Craft Ale Chigira, based in Kiryu City, Gunma Prefecture, has introduced a limited beer called "BERRY DOG DAY" on Instagram. The post adds, "Quantity is limited. Please take this chance," making it clear that availability is restricted.

Related public posts describe BERRY DOG DAY as a juicy Hazy IPA in the brewery’s style, brewed with seasonal blackberries and sake lees from Kondo Shuzo’s local "Akagiyama" sake. The beer is presented as a balance of ripe berry character and the gentle depth brought by the sake lees, rather than a fruit-forward beer that leans too far in one direction.

On its official website, Craft Ale Chigira presents itself as a brewery focused on easy-drinking American-style ales with citrusy hop aroma, and it regularly works across styles such as India, Hazy, Stout, and India Black Pale Ale. As a Kiryu brewery, it has built a profile that mixes local ingredients and regional brewing culture with beers that feel a little outside the usual lineup. BERRY DOG DAY fits neatly into that approach as another distinctive seasonal release.
