The Centre for Finance, Technology and Economics at Keio (FinTEK) (Director: Teruo Nakatsuma) and the Center for Social Innovation in Market Design (SIMDI) (Director: Morimitsu Kurino), both affiliated with the Institute of Economic Studies, the Faculty of Economics, Keio University, the Institute of Brewing and Fermentation (Director: Tsukasa Matsuda) at Fukushima University and Kinsuisho Sake Brewery Co. Ltd. will start a food chain verification study that covers the process from brewing to sales, in which sake from a damaged brewery will be used to brew aged sake at a new brewery. This will allow them to inherit the history and spirit of the old brewery and promote sales by adding one-of-a-kind value to the sake.
