In late August 2026, Summit Store announced the launch of its seasonal autumn bakery lineup, headlined by the “Zakku! Saku! Donut,” which features a dual texture of egg and cream dough with an almond-flavored biscuit coating. Other seasonal offerings included chestnut danish, sweet potato paste bread, and various potato-themed items.

Following this, Mister Donut released its annual autumn “Satsumaimo Do” (sweet potato donut) series. This collection includes five varieties, such as the “Ishiyaki-imo Style,” designed to mimic roasted sweet potatoes, and the “Fragrant Crème Brûlée.” Feedback noted an improved intensity of sweet potato flavor compared to previous years.
