Jun Sato

Jun Sato is the head sake brewer at Reigen Fermentation in Berlin-Wedding. Originally from Koriyama in Fukushima Prefecture, Japan, he studied Economics at Nihon University in Tokyo before discovering his passion for traditional sake brewing. At the renowned Terada Honke Brewery in Chiba, Jun worked across all stages of the brewing process and eventually became responsible for Koji making – one of the most crucial and demanding roles in the brewery. There, he produced around 500 kilograms of Koji per week, forming the essential base for high-quality sake. Sake is traditionally brewed only during the winter months from October to March; between brewing seasons, Jun first came to Berlin to support the emerging project Reigen Fermentation. Inspired by the collaboration, he later decided to settle permanently in Berlin and dedicate himself fully to Reigen. Today, Jun Sato brings together Japanese craftsmanship, technical precision, and creative experimentation to shape the distinctive character of Reigen’s Berlin-made sake.
