What is Oi Ocha?
Japanese tea has 1,200 years of history. It is also a history of development of a variety of types of tea, including for tea ceremony, using matcha powdered tea and sencha prepared with a kyusu (Japanese teapot). ITO EN developed the world’s first canned green tea and PET-bottled green tea as ready-to-drink products. Oi Ocha is the No. 1 brand of green tea drink that has been beloved in Japan for more than 30 years. The brand name, Oi Ocha, are typical words said when someone wants to enjoy tea with a person who is close to them, such as their family. We only use tea leaves produced in Japan and attach great importance to the aroma and taste that are similar to those of freshly brewed tea from a kyusu. Oi Ocha has been recognized by Guinness World Records as the world's top selling brand of green tea drink.*
