Fukuoka Unshu Mikan, or Satsuma Mandarins, are seedless, easy to peel by hand, and known for their sweetness. The long sunlight hours of the region where the mikan are produced enhance their sweetness. The soil promotes drainage, which is essential to prevent overwatering from ruining the crop's taste. Mikan trees naturally alternate between high-yield years and low-yield years. To maintain quality between fluctuating harvests, the trees are closely monitored and managed. Mikan are stored under controlled temperature and humidity, which allows the fruit to develop mild acidity and enhanced sweetness. Calcium is regularly applied to prevent damage to the peels. In July, farmers use permeable mulch to keep the soil at a specific moisture which helps concentrate the fruit's sweet taste.
