Created in 1998 by a staff member at the Suginami branch, Donpen was imagined as a penguin born in Antarctica and raised in Tokyo—a playful nod to the brand’s quirky, fun-loving image. His measurements are consistently noted as 98 (centimeters for height, weight, and even girth), and he’s known for his boundless energy and enthusiasm. His interests include exploring Don Quijote stores, night-walking, and even enjoying activities like fishing and engaging with social media trends.
