The Meitetsu 100 series (名鉄100系) is a commuter electric multiple unit type operated by Nagoya Railroad (Meitetsu) in Japan since 1978.

[1][2] In the 1950s, Toyota saw a surge in population thanks to its local car industry.

Despite this increase, no railway connected Toyota to Nagoya, forcing local residents to use cars.

The area around Nagoya suffered from frequent traffic congestions due to spike in automobile usage.

After a proposal in 1972 proposing around 139km of railway network around Nagoya including existing lines, Meitetsu gave away construction permits for the section between Yagoto and Akaike which was inherited from one of the railway companies Meitetsu absorbed to the Nagoya Municipal Subway, while also building the section between Akaike and Toyotashi Station.
