Although the line technically begins at Fukuiguchi Station, all trains run through and terminate at Fukui Station. Trains run twice per hour during the day in order to connect with Hokuriku Main Line limited express trains. During morning peak hours between 7:00 and 9:00, three trains run per hour. There is a single Fukui-bound rapid train each morning, as well as a local "Mezamashi Train" (lit. "wake-up train") departing Mikuni-Minato at 5:16 every Monday morning that connects with Osaka and Nagoya-bound JR West limited express trains departing from Fukui Station.
All trains run under driver-only operation, but on-board female attendants sell and collect tickets, make station announcements, and assist passengers boarding and alighting. Doors are operated by the driver.
