Messages From Our Buying Customers

The quality of rice koji here is good, so I purchased the barley koji as well. I made the miso I consumed at home by myself, and I found out the taste of miso changes considerably depending on the quality of the koji used.
This product has good quality, and I like it because it can give a good richness to the miso. I think I will use it again. Thank you.

I usually use rice koji, but this time, I tried to use barley koji to make barley miso. I was able to prepare it with the same method as rice koji without any problems.
The miso will be fermented and ready around next January. I hope it will be delicious!


This product has solid barley grains. I'm looking forward to using it for making barley miso. Also, it's good that it doesn't contain any additives and has a long expiration date.


I found your product when it's hard to get domestic barley koji, and it's also a hassle to make it from scratch. This product is very convincing both in terms of quality and price. I will use it again.


This product is helpful because of its long expiration date and I can use it little by little. I plan to use it for making salt koji (shio koji) and homemade barley miso.


I bought it for making miso. It takes a while to soak it in water, but I could use it without any problems. It seems that it is made diligently and easy to use.

Things to Prepare

● Dried Koji

How to Rehydrate

1. Spread the dried koji on the tray: press the dried koji with your fingers while the dried koji is still on the bag to separate the grains. Then spread them out on a large tray.
2. Use water to rehydrate: one bag of dried rice koji (860gr) requires about 200ml of lukewarm water. If you're using dried wheat/barley koji, use 330ml of lukewarm water.

4. Finish: Rehydrate your dried koji in lukewarm water for about 1 hour and it is ready to use.

Use lukewarm water to rehydrate your dried koji. Do not use hot boiling water.
