Tetsu Kasuya is a Japanese barista and roaster, World Brewers Cup Champion 2016 (Dublin). He is the founder of Philocoffea, a roastery and café in Funabashi, Chiba, and serves as a Hario brand partner and educator.

He is best known as the creator of the 4:6 Method for the Hario V60 — a five-pour technique that splits the brew into a first 40% (controlling sweetness vs acidity through pour ratio) and a final 60% (controlling strength through the number of pours). The method has become one of the most replicated pour-over recipes in specialty coffee thanks to its clarity and how easy it is to adjust to taste.

His YouTube channel and books published in Japanese have brought the method, and his variants for the Hario Switch, Cafec dripper series, and Hario Mugen, to a worldwide audience.

Gota catalogues his recipes for V60, Hario Switch, Cafec, and Hario Mugen.
