The Korea Pork Association and other Korean organizations visited Japan to study pork grading and management systems, aiming to develop specific grading criteria for black pigs in Korea's Jeju region. In Japan, 23% of slaughtered pigs are not graded, and the government supports pig producers through the Pork Management Stabilization Grant, which covers cost fluctuations. About 50% of farms, representing 80% of pigs, subscribe to this subsidy program, which requires a three-year fund accumulation. Since 2013, no subsidies have been needed as sales prices have surpassed production costs. Japan's pig farming policy also includes support for feed price stabilization and disease countermeasures.
