ITO EN started out as a specialist tea manufacturer. Not only is ITO EN Japan's top brand in the ready-to-drink green tea market, it is also Japan's No. 1 seller of tea leaves (including tea bags and instant tea products), a large proportion of which is marketed under the Oi Ocha brand. These products cater to the needs of a wide range of consumers, from those wanting a traditional kyusu (Japanese teapot)-infused tea, to those wanting the freshness of home-brewed tea combined with the convenience of a tea bag or instant tea.
     A range of tea types and flavors are included in the Tea leaves line-up, including teas from specific growing regions and harvest times. Oi Ocha tea leaves are renowned for their authenticity, naturalness, flavor and aroma, setting the standard for leaf green tea sold in Japan.
     Tea bag products and instant tea products are particularly convenient for making the perfect single cup of ryokucha or matcha-infused green tea as well as many other variations.
