SEE THE SEA select & resort is a café and select shop located at Umikaji Terrace on Senaga Island, Okinawa. We’d like to take a moment to share the story behind acerola — a fruit we use in our menu — its remarkable nutrition, and the land it comes from.
■ Not “Aserora” — It’s “Acerola”
Let’s start with the name. In Japan, the fruit is commonly written as “aserora” in Japanese — a shortened form. But its proper botanical name is Malpighia emarginata, and the people of Central and South America, where it originates, still call it acerola. We deliberately use the full name as a small gesture of respect — both for the fruit itself and for the people who have cultivated it for generations. It’s a minor detail, but we believe that’s exactly where the story of a thing lives.
■ The Real Story of Vitamin C
Acerola is famous for vitamin C — and rightly so. But few people know just how much it contains. According to Japan’s Standard Tables of Food Composition, 100 grams of sour-variety acerola contains approximately 1,700 mg of vitamin C. That’s roughly 17 times more than a whole lemon, and about 34 times more than lemon juice alone. Compared to orange, it’s approximately 28 times higher. The numbers are almost hard to believe. On top of that, acerola is rich in anthocyanins — a type of polyphenol — which work synergistically with vitamin C to deliver powerful antioxidant effects. This combination is exactly why it’s called a “superfruit.”
■ Why It Never Reaches You Fresh
Despite all this nutritional power, fresh acerola almost never appears on supermarket shelves across Japan. The reason is simple: the skin is so thin and delicate that the fruit begins to deteriorate within roughly three days of harvest. Refrigeration barely extends its life. It simply cannot survive the journey. That’s why acerola is typically distributed as juice, puree, or jelly. Looked at from the other direction, tasting fresh acerola is an experience you can only have in Okinawa — where it’s actually grown.
■ The Fact That It Can Only Grow Outdoors in Okinawa
Nearly all open-air acerola cultivation in Japan takes place in Okinawa Prefecture. The subtropical warmth, the intense sunlight, and the distinctive soil of Motobu — these conditions don’t exist together anywhere else in the country. Okinawa is considered the northernmost point on Earth where acerola can be naturally grown outdoors. When a traveler sips an acerola juice or smoothie in Okinawa, they’re drinking something that could only come from this specific place — from this climate, this soil, and the hands that tended the trees. All of that is folded into that vivid red color.
