In an Instagram post dated July 22, Rio Brewing Co. announced its participation in Matsudo Craft Beer Fest with Hashigo Sake. The event is scheduled for July 25 and 26 at the Matsudo Station West Exit Deck. The caption opens with the line "There's a battle that cannot be lost" and presents the weekend as a pride-filled matchup between Matsudo and Kashiwa.

Rio Brewing Co. is a brewery based in Kashiwa, Chiba. That local connection gives the announcement extra context: a brewery rooted in Kashiwa heading to a station-front event in neighboring Matsudo naturally carries a strong regional feel. The post also highlights Kashiwa's "spirit and momentum," while saying it looks forward to a friendly toast between Matsudo and Kashiwa.

The venue, Matsudo Station West Exit Deck, is easy to access and convenient for casual visitors passing through the area. The post does not specify the exact beers or sales format, but the setting itself is appealing for beer fans who want to enjoy craft beer in an open, walk-up-friendly urban space. For Rio Brewing Co., the weekend looks like a chance to bring its Kashiwa identity into a lively Matsudo crowd.
