About

Hassaku (Japanese: 八朔, pronounced [ha̠sːa̠kɯ̟]), Citrus hassaku, is a Japanese citrus hybrid between pomelo and mandarin, with pomelo-like characteristics. The original plant was discovered near the Mitsugon Jōdo temple in Innoshima, Hiroshima Prefecture, Japan.

How to grow it

In 1964, it was reported that hassaku cultivation in Japan exceeded 2,500 acres, mostly in the Hiroshima prefecture of its origin. However, during the 1960s, hassaku has been increasingly planted elsewhere.

Today, most hassaku is produced in Wakayama Prefecture, representing about 60% of the Japanese output.

Uses

An extraction from the young fruits has been used medically in skin care treatments for patients with atopic dermatitis.
