Wikipedia Article About Fuji apple on Wikipedia Ranging in color from a light yellow-green with a bit of red to all red, the Fuji apple has a sweet and spicy flavor. The natural sweetness of the apple makes it a good candidate for applesauce because little sugar is required. The Fuji apple (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 the two American apple varieties, the Red Delicious and old Virginia Ralls Genet (sometimes cited as "Rawls Jennet") apples.
