Umeboshi is a traditional Japanese preserved food made by pickling ume (Japanese plums) in salt and then sun-drying them. Known for its intense sour and salty taste, umeboshi is often used as a filling for onigiri (rice balls) and as a side dish in bento (lunch boxes). It has a long history in Japanese cuisine and is also recognized as a health food.
Taste, Flavor, Texture
- Taste: Umeboshi has an intense sourness and a strong salty taste. Traditional varieties are heavily salted, offering a powerful, tangy flavor. Recently, less salty and mildly sour options like “honey umeboshi,” which has a touch of sweetness, have become popular, providing a sweet-and-sour alternative.
- Flavor: Umeboshi has a distinctive aroma that comes from fermentation, adding to its appetizing quality. The addition of ume vinegar and shiso leaves deepens its unique aroma, giving it a refreshing quality.
- Texture: Umeboshi typically has a soft, melt-in-your-mouth texture. As you bite into it, the juicy flesh releases a burst of sourness that fills the mouth. The slightly firm skin adds a gentle chewiness, enhancing the overall texture experience.
Health Benefits of Umeboshi
Umeboshi is believed to offer several health benefits.
- Fatigue recovery: Umeboshi is rich in citric acid, which is said to help alleviate fatigue.
- Digestive aid: It promotes the secretion of gastric juices, aiding digestion.
- Antibacterial properties: The strong acidity of umeboshi is believed to help prevent foodborne illnesses and has antibacterial effects.

(Shiso-Pickled Umeboshi)

How Umeboshi is Made
Umeboshi is made in warm, humid climates with sunny, dry days after the rainy season. Strong sunlight is essential for drying the plums. Regions like Wakayama Prefecture are well-known for producing umeboshi.
- Harvesting the ume: Umeboshi is made using either green or ripe ume plums, harvested at the right time when the fruit is at its best.
- Pickling in salt: The ume plums are washed, dried, and heavily salted. This process removes moisture from the plums, allowing them to be preserved for long periods.
- Sun-drying: After the plums are thoroughly pickled, they are sun-dried, which helps to further dehydrate them and concentrate their flavors.
- Shiso pickling (optional): For red umeboshi, shiso leaves are added during the pickling process, giving the umeboshi a reddish color and adding a distinct herbal flavor.
Historical Background
Umeboshi is a traditional Japanese preserved food made from pickled plums, introduced from China during the Nara period (8th century). Initially used for medicinal purposes, it became popular among the nobility during the Heian period. In the Sengoku period, samurai valued umeboshi as portable food and medicine. Its strong acidity and high salt content allowed for long-term preservation, and it eventually became a staple in the diet of common people. Today, umeboshi remains a beloved part of Japan’s culinary tradition.
