Innovator of Today's Most Popular Green Teas

Before 1738, only the wealthy had access to green tea. Everyone else brewed leaves in boiling water, resulting in a brown liquid with a slightly bitter taste. Kahei Yamamoto II wanted to make green tea accessible to everyone, and he learned that steaming tea leaves resulted in a delicious tea with a fresh yellow-green color, balanced sweetness, and a mild astringency that retains its vitamins and nutrients. This tea became an instant sensation, and made Yamamotoyama a household name.

Yamamotoyama’s culture of innovation continued with Kahei Yamamoto VI and the invention of gyokoro tea in 1835. Gyokuro is known as the highest quality tea with a dense, rich sweetness and astringency. Some who have tried it describe it as the green tea version of an espresso.

Kahei Yamamoto VIII saw the potential of nori and in 1947 began manufacturing and selling it as a holiday gift, which became immensely popular in Japan’s gift-giving culture. Like green tea, nori didn't remain a secret in Japan for long before becoming recognized world-wide for its taste and health benefits.

FieldsBy continually innovating while remaining true to tradition, each generation has cultivated a worldwide appreciation for the taste and health benefits of green tea and nori. Yamamotoyama values its heritage, remaining a family business committed to quality first throughout the centuries, while always improving and creating new products to meet the needs of generations to come.In order to provide quality green tea to people all over the world, Kahei Yamamoto IX searched the globe for optimal conditions before founding his own tea gardens outside San Paulo, Brazil, in 1970. In 1975, he established Yamamotoyama America in Los Angeles, CA, to process tea and nori to the highest standards for supermarkets and restaurants internationally. Through a long-term working relationship, Yamamotoyama acquired Portland, Oregon-based Stash Tea Company in 1993.
