BEER MARROW is a beer pub located on the 4th floor of the Kawada Building in Kichijoji Honcho, Musashino City, Tokyo. In an Instagram post on April 26, the shop shared that day's tap lineup along with its business notice. The post also noted that opening times vary by day, with the shop opening at 4 p.m., 5 p.m., or 6 p.m. depending on the date, and urged customers to check before visiting.

The lineup for the day consisted of 8 taps in total. Of those, 5 were specifically named: DD4D BREWING's sour IPA "Mag Mag" (5.0%), GAME BREW's golden ale "CONTINUE?" (4.0%), UCHU BREWING's DDH Hazy Imperial IPA "Foggy Dawn" (8.0%), Totopia Brewing's Oat Cream DIPA "Sirenphobia" (8.0%), and Inosu Beer's West Coast IPA "GSP one" (6.0%). Each beer was listed with its style and ABV, creating a lineup that ranged from a light golden ale to fuller-bodied hazy styles and a WC IPA with a distinct hop profile, offering a broad comparison tasting.

The remaining 3 taps were marked "Sorry, coming soon." and were still being prepared. In the shift from spring to early summer, it appears the bar will keep updating its lineup gradually, centering on sour IPAs, hazy styles, and IPAs. If you're looking for craft beer in Kichijoji, this is a spot worth checking for the latest tap status.
