Awaji Island Onions

Famed across Japan, Awaji Island onions are renowned for their delightful sweetness and tender texture. The aroma of these onions fills the air throughout Awaji Island during the harvesting season. Not just limited to culinary purposes, these onions have also become sought-after souvenirs, contributing to dishes like soups, snacks, and seasonings.

The History Awaji Island Onions

Onions, recognized as one of the earliest cultivated plants, were introduced to Japan towards the latter part of the Edo period (1603-1868). Initially prized for their ornamental qualities rather than their culinary use, onion seeds were brought to Awaji Island in 1888. In the subsequent 130 years, the island gradually emerged as a significant producer of onions.

Benefits of Awaji Island Onions

Allyl Sulfide

Allyl sulfide, accountable for the distinctive aroma and pungency of onions, offers notable blood-thinning qualities that contribute to preventing conditions like high blood pressure, arteriosclerosis, cerebral and myocardial infarctions. Its ability to regulate blood sugar levels makes it particularly beneficial for individuals with elevated cholesterol levels or those prone to diabetes. This compound’s robust bactericidal attributes aid in battling pathogens and managing viruses, including those causing colds and influenza.


Quercetin, a type of polyphenol, operates as an antioxidant by neutralizing active oxygen. Its efficacy extends to preventing wrinkles, aging, colds related to weakened immunity, and even cancer. This compound contributes to safeguarding eyes against strain-induced aging, regulating blood pressure, enhancing liver function, and addressing metabolic syndrome.


Potassium plays a pivotal role in reducing edema by facilitating the removal of surplus water and salt from the body. When combined with vitamin B1, it optimizes the recuperation process from fatigue. The synergy of potassium and vitamin B1 results in an effective reduction of fatigue and edema through the elimination of excess water and salt from the body.

Distinctive Traits of Awaji Island Onions

Awaji Island onions captivate with their irresistible sweetness, a gift of the island’s abundant sunlight and mineral-rich soil. Thanks to these exceptional growing conditions, these onions are approximately 1.4 times sweeter than their regular counterparts. Their elevated moisture content renders them tender and less pungent, rendering them perfect for raw consumption, particularly in salads.
