How do you eat dekopon? Peel it by hand like a mandarin; the loose skin comes away in one piece and the segment membranes are thin enough to eat without stripping. Usually seedless, so there is nothing to work around.

What does it taste like? Very sweet with low acid and a clean mandarin aroma, the flesh tender and almost juice-heavy enough to collapse.

Dekopon was bred in 1972 but not sold until 1991 — the breeders initially rejected it because the knob at the top made it look misshapen, and it reached market only after taste testing overruled appearance.

How to tell when dekopon is ripe

Deep even orange with the stem-end knob well formed, and heavy for its size. Commercial fruit is held in storage after picking to let the acid fall — which is why season matters more than appearance with this one.

How to store dekopon

About a week at room temperature, two to three weeks refrigerated. The loose skin protects the fruit well, but it bruises where the knob meets the body, so do not stack heavily.

Dekopon: frequently asked questions

What does dekopon taste like?

Very sweet with low acid and a clean mandarin aroma, the flesh tender and almost juice-heavy enough to collapse. Peels away from the segments in one piece with almost no pith, and is usually seedless.

When is dekopon in season?

How do you eat dekopon?

How do you know when dekopon is ripe?

Deep even orange with the stem-end knob well formed, and heavy for its size. Commercial fruit is held in storage after picking to let the acid fall — which is why season matters more than appearance with this one.

Is dekopon good for you?

Dekopon is mostly water with natural sugars, a little fibre, and assorted micronutrients — a hydrating everyday addition to your overall fruit intake rather than a standout for any one nutrient.

How much dekopon should you eat?

A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.

Are Dekopon, Shiranui and Sumo Citrus the same fruit?

Yes — one cultivar, three names, and the difference is trademark rather than botany. Shiranui (or shiranuhi) is the varietal name. Dekopon began as a brand controlled by JA Kumamoto Keizairen and has become the generic Japanese term. Sumo Citrus is the trademark under which it is grown and sold in California. In South Korea, chiefly on Jeju Island, the same fruit is Hallabong.

Why does a Dekopon have a bump on top?

It is a genetic trait of the cultivar, not a defect or a growing fault. The raised collar at the stem end gives the fruit its Japanese name — deko means the protruding bump, and pon comes from ponkan, one of its parents. It nearly ended the variety: breeders initially set it aside because the shape looked misshapen, and it reached market only after taste testing overruled the appearance.

What is a Dekopon crossed from?

It is a Kiyomi crossed with a Ponkan mandarin, made in 1972 at the Kuchinotsu experimental station in Nagasaki Prefecture. Kiyomi is itself a satsuma crossed with a Trovita orange, so a dekopon carries satsuma, sweet orange and ponkan ancestry — which is where the combination of easy peeling, very low acid and high sugar comes from.
