description Hassaku Overview

Hassaku (Citrus hassaku) is a citrus fruit discovered in Hiroshima Prefecture, Japan, around 1860. The fruit is distinguished by its large size—often comparable to a grapefruit—and its characteristic bittersweet flavor profile. Hassaku has a thick, somewhat rough rind that turns yellow-orange when ripe, with flesh that is moderately juicy with a distinctive taste combining sweetness and bitterness. The variety is primarily cultivated in Japan, particularly in the Setouchi region, and is commonly eaten fresh or used in processed foods and beverages.

Hassaku harvest occurs in late winter to early spring, making it a seasonal specialty in Japanese markets.
