Hello, my name is Kunihiro Ohba. I am in charge of the process and keeping quality of teas. Organic teas that cultivated in nature are sometimes very individually unique. In order to keep the quality, we need to be well experienced. Although I am still growing as Tea Master, I am trying to make tea that always makes customers happy. I think that no matter how delicious tea is, the philosophy of the producers and the environment of the production area will be very important for customers’ satisfaction.
