The Journey to the Creation of Juno Heart

Aomori Prefecture, a Producer of Cherries

Cherry cultivation in Aomori has flourished in tandem with apple cultivation, mainly because cherry trees were planted near apple trees as a windbreaker to protect the apples from the wind. As cherries are less susceptible to the effects of the cold seasonal wind “Yamase,” cultivation of cherries has progressed mainly in the southern region of Aomori Prefecture.

“Juno Heart” has been the subject of crossbreeding and breeding research since 1997 at the Aomori Prefectural Industrial Technology Center’s Apple Research Institute, located in Gonohe Town, Aomori Prefecture. Juno Heart is the result of crossing “Benishuho,” which has a strong reputation for sweetness and flavor, with “Summit,” which is native to Canada and has large fruit and flesh that easily detaches from the seed. Research focused to produce the desired color, size, and flavor.

In May 2005, a wildfire broke out in the vicinity of the Aomori Industrial Technology Center’s apple research center, resulting in a massive fire that destroyed more than 2/3 of the trees under its care. The fire came within three trees of the original trees, but thankfully they were unscathed. Since then, Juno Heart is known as the “lucky cherry.”

Although the lucky original tree has now completed its role in cultivating the variety, it still quietly blossoms and bears fruit every year in the Center’s Fruit Tree Department.

Given these accounts of lucky cherries, the name “Juno Heart” was coined by combining “Juno,” the Roman goddess of family happiness, and the fruit’s heart shape.

“Aomori Heart Beat”, the Best of Juno Heart

Among Juno Hearts, those that are 4L size or larger and are recognized by quality inspection as having “excellent coloring and heart shape” are sold under the name “Aomori Heart Beat,” the best of Juno Hearts.

At one of the first auction, the price per fruit reached 40,000 yen.
