Trains run on the line for approximately 18 hours a day (from roughly 5:30 a.m. to 11:30 p.m.) and operate with a two-car formation every 30 minutes on average.

four-car formation through services to Nagoya Station via the Tōkaidō Main Line are operated every 15 minutes during peak hours.

Due to demands from passing municipalities and local residents, the line has gone through upgrades, including electrification in 2015.

It also had the oldest overpass bridge in the country near Handa Station before it was demolished and relocated in 2021.

[10][11] In response to this, JR Central began work in March 2010 to electrify the line.

[15] Construction to elevate the line around Handa Station began in 2020 and is expected to finish in 2026.

The proposed route would branch off from Okkawa Station and head west, connecting to the airport.

This route was estimated to take around 53 minutes if a rapid service were created between Nagoya Station and the airport, far slower than the opposing Meitetsu Tokoname Line extension proposal which was both cheaper and faster.

After the privatization of JNR, the line was transferred to Central Japan Railway Company.

[16][5] Currently, the line uses two types of electric multiple unit (EMU) trains manufactured by Nippon Sharyo after the electrification works.

313 series trains are used on the line in two-car formations operated by a single crew.

315 series trains are usually operated during rush hours in four-car formations on through services to Nagoya.
