The Higashiyama Line's color on maps is yellow and stations are labeled with the prefix "H".

Upon arrivals and departures at both Nagoya and Fujigaoka Stations, announcements are made in five languages: Japanese, English, Korean, Chinese, and Portuguese.

At first, the subway had six 100 series EMU trainsets, formed with two cars per set.

The line was simultaneously extended from Nagoya to Nakamura Kōen and from Hoshigaoka to its current eastern terminus of Fujigaoka on April 1, 1969.

The last remaining 5000 series train in service was withdrawn following a special final run on 30 August 2015.
