Crazy Shaped Watermelons, the secrets of the Japanese luxurious fruit

Japan is a country that people usually associate with innovation, not only in technology with the hi-tech home appliances, games and fun gadgets but also in agriculture and food production, with the development of crossbreeding plants and growing techniques that results in high-quality products and new types of vegetables and fruits like white strawberries, broccolini (a cross between broccoli and kale) or purple carrots.

Between these innovations you will find in every corner of this country, shaped watermelons are one famous attraction especially during summertime, when the juicy composition of the fruit makes it one of the best fruits to prevent dehydration and to refresh. Shaped watermelons started to be produced in Kanagawa prefecture in 1980’s in order to fit better in compact Japanese refrigerators at that time. The first one created was cubic, a good shape not only to be easily stored but also to prevent it from rolling, and the increasing demand of them stimulated the production of many other shapes like heart-shaped, square, pyramid or even a human face watermelon!


The shaped watermelons are not genetically modified to grow in the particular shape. The format of it can be changed with acrylic shaped molds, where the watermelons are placed when they are still small in the vine. When the melons grow, they naturally assume the shape of the mold. The method seems simple but many of these fruits took years of research to get their shape properly. They also require extra care to be produced. The watermelons are monitored in a daily basis in order to provide the necessary water and nutrients to the fruit, to pest-control and to remove the molds at the correct time. One mistake during the process can destroy months of the farmer’s work.

In recent years, not only in Japan but also abroad, the demand for these watermelons is high. Despite the fact it’s said they are not as sweet as the common one because they are grown in a mold, preventing them to achieve their full maturity, the special shape of these fruits makes them expensive and a desired ornamental item. Each typical square watermelon is sold for approximately $80 – $100 dollars in Japan, but they can cost much more if they are a special designed shape or a limited edition. For example, the pyramid shaped and the human face one can cost around $500. The mini heart-shaped watermelon costs around $200, and the large version will be around $350. They are usually wrapped in a beautiful luxury package, what makes them a real tourist attraction and an example of how creative and innovative the Japanese people can be.
