April 23 is "Craft Beer Day," designated by the Japan Craft Beer Industry Liaison Council. Its origin lies in the enactment of Germany's Beer Purity Law on April 23, 1516. It is gradually becoming recognized among breweries and beer fans across the country as a day to once again reflect on ideas about ingredients and quality.

Setouchi Brewery is a brewery based in Takamatsu City, Kagawa Prefecture. On its official website, it states that it draws inspiration from the lifestyle and culture deeply connected to the Seto Inland Sea, the scenery of its islands, and its mild climate, and makes craft beer that reflects the appeal of the region. In addition to simply delivering products, it also focuses on contributing to the local community and on community events.

Brewery operations began in 2021, and since then it has produced more than 70 kinds of beer every year. From planning and design to brewing, packaging, and shipping, everything is handled in-house, and beyond its core products it also actively rolls out seasonal limited-edition releases. Their messaging around Craft Beer Day could also serve as an entry point to learning about the background of this kind of craftsmanship.
