  • Production of romaine lettuce in Kagawa Prefecture

    In Kagawa Prefecture, romaine lettuce shipments began in earnest in 2016, mainly in Kanonji City. Approximately 30ha of cultivated area is cultivated throughout Kagawa Prefecture, and the annual sales volume is 740 tons (2022 JA Kagawa Prefecture Lettuce Subcommittee data).
    Kanonji City has a history of growing regular lettuce (hereinafter referred to as head lettuce) as a back crop after rice cultivation, and has been working to improve the soil using organic fertilizers. The climate and soil preparation of the Setouchi region are the strengths of Kagawa Prefecture's romaine lettuce.

  • The harvest season for romaine lettuce is approximately seven months from late October to May. Sowing begins after Obon in August. In warm weather, you can harvest the seeds in about two months, but when it gets cold, the growth slows down and it takes about four months to harvest them. The season is from early December to late March, and the sweetness and flavor increases during the colder months.
    In Kanonji City, a major production area in Kagawa Prefecture, romaine lettuce was certified as a "Kanonji Brand Certified Product*" in 2017.
    *Kanonji brand certified products are agricultural, forestry, and fishery products certified by Kanonji City for the purpose of expanding consumption, sales channels, and promoting the agriculture, forestry, and fisheries industry, as well as processed products thereof.

  • Characteristics of romaine lettuce

    Heading lettuce has leaves that curl inward and has a cabbage-like shape, but romaine lettuce has leaves that stand up like Chinese cabbage and is characterized by its long, vertical shape. The leaves can be up to 30cm long. The outer leaves are a darker green than regular lettuce, and the inner leaves are a lighter green.
    The leaves are thick and have strong veins, so they retain their crunchy texture even when heated, making them suitable for stir-fries and hot pot dishes.

    [Origin of romaine lettuce]
    In North America, it is called romaine lettuce, but in other parts of the world it is known as "costales." Kos comes from the island of Kos, which is a place of origin in the Aegean Sea.
