White Jewel strawberries were created four years ago, by Yasuhito Teshima, and his farm in Japan’s Saga Prefecture remains the only one in the world that produces this unique fruit. Teshima-san claims he spent years cross-breeding different types of strawberries and perfecting his growing technique in order to come up with a large strawberry that was white both on the inside and the outside.
One of the secrets to growing White Jewel strawberries is reduced exposure to sunlight, which reduces the level of anthocyanin, the natural chemical that gives fruits and vegetables their color. But Yasuhito Teshima says that even after years of trial and error, his technique is far from perfect. Only 10 percent of his strawberries turn out white, and only a few of these are perfectly pale, with the rest featuring red patches, or sporting a milky ping hue. Once fully developed, White Jewel strawberries will not turn red, even if exposed to direct sunlight.
Teshima acknowledges that his White Jewels have to compete against other types of white strawberries developed in Japan, but claims that his are considerably larger and whiter than any of the other breeds.
As you can imagine, a novelty fruit that is ultra rare and extremely difficult to produce can fetch a very high price, and the White Jewel strawberry is a perfect example. They are sold individually for $10, or in very small packs for $40. I don’t care where you live, that’s super expensive for a strawberry.
“The flavor is something deep, something that doesn’t have a huge impact, but it does give you a slightly mysterious feeling and finally, you understand it, and it is really, really tasty,” Teshima told Great Big Story.
John Daub, an expat living in Japan, got a chance to try White Jewel while visiting Teshima’s farm, and reports the following: “The Shiroi Houseki smells very sweet. The skin is very soft. The first bite is juicy with a initial taste like fresh pineapple—but that disappears after a couple of seconds. It gets sweet like candy. Not too overpowering. Unlike candy, the natural sugars don’t stay in your mouth and leaves a fresh aftertaste.”
Daub adds that in Japanese culture, rare and expensive fruit like the White Jewels are bought as special gifts, rather than just as a sweet snack.
Interestingly enough, White Jewels are not the most expensive Japanese strawberries. That title goes to Kokota strawberries, a rare breed of giant red strawberries that have “good acidity and rich sweetness”. They can sell for $22 apiece.
