Choshi Beer is a craft brewery based in Choshi, Chiba. On its official site, the brewery describes its theme as making beer that pairs well with Choshi's fish, linking its products closely with local food and place. This new project extends that local-focused approach into a collaboration with the city's official character, Chopi.

According to the Instagram post, the Chopi-label beers are scheduled for release on June 26. Before that, they will be sold in advance on June 21 at the Choshi Melon Festa in Inubosaki Terrace. Sales are limited to two locations: Inubosaki Terrace and Choshi Beer's Choshi Good Beer Cafe at the Tobei Brewery.

The lineup consists of three beers, all priced including tax:

- One for All SMaSH!!!! 700 yen
- Choshi Ale 700 yen
- All for One 800 yen

The post presents them as Choshi-only products for visitors, making them a straightforward local souvenir option tied to a city event.
