about us

The Hamadas have been involved in raising and packing Walla Walla River Sweet Onions for most of their lives. It all started in 1906 when Jikichi Hamada immigrated to the United States from Japan and started farming vegetables in the Seattle area. Jikichi and his family were relocated and confined to an internment camp during World War II. The farm was lost during the internment. After the war, the Jikichi settled in the Walla Walla Valley with his wife and seven sons and they began raising onion seed.

As the family grew, grandsons Randy & Barry learned how to raise Walla Walla River Sweet Onions from their father. Alan and Harry began their own farm in 1975. Brian, another grandson, has been raising Walla Walla River Sweet Onions since 1984.

It has been over sixty years since the Hamada family started a new life in the beautiful Walla Walla Valley, and their Walla Walla River Sweet Onion tradition continues today…

about the walla walla river sweet onion

Walla Walla Sweet Onions have a distinctly different flavor — milder and sweeter — than any other onion. Generations of selective cultivation and the perfect combination of climate and volcanic soil low in sulphur compounds (that give ordinary onions their harsh bite) work in synergy to produce the world’s sweetest onion. These onions are round with an elongated neck and dry, paper-thin skin. They tend to be larger in size, weighing up to two pounds. Walla Walla Sweets are a good source of Vitamin C, are sodium and cholesterol free, and are low in calories!

Walla Walla Sweet Onions are best when eaten raw or only slightly cooked. The natural juices allow these naturally sweet onions to cook rapidly, so they should be used to enhance foods where they can be quickly sauteed or grilled.

how to find walla walla river sweet onions in southern california

Walla Walla River Sweet Onions are an artisan product, hand-harvested, and only available for a short time once a year. But that doesn’t mean they’re hard to find!

Walla Walla Sweet Onions are harvested from June to September, and the first batch makes their way down to stores around mid-June.

They’ll know whether they’re receiving a shipment of Walla Wallas and when they’re due to arrive. Our popular Walla Wallas are usually stocked by all major supermarkets, but if they’re not in your store – now’s the time to ask for them! Produce managers always want to know how to serve their customers better.

You can tell the difference just by looking. Generic sweet onions are smaller looking. Walla Walla Sweet Onions are big, plump, magnificent onions. But just in case… look for the Genuine Walla Walla Sweet Onion sticker – our badge of honor!
