In an Instagram post, ISANA Brewing announced that its collaboration beer with THREE ARROWS BREWING had been tapped. The new release is "Pink Whale." According to the post, the style is Berliner Weisse and the alcohol content is 3.5%. It uses fruit from a blueberry farm in Fuchu, and is designed with blueberry and lime to create a vivid pink beer.

On the brewing side, crushed graham biscuits were used as an idea from the ISANA team. The goal was to add toasted aroma and a richer mouthfeel, creating a more layered beer that does not end with just a bright acidity. With its low alcohol content, it is easy to keep drinking, and it suits outdoor events in early spring.

For March 15, the announcement listed serving at the ISANA Brewing taproom, which is open from 12:30 to 21:00, as well as at "Inagi no Tobira Vol. 8" in Inagi-Naganuma, from 10:00 to 17:00. It also says the same beer will be available at the THREE ARROWS BREWING booth.

ISANA Brewing operates a "brewery & roastery" in Akishima, Tokyo. Its official website says it has been operating since May 2018 and brews using deep underground water from Akishima. This release, which connects local ingredients with collaboration among nearby breweries, seems to align naturally with the brewery's approach.
