Every liter passes through a somatic cell counter. In the EU, the legal limit is 400,000 cells/mL. In Japanese artisanal farms, the internal "Ydekitt" standard is <150,000 cells/mL. If a cow exceeds this, her milk is automatically diverted to a separate tank for heat treatment and non-premium use.

After milking, the teats are sprayed with a natural film-forming agent (often containing washi paper fiber or persimmon tannin). This seals the sphincter against bacteria. Farmers then perform "teat scoring" —a visual verification where each teat is graded 1-5 on health. Only cows with a 4+ score progress to the final verification stage. Every liter passes through a somatic cell counter
Unlike the vast, thousand-acre dairy operations of New Zealand or the United States, Japanese dairy farms are typically small to medium-sized (50–200 cows per farm). Due to Japan’s mountainous terrain and limited arable land, efficiency is non-negotiable. But more importantly, the concept of kodawari (a persistent, obsessive attention to detail) governs every action. If a cow exceeds this, her milk is
Japanese farms use pneumatic pulsation systems, but the art lies in the angle of attachment. Farmers are trained to attach the cluster so that it hangs perfectly straight, mimicking the suckling of a calf. The vacuum pressure is lower (42 kPa) than Western standards (46-50 kPa), prioritizing cow comfort over speed. This is the "slow art" of milking—a full session takes 8-10 minutes, compared to 5-6 minutes in industrial systems.
