About Ichijin-chan
"Ichijin-chan" was born as part of Ichijinsha Inc.'s 20th corporate anniversary campaign. Since the anniversary year kicked off on March 4, 2025, the character has been involved in various promotional activities to celebrate the milestone. The character's design was selected through an internal company submission, and the mascot costume is worn by an actual employee.
