Across three articles, we’ve told you about acerola. Its astonishing nutrition, its forgotten twenty years, and the industry a husband and wife carved out. In this finale, we’d like to close the series by telling you how acerola is grown in Motobu Town today — and why this one glass can only be tasted here.
The Meaning of the Donut-Shaped Pruning in Okinawan Acerola Fields
Walk into an acerola orchard in Motobu Town and you’ll notice the trees take a strange shape. As if the center has been carved out — like a donut. This is not aesthetics. It is a design for flavor.
So that the sunlight reaches every single fruit evenly, growers prune carefully, every day. Acerola that catches every drop of Okinawa’s strong sunlight turns a vivid red, and the sweetness and tartness condense inside. No pesticides. No coloring. That red is made of nothing but the sun and the work of human hands.
The cultivation method itself was something Yasufumi Namizato discovered through research he began in graduate school. The shape of every tree in the orchard still carries traces of his work.
Why Okinawan Acerola Can Be Harvested Five Times a Year
Acerola can be harvested five times a year. For a farmer, this is not just a matter of yield.
In a place like Okinawa, where typhoons are frequent, a crop that depends on a single harvest a year carries enormous risk. With acerola, even if one harvest is destroyed by a typhoon, the next one is already on its way. One of the reasons Yasufumi saw possibility in this fruit lies right here.
Because the farmers can grow it without fear, they grow it with care. Because they grow it with care, the fruit is excellent. That chain is what supports the world of Okinawan acerola today.
1999 — The Day “Okinawan Acerola Day” Was Born
In 1999, the Motobu Town office and chamber of commerce, among others, designated May 12 as “Acerola Day,” timed to the start of the first harvest of the year.
From that same year, Tetsuko has continued to donate acerola jelly, free of charge, to the school lunches of every elementary and junior high school in Motobu Town. Today, recognition among Motobu children is 100%. For children born in Motobu, acerola is now a hometown flavor they have known since before they could form memories.
And in 2015, “Acerola Frozen” by Acerola Fresh won first place in the nationwide “Local Snack Ranking of Japan” — the first grand prize for Okinawa Prefecture. The moment the seeds the couple had planted spread across the entire country.
Come to Senaga Island and Try Okinawan Acerola
At SEE THE SEA, we serve menu items made with Okinawan-grown acerola.
The glass you drink on a terrace overlooking the Kerama Islands contains the trees pruned in the shape of a donut, the Okinawan sun, and sixty years of a couple who refused to give up. You don’t need to know the nutrition. You don’t need to know the history. If you take one sip and feel “this is good,” that is enough.
But — if, after you have finished, you happen to remember this article — the meaning of that tartness might change, just a little.
Reflecting on the Acerola Series
Frequently Asked Questions
- Why are acerola trees pruned into a "donut" shape?
- The "donut" pruning style opens the center of the tree and spreads branches outward, ensuring sunlight reaches the interior evenly and creating clear pathways for harvest work. It maximizes the fruit's sweetness and nutrition while minimizing typhoon damage.
- What is the difference between tree-ripened Okinawan acerola and typical acerola?
- Tree-ripened fruit is hand-picked the moment it turns red on the branch, preserving the maximum levels of vitamin C and polyphenols. In contrast, much overseas acerola is harvested unripe and ripens during shipping, leading to significant nutrient loss. Okinawa is one of the few regions where "tree-ripened" acerola can be selected.
- What makes the acerola drinks at SEE THE SEA special?
- We use tree-ripened acerola from Motobu Town, Okinawa, with no added sugar, no flavoring, and minimal processing. A seasonal menu that captures the grower's story, the nutrition, and the Okinawan sun — all in one glass.
