Thank you for your continued patronage of Kojiya Sanzaemon.

We have decided to revise the prices of Kojiya Sanzaemon's fresh koji and dried koji starting Monday, June 20th, 2022.

When we started selling koji over the internet over 20 years ago, there were only a few online sites where you could buy it. Therefore, with the desire to "first get more customers to know about and use koji," we prioritized the spread of koji, lowered the price more than we had expected, and have never revised the price since then.

On the other hand, after reviewing our prices in light of the recent economic situation, we realized that it would be difficult to continue our koji sales business if things continued as they were.

We at Kojiya Sanzaemon would appreciate your understanding that this is a necessary measure in order for us to continue contributing to improving the experience value of koji and to continue to refine our quality and service without any difficulty.

We apologize for the inconvenience this price increase will cause to our existing customers. We are also considering introducing services that will allow you to make purchases at a discount, so we appreciate your continued patronage.

May 2022
