rice by saccharifying its starch.


What sets it apart from other amazake is that it is a food with functional claims—specifically, that it “helps maintain skin moisture” and “regulates the intestinal environment to improve bowel movements.”
Foods with Functional Claims
The Functional Food Labeling System is a system under which, based on rules established by the national government, businesses may label foods with functional claims if they submit the necessary information—including scientific evidence regarding the food’s safety and functionality—to the Commissioner of the Consumer Affairs Agency prior to sale.Unlike Foods for Specified Health Uses (Tokuhō), the government does not conduct reviews under this system; therefore, businesses are required to make appropriate claims based on scientific evidence at their own responsibility.

The product contains two functional ingredients: “Aspergillus oryzae HJ1 strain” and “glucosylceramide derived from koji.”
- Aspergillus oryzae HJ1 strain
- Glucosylceramide Derived from Koji


The details of the notification for foods with functional claims are as follows.
This product contains the Aspergillus oryzae HJ1 strain and koji-derived glucosylceramide. The Aspergillus oryzae HJ1 strain helps regulate the intestinal environment and improve bowel movements. Koji-derived glucosylceramide helps maintain skin moisture.

This amazake is available in three sizes.
- 825 g
- 410 g
- 118 g

The amazake featured here comes in a single-serving size of 118g.

Since it’s a single-serving size, it’s the smallest size at 118g.

Since it’s a single-serving size, the container is small, measuring about 3.94 inches (10 cm) in height.

The lid on the amazake container is the type that peels right off.
My thoughts on drinking amazake

As I pour the amazake into a cup, a refreshing aroma and the subtle, earthy scent of rice gently fill the air.

The amazake poured into the cup is milky white—a little whiter than the one in the photo.

When I scoop it up with a spoon, it has just a slight thickness, and there are no grains of rice in it.

As soon as I took a sip, the gentle texture of the amazake, combined with a subtle, simple aroma of rice, filled my mouth.

This amazake has a refreshing taste, yet I was able to fully savor its gentle, simple sweetness.

Since the only ingredient is rice koji (made from Japanese rice), I was able to enjoy the simple flavor of amazake.
