We have compiled our original recipe for making Japanese Fermented Foods like Natto, Koji, Shio Koji, Amazake, Miso, Tempeh, etc. Download the PDF here.

Please store the hon mirin cool and dark place before and after opening the product, such as a cupboard or pantry.

Hon mirin shelf life is estimated to last for 1 year from the delivery date, opened or unopened.

Please keep it at a low temperature or in the refrigerator before and after opening.

There is a possibility that the fermentation is not going well so it gets a weak result. Please keep warm/ferment again for about 12 hours from the initial 24 hours and see the condition. Please also make sure that all equipment is clean before use to prevent the natto to get a weak result.

You will experience the typical natto smell when making natto at home, but once the homemade natto is refrigerated overnight after the fermentation, it will not have any unwanted smell and will enrich the flavor of natto. Please refer to this page for more info.

Please store in a refrigerator (cold and dark place) with a temperature lower than 15ºC, opened and unopened. The standard storage period is 6 months. Please seal the opened sachet with a ziplock or an airtight container and store it in the refrigerator. Immediate use is recommended.

Please keep it in a well-ventilated, cool, and dark place with a temperature of 30°C/86°F or less. Please put it in a sealed container to prevent insects from entering.

However, the quality and taste may gradually deteriorate after a few periods of opening the packaging. Therefore, we encourage you to purchase the amount according to the pace of your consumption.

Kawashimaya growing community is filled with people that have an interest in making Japanese fermented foods like koji. Refer to the page of How to Make Rice Koji.

Raw koji is rice koji in which the koji is still propagated in the rice. Meanwhile, dried koji is made by drying raw koji to remove moisture and improve storage stability.

Find the dried koji product here.

Once the brown rice and other ingredients (brown rice, salt, and azuki beans) are cooked, keep it warm at 72~74°C (162~165°F) for 3-4 days in a rice cooker. The result could vary depending on the ingredients used. Please refer to this page for more info.
