Koji lid, in Japanese called kojibuta or morobuta, is the proper tool that is essential for professional Koji making. This product itself is limited in the market. Crafted with local natural Japanese cedar wood, this product is constructed by hand one part after another by skillful craftmans.
We received many reviews and comments from our customers who bought this product saying...
I want to make koji with professional tools.
I want to make koji with my own hand and my own rice.
My koji lid in my miso warehouse is too old,, I want to get a new one.
This type of product is also used by our very own shop owner who is skilled at making koji. Koji lid is usually used by professional and people who is experienced. This koji lid is designed for pro as it has a slightly lifted center so the koji can be easily spreaded on the lid (this is important in order to avoid uneven heat distribution that can ruin the yeast propagation process).
In this day and age, brand new koji lid is very valuable. Therefore, if you want to try cooking with koji, don't hesitate to buy this tool and give it a try! Every part of the lid is specifically made with local cedar wood and the bottom plank is finished with wood planer so it has a smooth surface. The bottom planks are made out of straight grain wood and the side planks are assembled a certain way so that the wood knot does not get inside as much as possible. Currently, due to the difficulties in material supply, please consult with us first if you want to buy koji lid in large quantities. Moreover, make sure to order your koji lid before using it in your warehouse.

Role of the Koji Lid
Koji lid, commonly known as kojibuta, is a small container that has been used for a long time in koji making (the process of propagating yeast cell on steamed rice).
Koji making takes place in a hot and humid specialized room called Kojimuro, which takes 48 to 56 hours. However, due to the nature of the room, various parts like the center and corners, front and back, whether it's close to the ceiling or near the tatami floor, can have different temperature and humidity.
Therefore, the rice is divided into small portions on this koji lid, and the lid placement is regularly moved to adjust the conditions of all rice to be the same in terms of temperature and humidity.
By moving and reloading every 3 hours, all the lids that are stacked in the corners of the room are moved to the center, the lids that are in the back are moved to the front, the lids stacked in the upper row are moved to the lower row, and so on. By doing this, the yeast cell will be uniformly propagated in the rice grain.
Advantages of koji lid method: ● Compared to machine-made koji (manufactured by automatically controlling the heat generation of koji), the finish of koji is much better. Even in sake breweries, when it comes to sake that are in junmai or ginjo classification, most of the breweries are made using this lid method. After all, there are some aspects in the world of brewing that are not yet understood by the power of science or machinery. ● The koji finish affects not only sake but also miso and soy sauce. The koji, which is in good quality even after the preparation, works well.
Disadvantages of koji lid method: ● Controlling the temperature. Because temperature control is difficult, it takes more energy and attention. ● Large number of koji lid requires more labor.
