やなせたかし
Each station on the Asa Line features a cartoon mascot character designed by Takashi Yanase, a local cartoonist from Kōchi Prefecture. The mascot for Ioki Station is a figure dressed in a business suit and hat with a box for a head and holding a briefcase. His name is and is inspired by the character from the popular film series Otoko wa Tsurai yo. One title from the series about the traveling salesman Tora-san was to have been shot in Ioki for release in 1996 but was cancelled because of the death of the actor Kiyoshi Atsumi.
