The amazake that I made from this dried koji is outstandingly delicious Dried koji that Kawashima The Japanstore sold was very high quality, and the price is very reasonable. I've made amazake with many kinds of koji before, but this one stands out the most. My husband who is a british also love it as well. From now on I'll stick with this koji when I'm making amazake.


Good quality product! I got through hot summer and cold winter with amazake made from this koji. Not only does this koji has a high quality, but it also works really well. I'll buy it again.


I made a very nice amazake with this Lately, I've been getting into making amazake at home. So I tried different kinds of koji. I have a tendency to use this koji again and again. It does make the best amazake in my opinion. Definitely will buy again.


Truly delicious! This year I made miso by myself, I use all kinds of koji but this one is the most delicious. I made the best miso with this, and it is also good to make amazake. Even my mother who lives in the countryside love it. I will purchase again in the future.


It's very convenient to store at home I bought this to make salt koji at home. At first I was quite nervous to use dried koji for the first time. But in the end there is no problem at all and I succesfully made salt koji with it. With one third of koji from the bag, I made about 900ml of salt koji. I use salt koji to make pickles, cook meat, and cook fish. The taste was more delicious than usual. Dried type koji can last for a long time, it is very convenient to store at home.

How to Make Salt Koji With Dried Koji And Honey Container

Honey Container 1000ml

If you use Honey Container to make salt koji, i will be very convenient.

You can make salt koji just with rice, water and Honey Container. Since the process doesn't require your hand to directly touch the mixture, it is more hygienic because it's also harder for the germs to enter the container. It will take less time to make salt koji because there is also less quipment to wash. We recommend this method for people who want to challenge themselves to make homemade salt koji with dried koji or regular koji.

You can use salt koji as a seasoning for your veggies. You can also season your fish and meat before you grill them. You just have to marinate them for a few hours, and they will have more umami taste.

Things To Prepare

  • Rice Koji (Dried Koji ) 300gr
  • Salt 60-80gr
  • Water (clean water or mineral water) 500ml
  • Honey Container (can contain more than 900ml)

How To Make

  1. Put 300gr of rice koji inside the Honey Container
  2. Add 60-80gr of salt into the container
  3. After you add koji and salt, close the container lid and shake them well. Make sure they are well mixed.
  4. After the koji and salt is well incorporated, add water. If you put 30~35℃ water, the salt will dissolve easily
  5. After the water is added, close the container lid and shake the mixture again
  6. Let them ferment from 1 to 2 weeks in room temperature
  7. When the mixture is done, have a little taste. If it taste umami and have the right amount of saltiness, your homemade salt koji is done.
