Teenage Brewing, based in Tokigawa, Saitama, makes beers centered on IPA, sour ale, and sour IPA. The brewery will release Sonar Aid as a support beer for AMAKUSA SONAR BEER in Amakusa, Kumamoto, on August 15.

According to the Instagram post, 150 yen from each 350ml can sold, and from each 15L keg converted to 350ml units, will be donated to AMAKUSA SONAR BEER. The funds are meant to help restore brewing and business operations and support ongoing relief activity on the ground. The label uses both breweries' logos, turning the beer into a shared way for brewers, retailers, and drinkers to take part in the same cause.

Sonar Aid is a Juicy IPA with 7.0% ABV. It will be sold through Teenage Brewing's official online shop for regular customers and through its dedicated sales site for trade accounts. The post also says donation boxes and message boards will appear at selected venues, including Ofuro Cafe Utatane on August 15, BEERPUB KICK on August 16, and Craft Beer Market Jimbocho on August 29.
