diagonal, a beer pub in Kofu, Yamanashi, posted an Instagram reel under its "Beer Geek on Packet" series featuring Atsumi Peninsula Brewing. While the caption is brief, the video makes the theme clear: shelves and fridge doors packed with cans, giving a direct look at the bar's beer selection.

The footage highlights diagonal's lived-in, beer-geek-friendly atmosphere. Wood-paneled walls, posters, and stickers fill the frame, while the refrigerated cases show a mix of cans. One can is marked `PILS`, and another visible beer is Honolulu Beerworks' `Kewalo's Cream Ale`, suggesting a lineup that ranges from classic easy-drinking styles to more characterful imports and guest picks.

Atsumi Peninsula Brewing, based on the Atsumi Peninsula in Aichi, is the brewery named in the post. diagonal's "Beer Geek on Packet" format has become a way to introduce breweries one by one, and this update fits that approach well: a careful look at the shelves, the brewery, and the kind of beers a beer pub regular would want to explore.
