Takashi Yanase
Each station on the Asa Line features a cartoon mascot character designed by Takashi Yanase, a local cartoonist from Kōchi Prefecture. The mascot for Tōnohama Station is a figure dressed in the white pilgrim's garments and straw hat used by those on the Shikoku Pilgrimage. Named , the character is chosen because the station is located near the Kōnomine-ji, the 27th Buddhist temple on the pilgrim trail and many pilgrims use the station throughout the year.
