Crowdsourced project to collect data on sake and sake breweries from across Japan, integrates lost historical data, and utilizes digital technology to establish stronger connections between producers and consumers.

Before World War II, Japan had 5,500 sake breweries. However, as of 2017, there were only about 1,500 remained, less than one-third of the original number. The top 13 sake breweries hold more than 50% of the market share, the rest are small breweries. With more beverage options like beer and wine available today, many small sake breweries face financial difficulties. With 20-50 citizens collaborating, this project aims to address this issue. It collects data on sake and sake breweries from across Japan, integrates lost historical data, and utilizes digital technology to establish stronger connections between producers and consumers. Additionally, it aims to preserve sake culture and pass down techniques of sake production, making the industry more sustainable. This project is still evolving through CfJ’s monthly hackathons. The main current challenge is how to take over and track unfinished tasks within the project.
