Meitetsu Toyokawa Line

The line was constructed during the Pacific War in 1945 to carry commuters to the Toyokawa Naval Arsenal. The construction materials were taken from lines suspended or converted into a single-track line, and the trains were also taken from existing lines.^[2] As the line was originally named Toyokawa Shinai Line (豊川市内線) and built with tram standards, the line is covered by the Tramways Act [ja].^[3] The section between Kō and Suwachō opened on 18 February 1945.^[4] However, the Toyokawa Naval Arsenal becomes defunct after air raids in August 1945. After the end of World War II, the line was started to be used by passengers to visit the Toyokawa Inari.^[2]

The voltage of the line was increased to 1,500 V in 1953. The line extended to Toyokawa-inari the next year.^[5] This extension made the Kozakai Branch Line [ja] branching from Ina to Kozakai redundant, which was closed at the same time. The area around Yawata Station was elevated in 1996.^[2]

As of 2025, trains service the station every 16-30 minutes from 5am to 11pm. Most services during daytime only runs inside the line, while services during rush hours provide through service to stations like Meitetsu Ichinomiya Station through the Nagoya Main Line.^[7]
