At the beer pub "PUMP craft beer bar" in Minami-Ikebukuro, an early tap opening ahead of Trademark Brewing's tap takeover has begun. In a March 27 post, the bar announced that, with the event set for the following day, it had first tapped three kegs.

The three beers tapped in advance are all from Trademark Brewing (California, USA):

- One Louder (Pale Ale)
- Ocean Thunder (India Pale Ale)
- Puffers and Eels (Hazy IPA)

In addition, the previous day's lineup also included "Kin-Oni Pale Ale CGX Nelson" (Oni Densetsu / Hokkaido), making for a substantial selection even before the event begins.

On this day, PUMP also referred to the spring atmosphere of Minami-Ikebukuro, mentioning the cherry blossoms at nearby Homyoji Temple, and encouraged people to stop by casually and enjoy a cherry-blossom-viewing mood. Hours are Tuesday through Friday from 17:00 to 23:00, Saturday and Sunday from 15:00 to 23:00, with Mondays closed. Food L.O. is 22:00 and drink L.O. is 22:30. A beer flight that lets you compare four beers is also available, making it appealing to choose from the day’s lineup and taste them side by side.

The lineup mentioned that day also included Johana Beer's "Earl Grey (Herb Spice Ale)", West Coast Brewing's "The Technician (Funky Kettle Sour)", Mojiko Retro Beer's "Weizen \"Weizen\"", Societe Brewing's "The Coachman (Session IPA)", Georgetown Brewing's "Lucille IPA", Ise Kadoya Beer's "Neko no Nomimono \"Something for Cats\" (Hazy IPA)", and Karl Strauss Brewing's "Golden Stout". Within PUMP's distinctly international tap selection, the question is how the three Trademark Brewing kegs will be slotted in.
