“Like your favorite fruits, coffee beans preserve all the flavours; such as peach, blueberries, apples, or aroma of flowers. When I roast beans, I carefully direct the irreplaceable terroir, soil, varieties, environment and the idea of producers. I am pleased if my coffee provides colours to the people.”



After travelling to 80 countries around the world in his 20’s, Mr Sakata realised speciality coffee and its ecosystem had the potential to reduce poverty in developing countries. So he opened “KOTO COFFEE ROASTERS” in Nara in 2017, serving coffee and roasted beans.
