Produced in Japan for Kirin Brewery Co in 1981 and released in 1990, Toyomidori has since been largely discontinued due to problems with downy mildew. It was developed alongside Kitamidori and Eastern Gold as a high alpha variety but was the least successful of the three in this respect.

Toyomidori is a cross between Northern Brewer and a Wye male and is also the parent of Azacca.
