The Fuji apple ( ふじ Fuji、ふじりんご Fuji ringo) is an apple cultivar developed by growers at the Tohoku Research Station in Morioka, Japan in the late 1930s and brought to market in 1962. It is a cross between two American apple varieties, the Red Delicious and old Virginia Ralls Genet (sometimes cited as "Rawls Jennet") apples.
Fuji apples are typically large or very large and round, on average the size of a baseball. They contain between 9-11% sugars by weight and have a dense flesh that is sweeter and crispier than many other apple varieties, making them popular with consumers around the world. Fuji apples also have a very long shelf life compared to other apples, even without refrigeration. With refrigeration, Fuji apples can last up to 5-6 months.
