Ryujin Organic Umeboshi are delicious, tart-salty pickled Japanese plums that are entirely hand-made by the traditional method. Exceptionally flavorful, the Ume plums used are the immature fruit that are pickled in sea salt for up to a year. Shiso (perilla) leaves are added to impart its deep red color. Mitoku Organic Ryujin Umeboshi Plums are grown in the renowned area of Wakayama in Southwestern Japan. Wakayama is blessed with numerous rolling hills and the perfect climate for ume cultivation. Thanks to the Kuroshio Current which brings warm water from Okinawa, these plums enjoy a long year-round mild temperature and abundant sunshine. The result is a rich, complex flavor and an appealing round shape.
