ITOENNorthAmerica Brand Guide

ITO EN North America: Brand Overview and History

ITO EN North America is the US arm of ITO EN, a pioneering Japanese company founded in 1966. Starting as a tea blending operation in Shizuoka, Japan—known as the tea capital—ITO EN revolutionized the industry by introducing ready-to-drink (RTD) green teas in the 1990s. Their flagship Oi Ocha, launched in 1991, became Japan's top-selling green tea brand, capturing the essence of freshly brewed sencha without added sugars or preservatives. Expanding to North America in the early 2000s, ITO EN North America now offers a curated selection of teas in bottles, cans, and tea bags, making authentic Japanese flavors accessible. Committed to sustainability, they source leaves from trusted Japanese farms and use PET bottles made from 100% recycled materials. Today, ITO EN stands as a leader in the Grocery & Gourmet Food > Beverages > Tea categories, particularly Iced Tea, Green Tea, and Matcha.
