Everything You Need to Know About Sumo Oranges

sumo orange

Every first few months of the year, farmers located in San Joaquin Valley, California, prepare to harvest a unique kind of orange fruit called the Sumo orange. It has a rough texture, a significant size, and a prominent knot on top—similar to a sumo wrestler’s hairstyle, which is where it got its name.

It’s only until recently when Sumo oranges became popular over the web, with people everywhere wanting to try the fruit because of its distinct appearance and extra sweet taste. Keep reading below to learn more about Sumo oranges and why it’s time to try them out for yourself.

The Origin of Sumo Oranges

Contrary to popular belief, Sumo orange is not the correct term for the famous fruit because it isn’t an orange, but rather, a citrus—which comes from a hybrid of Mandarin, Navel, and Pomelo. The fruit should instead be called Sumo Citrus after its official trademark brand name.

Sumo oranges were first found in Japan, and during the late 1900s, their seedlings were imported to the US. It’s quite difficult to grow the fruit, so Sumo oranges only became available to the public in 2011. At present, California farmers continue to transport Sumo oranges all over the US.

The fruit can only be harvested from January to April because its growing process takes a while to complete. Adding to that is the fact that Sumo oranges are hand-picked and hand-packed with care one by one, so it’s no wonder they cost relatively higher than other regular kinds of citrus fruits. 

The Difference Between Sumo Oranges and Other Oranges

If you’ve never seen a Sumo orange up close, you should know that they’re massive compared to other typical citruses. Unlike a medium-sized orange that weighs five and a half ounces, a piece of Sumo orange is bigger than a handful and weighs a bit over eight ounces.

Since it isn’t genetically developed, a Sumo orange is considered a natural hybrid with distinctive features, such as being easy to peel off its outer layer. Other perks include being a seedless and deliciously sweet citrus fruit, due to its high sugar to acidity ratio. 

The Nutrition Content of Sumo Oranges

If you’re concerned about your health and wellness and want to know the nutritional facts about Sumo oranges, based on their website, a piece of Sumo orange contains the following:

Calories: 147

Carbohydrates: 35 grams

Fat: 0 grams

Fiber: 3 grams

Protein: 3 grams

Sodium: 0 grams

Total sugars: 29 grams

While its sugar content may seem like a lot, they are only natural sugars. Of course, due to the size of a Sumo orange, they have more sugar compared to common oranges. With that being said, if you can’t see yourself finishing the whole fruit in one sitting, you can always consume half of it and save the other to eat at the end of the day!

Having a Sumo orange works to support your healthy eating and nutritional habits because it contains 163% Daily Value for vitamin C and 10% for potassium. Potassium is a much-needed nutrient to keep your heart and muscles functioning properly, your blood pressure low, and fluid retention at bay.


Now that you know more about Sumo oranges, including where they came from, their nutritional content, and what makes them so unique, you may be thinking of ways to eat them. While consuming them on their own is still the best option, you can also try adding the fruit into your overnight oats, smoothies, salads, or other snacks you think they might go well with.

Remember that Sumo oranges are only available between January and April, so while they’re still in season, you should consider heading to the nearest market that offers Sumo Citrus before you miss the chance!
