Ogawa industrial

Our Story

Our family company, Ogawa Sangyo, was established in 1908. Our traditional methods of producing barley tea (mugicha) and soybean flour (kinako) have been preserved and passed down over four generations using the same traditional methods perfected over one hundred years ago. Tradition and culture run deep in our roots and in our family, and we are passionate about sharing our family’s products with the world.

After our founder, Takejiro Ogawa, lost his father in the war, he wanted to work hard to make his father proud. Thus, Takejiro started Ogawa Sangyo as a way to pass down family culture and tradition for generations to come, even after we are no longer present. Each generation has watched their parents labor day after day for long hours to protect and keep the taste of our products alive; as a means to tell our story and to share the love.

This labor of love has created our rich, unique tastes and our rich, unique history that we are proud to share with you all. We hope our products can be shared with you and your loved ones as you create your own history and family traditions.

Our signature barley tea

Our signature Tsubumaru barley tea, is characterized by its beautifully finished, translucent color, delicate taste and aroma. Even in the present age where many companies have switched to manufacturing efficiency, we continue to produce our products using the double roasting method over a traditional stone oven.

The meaning behind our barley tea’s name Tsubumaru comes from the tsubumaru method which prepares the barley without crushing them. It is less harsh and makes the tea more delicate as we continue to honor our traditional values and taste. The process is time-consuming, especially for a small family-run factory and business, but we believe that our dedication to time and taste makes the world of a difference in enjoying the beloved Japanese drink, mugicha.
