Butterfly Brewery, a craft brewery and beer producer based in Kasugai, Aichi, has announced a limited souvenir-ticket offer tied to the stage production "Mubanso Sonata." Each ticket includes one of four beers inspired by the play’s “after-work beer” scene, with one beer provided per ticket.

The brewery notes that this format was also well received during the 2024 run of the production. By turning an on-stage image into an actual beer to take home, the collaboration extends the experience beyond the theater and gives audiences another way to remember the performance. Butterfly Brewery continues to operate as a local craft brewery in Kasugai, building connections between beer, place, and expression.

In the announcement, the brewery encourages audiences to enjoy the musical created by Caramel Box together with Butterfly Brewery’s beer. For theatergoers and beer fans alike, it is a straightforward but memorable collaboration that ties the atmosphere of the show to a tangible souvenir.
