ITO EN has been producing products from contract farming since 1976. To provide Japanese tea products tailored to each form of consumption from PET plastic bottles and tea leaves to tea bags by closely following the changing lifestyles and preferences of each customer, we have channeled our pride as Japan's leading tea producer through efforts that begin with the development of tea plantations (the production of raw ingredients).

Oi Ocha set the record for the highest green tea beverage sales in the world for 2018, and was recognized with a Guinness World Record in 2019
World No. 1
As it celebrated its 30th anniversary in 2019, the Oi Ocha brand was recognized and certified by Guinness World Records as the world’s biggest selling natural healthy RTD green tea brand (by retail value sales in the most recent year).
The Oi Ocha brand first went on sale as "Oi Ocha Green Tea" in February 1989, and in the years since has continued to develop variations to meet consumer preferences and drive innovation to adapt to the changing times, such as being the first in the world to launch green tea in PET plastic bottles. Oi Ocha will continue to respond to the changing times in the future, never forgetting the valued customers that helped cultivate the brand, and striving to make Japanese tea a loved and more familiar presence to consumers around the world.
First in the world
Developed the world's first PET bottled green tea beverage
First in the world
Discerning that PET plastic bottles would become a mainstream beverage container, ITO EN began considering commercializing Oi Ocha in plastic bottles. Sediment, known as Ori, became an issue in the product’s development. Sediment appears in large amounts within two to three days of green tea extraction, as components in the tea precipitate as floating particles. While not harmful to the body, it can look unpleasant in clear plastic bottles, and can cause some loss of flavor. ITO EN developed its Natural Clear production method after researching ways to maintain flavor while removing this sediment. By using natural microfilters to strain the tea, the company succeeded in preserving the original aroma and flavor of green tea, while bringing out its clear, green color. In 1996, a patent was obtained for this Natural Clear production method.

We started our business as a small green tea company in Japan in 1964. Since then, ITO EN has evolved into a global company developing and introducing innovative products to the market. In 1984, we pioneered the world's first canned green tea. This became our top selling brand "Oi Ocha", which today is distributed in some 40 countries and regions. With dedication to creating authentic and quality products, our portfolio has expanded beyond tea to include a variety of beverages that embody the company’s five principles of Natural, Safe, Healthy, Well-designed and Delicious.

Tea leaves
As a company deeply involved in agriculture, ITO EN launched the Tea-Producing Region Development Project in 1976 to achieve both the stable procurement of safe, secure and high quality green tea raw materials and solutions to the issues facing Japanese agriculture. This project consists of two different initiatives: cultivation under contract, whereby we purchase all tea leaves produced by contracted local tea farmers, and the new tea farms business, which involves creating large tea farms from abandoned farmland. The cultivated tea leaves are used as the ingredients for Oi Ocha products.
When promoting the overseas export of green tea and matcha, the quality standards of each country need to be met. That is why ITO EN has pursued the development of low-pesticide and organically-cultivated green tea and matcha ingredients that comply with the standards of various countries as part of efforts to increase export volume. The promotion of low-pesticide use and organic farming also helps to preserve biodiversity around tea producing regions. In addition, we have also worked with tea producers to acquire international certifications such as Rainforest Alliance Certification for some of the matcha ingredients in high demand overseas.
The Technology of "Roasting"
Oi Ocha uses a production process that makes the most of the characteristics of the tea leaves and brings out their best taste.The taste of tea is said to be determined by 'fire'. 'Fire' is the finishing process used to increase the aroma and flavour of the tea leaves. Roasting is similar to cooking Japanese food. Japanese food tries to bring out the best of the ingredients. Similarly, green tea is similarly roasted to bring out the best of the tea leaves and enrich their flavour.
Pursuit of Tastiness
ITO EN has been producing products from tea plantations since 1976. To provide Japanese tea products tailored to each form of consumption from PET plastic bottles and tea leaves to tea bags by closely following the changing lifestyles and preferences of each customer, we have channeled our pride as Japan's leading tea producer through efforts that begin with the development of tea plantations (the production of raw ingredients).
