DONZO Brewing, a microbrewery in Kotohira, Kagawa, is launching a third-anniversary campaign. The brewery opened on June 17, 2023, and has built its taproom around both brewing and dining spaces in the town's Shinmachi shopping street. Its name comes from the nearby historic site "Donzoro," reflecting the brewery's goal of serving as a place where locals and travelers can gather.

The campaign begins the day after the brewery's anniversary.

- Dates: June 18, 2026 to June 22, 2026
- Offer: Half-price drinks
- Eligible items: DONZO original craft beers and soft drinks priced at 400 yen
- Beers included: Kotohira Kölsch, Kotohira IPA, Kotohira Pale Ale, and Shingu Tea Ale
- Note: Guests can order any number of qualifying drinks at the half-price rate

Outside the campaign period, DONZO Brewing serves six craft beers at a time, including beers made at the adjacent brewery. Its Kotohira Kölsch is described as a light beer with aromas reminiscent of white wine, making it one of the venue's most recognizable pours. The taproom also offers food, including the popular Donzo Dog, made with sausages sourced from a local butcher in the shopping street.

With limited menu items also planned for the anniversary period, the brewery is positioning the week as an easy way for both locals and visitors to experience its lineup in one visit.
