However, the dried bonito had not necessarily been hard since ancient times.
It was only what is merely dried with the sun a long time ago.

It boils about 15~40 minutes With 97~98 ℃ hot water.
Boning , cool and drains.
What was made now is boiled and half-dried bonito.
And 4 or 5 sheets are put into a wooden box in piles.
After fumigate it in drying room, it applies for several days and makes it dry.
This work is repeated several times.
The fillet finishing this process is called 'arabushi'.
What molded this into the form of the ship is called 'hadakabushi'
And this will be dried in sunlight for 4 or 5 days, and mold attachment will be carried out.
Hadakabushi is put into the barrel about two weeks, and the dried bonito bacillus which lived in the barrel is generated on the surface.

Koji mold and a dried bonito
A bathroom, a kitchen, a rainy season.
We are afflicted by mold in the place where the damp humidity is high.
Therefore, mold likes a humid place because mold needs much moisture for growing up compared with other microbes.
It is also the same as when making a dried bonito.
Koji mold called dried bonito bacillus lives in the barrel.
By putting hadakabushi in this barrel, bacilli suck up moisture from the surface of hadakabushi in order to live.
Then, the surface dries and it tries to suck up further much moisture shortly.
It moves to the surface which back moisture dried.
Mold tries to suck up the moisture again.
In this way, the water in dried bonito thoroughly sucked out by mold.
In the state where there is no moisture, microbes cannot be useful as well as us.
That is,since the food in which a microbe cannot live does not rot, it is nonperishable.
This is borne by the big wisdom for saving food in the time without electric appliances.
