In the previous article, we told you that acerola only grows outdoors in Okinawa. But what we didn’t tell you is that the relationship between Okinawa and acerola did not begin well. In fact, the opposite was true. For more than twenty years after their first meeting, acerola was completely forgotten on this island.
1958 — Acerola Arrived in Okinawa as One of Six Tropical Fruits
To help rebuild post-war Okinawa, Professor Henry Nakasone of the University of Hawaii brought in seedlings of six different tropical fruit trees. The year was 1958. Mangoes and papayas — fruits now firmly established as Okinawan specialties — were introduced during the same effort.
Acerola was one of those six.
But while the other five fruits gradually adapted to Okinawan soil, acerola alone refused to take root. The climate and soil at the time did not suit it well, no one had the know-how to cultivate it, and even when fruits finally appeared, they would spoil within about three days. A crop that could not be turned into cash gave farmers no reason to plant it.
And so acerola was left as a small handful of seedlings at the Okinawa Prefectural Agricultural Experiment Station, forgotten by almost everyone for over twenty years.
The Paradox of Why Okinawan Acerola Was Forgotten for Two Decades
The biggest reason acerola failed to spread was, ironically, the very delicacy of the fruit itself.
To protect its vitamin C, acerola has a thin, soft skin — and precisely because of that, it spoils easily. It cannot survive shipping. It cannot be stored. To make it work as agriculture, you would need a system to process it the moment it was harvested. But at the time, no one was thinking about building that system.
Looked at another way: acerola was a fruit so rich in nutrition that it stood, for years, in front of the wall called distribution.
The Turning Point Came from a Single University Student
In the late 1970s, a student at the University of the Ryukyus encountered acerola in an agricultural class. His name was Yasufumi Namizato — the man who would later found Acerola Fresh.
What he learned in class was this: acerola contains more vitamin C than any other fruit on earth. And at that very moment, a vitamin C boom was sweeping across America. “It will reach Japan within ten years,” he was convinced. He spent the next six years, all the way through graduate school, immersed in acerola research.
He sought out the single remaining acerola tree at the Okinawa Prefectural Agricultural Experiment Station and began to study how it could be grown. The passion that began there would eventually transform Motobu Town into the only acerola-producing region in Japan.
That story is for the next article.
Frequently Asked Questions
- When was acerola brought to Okinawa?
- Seedlings were brought to Okinawa from Hawaii via the United States in 1958. At the time, Okinawa was still under U.S. administration, and several tropical fruit trials were being conducted as part of post-war agricultural recovery.
- Why was acerola overlooked for more than 20 years?
- Fresh acerola spoils within about three days of harvest, so a distribution network could not be established. The fruit also looked similar to a cherry but had a sharper sourness, which did not match local food habits at the time. Only when juice and puree processing technology matured in the 1980s did acerola finally attract attention.
- Where is most Okinawan acerola grown today?
- Motobu Town is known as the largest production area in Japan. Its climate, soil, and farming community are all well suited to acerola, and most Okinawan acerola continues to ship from Motobu Town today.
