Kawaguchi Brewery is a brewpub in the east exit area of Kawaguchi Station. Its hallmark is that you can enjoy craft beer brewed in-house together with kiln-fired dishes and snacks, and it is known as a shop that carries Kawaguchi's "brewing culture" into the present day.

The representative house-brewed beers introduced by the shop are the fruity, easy-to-drink "Kawaguchi Onarimichi Ale," the "White Lily Weizen," which features the soft sweetness of wheat and a refreshing finish, and "Arakawa Sunset IPA," a beer with a well-balanced bitterness and citrus aroma. The lineup already conveys a sense of Kawaguchi from the names alone, and a side-by-side tasting makes the differences in style stand out clearly.

On the food side, the menu includes hot roast chicken, fragrant pork tonteki, and salads made with Saitama vegetables, all designed to pair well with beer. The interior is bright and offers counter seats, table seats, semi-private rooms, and sunken kotatsu seating, making it easy to use for anything from a quick solo drink to a relaxed tasting session with several people. It also accepts private reservations for around 50 people, giving it a strong presence as a casual local base for enjoying craft beer.
