■Core Competence

Pioneer of soybean processed products
Marusan-Ai has the required technologies and products to produce various kinds of miso such as soybean miso, rice miso, wheat miso, and blended miso, which are rare in the miso industry. Furthermore, we are producing special miso products including “ajinokyoen mutenkanama” and “miso with reduced bacteria” by using microorganisms such as yeast and lactic bacteria.
Marusan-Ai holds the second largest market share in soymilk products using technologies for deodorizing sterilizing, and fermenting lactic acid.
We have acquired the rare Organic JAS certification for our plant. Marusan-Ai produces and distributes “organic plain soymilk” using soybeans produced by foreign contracted organic farmers.
