Setouchi Brewery is a craft beer brand based in Takamatsu, Kagawa Prefecture, that handles everything in-house, from planning and brewing to shipping. Its directly operated "Riverside 351" is a taproom and shop next to the brewery, where you can enjoy eight draft beers and canned beer mainly on weekends. Guests are also welcome to bring food from outside, and it is presented as a casual place to stop by.

In its May Instagram post, the brewery announced five separate campaigns for the month.

- 5/1-6: Golden Week encore discount. Both pints and half pints get cheaper with each round, making it easier to add one more drink during the holiday break.
- 5/8-10: THANKS MOM. Bring your mother and receive one half pint free. Canned beer sets are also available for families living apart.
- 5/15-17: Cheers with nachos. A suggestion to enjoy the NEW RELEASE MEXICAN LAGER with nachos, designed as a first-drink recommendation.
- 5/22-24: UDON BREWING HALF TAP TAKE OVER. UDON BREWING takes over four taps and offers a lineup available only that weekend.
- 5/29-31: Keg Drain Festival. If a keg runs empty during a tap order, you will receive an original SETOUCHI BEER T-shirt.

What stands out about this post is that it is not just a simple new-product announcement, but a way of switching up the reason to visit each week. In a calm, Setouchi-style atmosphere, it was designed so people could enjoy the holiday break, family outings, food pairings, guest-brewery events, and even the moment a keg kicks. If you are following new releases and limited-time events in Takamatsu, Riverside 351 in May is one to watch.
