Like the Kobe-Takamatsu/Marugame route and Osaka-Takamatsu/Marugame route, tickets, coupon tickets, reservation and ticketing offices, and timetables are shared between private railway affiliates (Keihan Bus and Shikoku Express Bus) and JR affiliates (West JR Bus Company and JR Shikoku Bus Company).
神戸-高松・丸亀線や大阪-高松・丸亀線と同じく民鉄系（京阪バス・四国高速バス）と、JR系（西日本JRバス・JR四国バス）できっぷ・回数券の共通化、予約・発券場所の共通化、時刻表の共通化を行っている。
