At the main factory in Sanjo, Niigata Prefecture, we carefully and thoroughly carry out pre-treatments to bring out the flavor of the ingredients such as far-infrared rays and heating processes using jet ovens. The factory is equipped with laboratories in which soup stocks are lined up for tasting in each production lot, and an environment in which sensory evaluations can be carried out at any time has is available. Similar to the elaborate classification before the extraction, after the extraction, each soup stock is checked by an artisan for quality. The bonito shavings line has been HACCP-certified. The Shimoda factory below Sanjo is situated on a hill surrounded by forests and manufactures liquid products made with high-quality soft water from Ikasashi River's drainage system.
At the in-house laboratory, scientific analyses of all soup stocks are conducted every day. Analyses quantifying nutritional information, etc. using cutting-edge equipment are conducted and verified from a scientific point of view. Also, we are working in all departments for an early obtainment of FSSC22000.
