Pineapple fields stretch across the rolling hills overlooking the sea. Located on the east coast of northern Okinawa Island, Higashi Village in Kunigami District is the home of “Gold Barrel,” a premium pineapple that accounts for just 5% of Japan’s total production. What is the story behind the “King of Pineapples”—the Gold Barrel—and the aspirations of its young growers?

The History of Pineapple Cultivation in Okinawa Prefecture

Okinawa Prefecture accounts for nearly 100% of Japan’s domestic pineapple production, with an annual harvest of approximately 7,000 to 8,000 metric tons. It is said that pineapple cultivation began in 1866 when seedlings washed ashore from a Dutch ship that had run aground off the coast of Ishigaki Island. After World War II, when cultivation and breed improvement for canning began in earnest, pineapples grew to become one of the two major staple crops alongside sugarcane by the 1960s.

However, the once-thriving pineapple industry suffered a major blow with the liberalization of canned product imports in 1990, and cultivation of the Hawaiian variety “N67-10”—which had been the mainstay for processing—began to decline.

Shift to high-value-added varieties for fresh consumption

Although pineapple cultivation had declined at one point, Okinawa Prefecture is shifting toward growing high-value-added varieties intended for fresh consumption. Today, the prefecture produces “Snack Pine” (official name: Bogor Pine), which can be torn apart by hand and eaten as a snack, the small, white-fleshed “Peach Pine” (official name: Soft Touch), the intensely sweet “Sandolce” (official name: Okino P17), the “White Coco” (official name: Okino P19) with its coconut-like aroma, and the premium “Gold Barrel” (official name: Gold Barrel Pine). These and many other fresh-eating varieties have been developed and are now being cultivated, steadily expanding their market share.

The Birth of the Premium “Gold Barrel” Pineapple

“Gold Barrel,” registered as a new variety in 2006, originated in Higashimura. It was developed over a period of approximately 20 years from a seedling obtained in 1989 at the Okinawa Prefectural Agricultural Research Center by crossing “Cream Pine” and “McGregor ST-1.” The variety was named for its golden-colored flesh and barrel-like shape.

The most distinctive feature of Gold Barrel is its high sugar content. While the sugar content of typical pineapples ranges from 14 to 16 degrees, Gold Barrel has a much higher sugar content of 17 to 19 degrees. Furthermore, the fruit is so tender that even the core is edible, and it has less of the characteristic sharp tartness typical of pineapples. When you take a bite, it’s melt-in-your-mouth tender and juicy, and because it has very little fiber, it doesn’t leave a gritty texture in your mouth. With its refined sweetness and rich aroma, and weighing approximately 1.5 to 2 kg per fruit, it has gained attention as a premium pineapple for gift-giving.

Tadao Tamaki, the creator of “Gold Barrel”

Tadao Tamaki of Tamaki Farm—a pioneer in pineapple cultivation in Higashimura and an Honorary Agricultural Advisor for Okinawa Prefecture—played a pivotal role in the creation of this new variety. Starting with 11 frail seedlings he had received, Mr. Tamaki repeatedly selected and nurtured them, and through many years of effort and research, he cultivated “Gold Barrel” into a truly golden-hued fruit.

Among the “Gold Barrel” pineapples Mr. Tamaki grows himself, those that are particularly exceptional in terms of taste, color, size, and shape are named “TADAO GOLD.” Known as the highest-grade variety of “Gold Barrel,” they are selected from only a few percent of the total crop.

The Legacy of Pineapple Farming

Yoshiyuki and Kie Shinzato, who run “Shinzato Fruit Farm” in Higashimura, are the next generation of growers who learned the ins and outs of Gold Barrel cultivation from Mr. Tamaki, who has devoted over 50 years to pineapple farming.

Kie is Mr. Tamaki’s daughter, and she had watched him grow pineapples since she was a child. However, it wasn’t until she entered the workforce that she realized just how remarkable her father’s pineapples were. She says it was after she started working as a pastry chef in Naha City.

Nearly 20 years ago, the pineapples her workplace was sourcing turned out to be Gold Barrel varieties grown by her father. She heard rumors from people around her that “TADAO GOLD” was famous for its delicious taste, and that’s when she realized just how exceptional they were. Thinking, “This might not be a job anyone can do,” she began working side by side with Yoshiyuki—who was born and raised on a part-time mango farm in Nanjo City—to take on the challenge of growing Gold Barrel pineapples.

Gold Barrel, Grown on the Land of Higashimura

Higashi Village, home to Shinzato Orchard, is not only one of the prefecture’s leading pineapple-producing areas but is also known as “Yanbaru,” a region where rich natural landscapes—including mangrove forests—and unique ecosystems remain well-preserved. In the vast fields where patches of red soil peek through, pineapples that have grown to about waist height stand densely planted in neat rows.

Higashimura’s red soil and climate, ideal for pineapple cultivation

One reason pineapple cultivation thrives in Higashimura is the acidic, well-drained red clay soil that pineapples prefer most. Additionally, the terrain allows minerals from the sea to seep into the soil, and summer temperatures range from 30 to 35 degrees. These conditions produce pineapples with high sugar content.

Soil preparation that capitalizes on the advantages of this soil is a crucial factor in pineapple cultivation.

Soil preparation begins by using a power shovel to till the soil to a depth of about 1 meter. Since water is the pineapple’s arch-enemy, this process creates air pockets in the soil, improving drainage. The tilled soil is then left to rest for three months, exposed to natural rainfall to allow moisture and minerals to permeate the soil while incorporating air, helping it regain its vitality. This process also prevents problems such as stunted growth caused by continuous cropping.

And apparently, the most important aspect of soil preparation is weed control. “My father-in-law tells me most often not to let the weeds grow,” says Yoshiyuki. To prevent an infestation of scale insects, they don’t use machines for weeding—they pull them out almost entirely by hand. This labor-intensive and time-consuming approach to soil preparation ultimately contributes to the flavor of the pineapples.

From Planting to Growth to Harvest

Pineapple planting is generally divided into two main periods: spring (March and April) and summer (September and October). Spring planting is timed so that the roots can establish themselves before the rainy season begins in late May. Summer planting is scheduled while monitoring typhoon conditions to ensure the planted seedlings do not rot due to rain.

Once the fruit has grown to a certain size, each one is covered with a hat made of newspaper to protect it from sunburn, and then covered with netting to block strong ultraviolet rays, thereby preventing the skin from burning and spoiling. Additionally, since the large, heavy “Gold Barrel” variety can have its stems snapped by strong typhoon winds, pipes are installed to support the stems.

Gold Barrel pineapples, which are grown with great care in an environment optimized for the crop, are finally ready for harvest approximately three years after the seedlings are planted. Since pineapples generally do not continue to ripen after harvest, they are allowed to ripen on the plant and harvested at the peak of their flavor. As harvest time approaches, the ripeness of each fruit is checked daily, and ripe ones are harvested by hand.

Carrying Dreams in a Gold Barrel

Shinzato Orchard harvests approximately 9,000 pineapples annually. While standard pineapples can be harvested twice in four years, the Gold Barrel variety yields only once every three years. Despite being a difficult variety to cultivate—with limited yields and susceptibility to disease—the growers spare no effort, meticulously preparing the soil and waiting for the fruit to ripen on the tree before picking it at the peak of flavor.

That said, it is this meticulous work that produces the Gold Barrel—a pineapple that is tender right down to the core and boasts a rich, fragrant aroma. “My father-in-law conducts research every day and continues to incorporate new techniques even though he’s over 80. I’m young, but I still can’t keep up with him,” says Yoshiyuki humbly.

While absorbing techniques and knowledge from Mr. Tamaki, he is eager to expand production by gradually increasing the acreage of Gold Barrel—a variety that is difficult to grow and has unstable yields—with the goal of eventually achieving a stable harvest of 12,000 to 13,000 fruits.

Meanwhile, Kie is focused on establishing a shipping system. Gold Barrel, which is allowed to ripen on the tree, has a shelf life of just three days after harvest. The process of polishing each pineapple individually with a cloth and packing them by hand into boxes can take up to 22 hours during peak harvest season. However, they hope to streamline this process by adopting new systems—such as machinery—so they can devote even more time and effort to growing the pineapples.

The couple currently donates their harvested pineapples regularly to local elementary schools and children’s homes. This stems from their desire to change people’s “assumptions” about pineapples: “When we were children, we thought it was normal for pineapples to be a little sour. However, depending on the variety and cultivation methods, they can become this sweet. We want children to know that pineapples are sweet and delicious, and we want to change what people take for granted about pineapples.”

Just as Mr. Tamaki nurtured golden fruits from 11 frail seedlings, that passion and expertise are now being passed on to the next generation. The Gold Barrel pineapples, rooted in the red soil of Higashi Village, will continue to bear sweet fruit, carrying the dreams of these two men.
