Square watermelons. They’re eye-catching, unusual, and often spark curiosity. But beyond their novelty, what’s the real purpose behind these geometric fruits? Are they simply a gimmick, or is there more to the story than meets the eye? Let’s delve into the fascinating world of square watermelons, exploring their origins, cultivation, practical benefits, and the cultural significance they hold.
The Genesis of the Square: How It All Started
The story of the square watermelon begins in Japan in the late 1970s. Tomoyuki Ono, a graphic designer, is credited with the initial idea. His vision wasn’t about creating a new variety of watermelon, but rather solving a practical problem: space constraints in Japanese refrigerators. Traditional round watermelons are notoriously difficult to store efficiently.
Ono envisioned a watermelon that could be easily stacked and wouldn’t roll around, maximizing storage space in cramped urban apartments. The solution? A cube-shaped watermelon. The concept quickly gained traction, not just for its practicality, but also for its novelty.
The Science of Shaping: Growing Square Watermelons
The process of growing square watermelons isn’t about genetic modification or some futuristic agricultural technology. It’s surprisingly simple, relying on a technique called formative pruning.
The Mold Technique
The key to achieving the square shape lies in the use of a mold. Here’s a breakdown of the process:
- Selecting a Young Watermelon: When a watermelon is still small, about the size of a grapefruit, it is carefully chosen for its healthy growth.
- The Square Enclosure: A transparent, square-shaped box, typically made of acrylic or plastic, is placed around the developing fruit while it’s still on the vine.
- Controlled Growth: As the watermelon grows, it is confined by the walls of the box. It fills the space, gradually taking on the square shape dictated by the mold.
- Harvesting at Maturity: The watermelon is harvested when it completely fills the mold, achieving its desired cubical form.
The transparent mold allows sunlight to reach the watermelon, ensuring that it ripens properly. The farmer must carefully monitor the growth of the watermelon within the mold to prevent it from cracking or becoming misshapen. The timing of placing the mold is crucial; too early, and the watermelon might not develop properly; too late, and it won’t conform to the square shape.
Challenges in Cultivation
While the concept is straightforward, growing square watermelons isn’t without its challenges. The mold can sometimes restrict growth, leading to smaller watermelons or uneven ripening. Cracking and bruising are also potential problems, as the fruit is forced to conform to an unnatural shape. Furthermore, not all watermelon varieties are suitable for growing in molds. Varieties with thinner rinds are more susceptible to damage.
Beyond Novelty: Practical Advantages and Disadvantages
While the initial purpose was practical, the square watermelon has evolved to represent a blend of functionality and aesthetic appeal.
Space Efficiency: The Original Intention
As Tomoyuki Ono intended, square watermelons are indeed easier to stack and store compared to their round counterparts. This space-saving advantage is particularly valuable in densely populated areas where refrigerator space is at a premium. The ability to stack multiple square watermelons without them rolling around is a significant improvement in storage efficiency.
Transportation Benefits
The square shape also offers advantages in transportation. They can be packed more tightly and efficiently in trucks and containers, reducing wasted space and potentially lowering shipping costs. This efficient packing can also minimize damage during transit, as the watermelons are less likely to shift and bump against each other.
The Price Factor: A Luxury Item
However, these advantages come at a cost. Square watermelons are significantly more expensive than regular watermelons. The labor-intensive process of placing molds and monitoring growth, combined with the higher risk of crop loss due to cracking or misshaping, contributes to the elevated price tag. They are often considered a luxury item, purchased for their novelty rather than their practicality.
Taste and Texture: Is There a Difference?
While the shape is different, the taste and texture of square watermelons are generally the same as those of regular watermelons of the same variety. The molding process doesn’t typically affect the internal quality of the fruit. However, some argue that the restricted growth within the mold can sometimes lead to slightly less sweetness or a less juicy texture. This is often dependent on the specific growing conditions and the variety of watermelon used.
Cultural Significance and Symbolism
Beyond their practical and aesthetic qualities, square watermelons have acquired cultural significance, particularly in Japan.
Status Symbol and Gift Giving
In Japan, square watermelons are often seen as a status symbol. Their high price and unusual appearance make them a popular gift item, especially during special occasions and festivals. Giving a square watermelon can be seen as a gesture of generosity and sophistication.

In some areas, they are seen as a fun and unusual novelty item, while in others, they are considered too expensive and impractical. Consumer perception plays a significant role in determining the success of square watermelon cultivation in different markets.
The Future of Shaped Produce
The square watermelon is just one example of how agricultural techniques can be used to shape and mold produce into unusual forms. This raises the question of what the future holds for shaped produce.
Other Shaped Fruits and Vegetables
The success of square watermelons has inspired experiments with other shaped fruits and vegetables. Heart-shaped cucumbers, star-shaped tomatoes, and even Buddha-shaped pears have been developed using similar molding techniques.
Potential Applications and Benefits
Shaped produce has the potential to offer a variety of benefits. It can improve storage efficiency, reduce transportation costs, and enhance the aesthetic appeal of food. It can also be used to create fun and engaging products for children, encouraging them to eat more fruits and vegetables.
Ethical Considerations
However, the practice of shaping produce also raises ethical considerations. Some argue that it is unnatural and potentially harmful to the plants. Others question whether the benefits outweigh the costs, given the labor-intensive nature of the process and the potential for crop loss. It is important to carefully consider these ethical issues as the trend of shaped produce continues to evolve.
Is It Worth It? A Final Verdict
So, what’s the ultimate purpose of square watermelons? Are they a practical solution, a novelty item, or something more? The answer is likely a combination of all three.
- They offer some practical benefits in terms of storage and transportation.

Why are square watermelons grown in a square shape?
The primary reason for growing square watermelons is convenience. The square shape makes them easier to stack and transport, maximizing space efficiency during shipping and storage. This is particularly beneficial in urban areas like Japan, where space is often at a premium.
Beyond practicality, square watermelons have also become something of a novelty item, fetching a higher price than their round counterparts. Their unusual shape makes them a popular gift and conversation starter, adding to their market appeal.
How are square watermelons actually grown?
Square watermelons are grown inside transparent, square containers made of plastic or glass. When the watermelon is still small, it’s carefully placed inside the mold. As the fruit grows, it conforms to the shape of the container, resulting in the desired square shape.
The process requires close monitoring and careful timing. Farmers must place the watermelon in the mold at the correct stage of development to avoid damaging the fruit. The mold also needs to be strong enough to withstand the pressure of the growing watermelon.
Do square watermelons taste different from regular watermelons?
Generally speaking, square watermelons don’t taste noticeably different from round watermelons of the same variety. The square shape is purely a result of the growing process, and it doesn’t affect the fruit’s inherent flavor or texture. However, some argue that because they are often harvested early to maintain the shape, they may not be as sweet as naturally ripened, round watermelons.
It’s important to remember that taste is subjective and can be influenced by factors beyond shape, such as the specific watermelon variety, growing conditions, and ripeness at the time of harvest. So, while the shape doesn’t inherently alter the flavor, other factors could contribute to subtle differences.
Are square watermelons more expensive than regular watermelons?
Yes, square watermelons are typically much more expensive than regular, round watermelons. This higher price is primarily due to the specialized growing process, which requires more labor, resources, and attention than traditional watermelon farming. The cost of the square molds themselves also contributes to the overall expense.
Furthermore, the novelty factor of square watermelons plays a significant role in their higher price. Because they are considered a unique and somewhat luxurious item, they are often sold at a premium to consumers who are willing to pay for their unusual shape and presentation.
Where did the idea of square watermelons originate?
The concept of growing square watermelons originated in Japan in the late 1970s. A Japanese graphic designer named Tomoyuki Ono is credited with the idea. He initially wanted to create watermelons that would be easier to stack and store in refrigerators.
The idea quickly gained traction due to the practical benefits of the square shape and its novelty appeal. Japan’s limited space and innovative agricultural practices further contributed to the successful development and commercialization of square watermelons.
Is growing square watermelons sustainable?
The sustainability of growing square watermelons is a complex issue with both positive and negative aspects. On the one hand, the improved space efficiency in transportation and storage can reduce fuel consumption and waste, which are environmentally beneficial.
