Hop Kotan Brewing announced Night Walker alongside the start of its 2026 Harvest Brew season. Harvest Brew is the brewery's seasonal series built around brewing with fresh hops, and it remains one of the clearest expressions of the brewery's local identity.

Night Walker is a Black IPA with 6.0% ABV and 60 IBU. The beer aims for a dark appearance without heaviness. To shape the malt side, Hop Kotan uses a cold-steep method: Black Malt and Chocolate Malt are soaked in cold water to build color while reducing burnt, roasty astringency, leaving a subtle bittersweet chocolate note.

The hop bill is centered on Columbus and Simcoe, with Krush adding brightness. The brewery describes notes of dank resin, pine, stone fruit, and a dry, sharp bitterness that still finishes clean. The result is pitched as a beer that feels light enough for a late summer night while still leaving a firm hop impression.

Based in Kamifurano, Hokkaido, Hop Kotan Brewing works in a town known for commercial hop farming and produces more than 70 beers a year by combining local and overseas hops. Night Walker fits that approach well: rooted in place, but built with a modern hop profile. Distribution is expected to begin at selected bars and bottle shops as early as the coming weekend, with service also planned at the brewery's taproom, BEER KOTAN. An onboard sale on the JR Hokkaido Mankitsu Norokko train is scheduled for August 30.
