Chuo Line Beer Works is a brewery in Koganei, Tokyo, that officially promotes the message, "Beer that began at the station, building bridges to the town." It grew out of hop-growing activities led by local residents and station staff along the Chuo Line, and its taproom offers not only its own beers but also guest beers centered on the Tama area.

With that background in mind, this tap is more than just a new product announcement. It is an effort to turn the craft beer culture nurtured along the Chuo Line into a concrete, drinkable experience through collaboration with a neighboring brewery. It is a tap update worth paying attention to not only for those seeking the fruitiness and lightness typical of a Hazy IPA, but also for readers who want to savor the local context of the railway line itself.
