Fermentation is a mysterious reaction caused by small microorganisms of mere one micron (1/1,000 millimeter), and it is a known fact that its mechanism remains unclear. Even so, in order to achieve proper fermentation, it is very crucial to meet the requirements, such the climate, soil, and vegetation of each land. Also for spontaneous fermentation, utmost attention is required for these environmental changes.

The fermentation house, where the fermentation and maturation of Manda Koso take place, is situated between the small hills of Innoshima and the Seto Inland Sea. It is surrounded by broad-leaved trees, which are planted to create an environment suitable for the growth of microorganisms. We prepare the best-suited environment for promoting sufficient fermentation of meticulously selected ingredients to ensure that Manda Koso is nurtured with the knowledge and data of skilled artisans with many years of experience.
