Craft beer pub diagonal in Kofu, Yamanashi shared a tap-opening update on Instagram. The beer on tap is Nomcraft's "PUNKY DUCK," a West Coast IPA with an ABV of 6.5%. In the post, the bar describes it as a classic IPA with citrus aroma and a clean bitterness.

The beer is positioned as diagonal's 8th-anniversary beer, and the post also notes that it is the "final keg." That gives the release a special place in the bar's lineup, beyond a simple guest-beer update. For drinkers who like IPAs with a clear hop profile, bright citrus notes, and a dry, clean finish, this is an easy beer to read and appreciate.

Diagonal is a beer pub located in Naga Ryo Building in Aonuma, Kofu City. The bar's appeal lies in following changing taps and catching limited beers at the right moment. PUNKY DUCK fits that pattern well: a one-time tap moment that combines brewery identity, anniversary timing, and a style many hop-forward beer fans look for.

If you're tracking guest beers in Kofu, this is one to note. It is the kind of release that rewards people who enjoy a well-defined West Coast IPA and the atmosphere of a bar built around rotating taps.
