Japan’s most expensive fruits, from the legendary Yubari King melon to rare ghost strawberries
For most of us, fruit is an everyday pleasure—a mid-morning snack, a dessert option or something we toss into our shopping cart without much thought. But in the hallowed department stores of Tokyo and the climate-controlled orchards of rural Japan, fruit has transcended its humble origins to become something else entirely: edible art, social currency, investment-grade produce. Here, the pursuit of the perfect melon or flawless grape has created an industry where a single specimen can fetch prices more commonly associated with luxury items. These aren’t just expensive fruits—they’re monuments to obsessive cultivation and aesthetic perfection.
In case you missed it: 7 rare fruits from Asia that look absolutely otherworldly
Yubari King melon: the apex of melons
Grown exclusively in the volcanic ash soil of Yubari, Hokkaido, this hybrid of Earl’s Favourite and Burpee’s Spicy Cantaloupe represents the apex of melon cultivation. Farmers employ the “one branch, one fruit” method, ruthlessly pruning all other buds so the vine’s entire nutrient output feeds a single Yubari King melon. These expensive fruits are massaged with white gloves to ensure perfect spherical symmetry and even netting. In auctions, a pair can sell for ¥3 million (approximately US$19,000). The T-shaped stem isn’t decorative—it’s proof of pedigree and freshness.
Ruby Roman grapes: the ping-pong-ball-sized grapes
These ping-pong-ball-sized grapes from Ishikawa Prefecture are the world’s largest table grapes, each measuring at least 30 mm in diameter. To qualify as Ruby Roman, individual grapes must weigh a minimum of 20 grams and register over 18 per cent sugar content. The elusive premium class requires bunches exceeding 700 grams—in some years, zero bunches qualify. A single bunch of these expensive fruits have reportedly fetched ¥1.6 million (around US$10,000).
Densuke watermelon: the black pearl
A Hokkaido marvel, the Densuke watermelon is instantly recognisable by its solid, glossy, deep-green rind that appears jet black, completely devoid of standard watermelon stripes. The flesh delivers extraordinary crispness without the mealiness that plagues common varieties, with heightened sweetness that justifies its price. Limited to specific plots in Toma, up to 10,000 units emerge annually. The 2025 season yielded a ¥700,000 (around US$4,400) auction bid, whilst retail specimens command around US$250.

Taiyo no Tamago mango: the egg of the sun
Miyazaki Prefecture’s approach to mango cultivation is revolutionary: these expensive fruits are never picked. Farmers position nets beneath each mango, harvesting only after the fruit naturally detaches at peak ripeness. Qualifying Taiyo no Tamago mango specimens must weigh at least 350 grams, register 15 per cent sugar content and display perfect deep-red colouring across half the fruit. Premium pairs have reportedly sold for over US$4,000. The texture is often described as “edible silk”—zero fibrous strings, tasting of mango, pineapple and coconut blended into one.
White Jewel strawberry: the ghost berry
A Saga Prefecture creation, White Jewel strawberries represent cross-breeding as art. Bred to lack anthocyanin—which triggers red pigmentation—these strawberries remain pure white inside and out, even when fully ripe and sweet. Maintaining this ghostly appearance proves challenging; excessive sun exposure causes pink blemishes, meaning only around 10 per cent of harvests meet aesthetic standards. Individual berries nestle in jewellery-style boxes, selling for US$10 to US$40 each. They’re less fruit, more edible sculpture—a collector’s item that happens to taste sublime.
