La Satsuma mandarin, known for being the citrus fruit sweeter and easier to peeloccupies a prominent place among mandarin varieties, both for its organoleptic qualities and for its history, hardiness, and health benefits. Originally from Japan and later spreading to citrus-growing regions around the world, the Satsuma is prized both for home consumption and in the food industry, thanks to its unique combination of flavor, aroma, hardiness, and ease of handling.
What is the Satsuma mandarin and where does it come from?
La Satsuma (Citrus unshiu) is a variety of mandarin originating in Japan, where it was selected and cultivated for centuries due to its excellent adaptation to varied climates and the demand for a fruit early, sweet and seedlessIts name comes from the ancient Japanese province of Satsuma, a region where it gained special importance in local agriculture.
It is characterized by having a later flowering cycle than most mandarins, but a ripening extremely earlyThis characteristic makes it the first mandarin variety to reach markets in many citrus-growing regions, and it is commonly found from late summer onwards.
In Europe, the Satsuma adapted quickly, especially in Mediterranean countries like Spain, where it was introduced and established itself as one of the predominant varieties for decades, occupying large areas of cultivation before the massive arrival of clementines.
Botanical and morphological characteristics: how to recognize Satsuma
The Satsuma mandarin is a tree of medium size, with dark, lanceolate, glossy leaves. Its fruit is recognizable by:
- Flattened shape: They are usually somewhat flattened, not spherical.
- Size: Generally small to medium, between 90 and 110 grams per fruit.
- Color: From orange-yellow to salmon-orange, varying according to ripeness and variety.
- Skin: Thick, rough, but very easy to peel with your fingers, without the need for a knife.
- Propensity to puffing: When it begins to ripen, the skin loosens with respect to the pulp, making it easier to separate.
- Absence of seeds: Most Satsumas, especially Owari and Okitsu, are practically seedless (seedless).
Another distinctive feature of the tree is that it's usually the last to flower, but the first to be harvested. The harvesting cycle typically runs from late summer until well into winter, thanks to the various subvarieties available.
Main varieties of Satsuma and harvesting calendar
- Iwasaki: The earliest variety, small to medium sized, barely seeded and very flattened shape. It is harvested from late August through September, even with part of the skin still green, but fully ripe inside.
- OkitsuOne of the most popular varieties for its balance of sweetness and juiciness. It is widely cultivated and harvested between September and October. It has a delicate flavor and thin skin.
- Owari: Highly appreciated, slightly later ripening (October and November). Medium-sized, very juicy fruits and without seedsIt is one of the preferred options due to its hardiness and productivity.
- Queen and Clausellina: Later varieties, with similar characteristics in terms of sweetness, size and ease of peeling.
The great advantage of the Satsuma is its prolonged harvest schedule, which can extend from late summer to early winter, providing fresh fruit for a longer period compared to other mandarins.

Satsuma is the protagonist in the production of canned segments, preferred for their texture, sweetness, and lack of seeds. Countries such as Spain and Japan are leaders in the export of this type of product, which enjoys widespread acceptance worldwide in both children's and adult nutrition.
