Miyashita Sake Brewery, based in Okayama City, produces and sells the Doppo and Kurashiki Beer craft beer lines. This announcement is tied to Ujo Summer Festival 2026, held across the Okayama Castle area.

The festival runs for two days, on Saturday, August 1 and Sunday, August 2, from 18:00 to 21:30. According to official event information, the site will include a gourmet area with local food stalls, a festival game area, and hands-on workshops for decorating wind chimes and handheld lanterns. The castle will also be lit up, with smoke and soap bubbles adding to the atmosphere.

Miyashita Sake Brewery appears in the gourmet area with Doppo. That places the brewery's beer alongside other local food and drink options in a setting shaped by the castle landscape and nighttime illumination. Admission is free, so visitors can easily combine the festival with a walk around the castle area.

The same season also brings Okayama Castle's summer illumination program, Natsu no Ujo Togenkyo. Taken together, the castle lights, local food, and craft beer make this a straightforward summer outing for both tourists and local residents.
