Kamiiida Line

The Kamiiida Line (上飯田線, Kamiiida-sen) is a subway line, part of the Nagoya Municipal Subway (名古屋市営地下鉄, Nagoya Shiei Chikatetsu) system in Nagoya, Japan. It runs between two stations, Kamiiida and Heian-dōri, both at Kita Ward, Nagoya. Both stations have automatic platform gates. The Kamiiida Line's color on maps is pink. Its stations carry the letter K followed by a number. Officially, the line is called Nagoya City Rapid Railway Line 7 (名古屋市高速度鉄道第7号線, Nagoya-shi Kōsokudo Tetsudō Dai-nana-gō-sen). All the stations accept manaca, a rechargeable contactless smart card. The line is essentially an extension of Meitetsu Komaki Line. As such, the two lines have through services.

After the abolishment of Nagoya Municipal Tramway in the 1970s, Kamiiida Station, the terminus of Meitetsu Komaki Line, lost its connection to other railway lines. Users had to walk to Heian-dōri Station or take a bus. The short, yet long-awaited link line was finally opened in 2003. There is a future plan to extend the line, but the plan is currently suspended.

This is technically the shortest subway line in the world if each line was separate from each other, at just 800 m between the two stations, as the Seibu Yurakucho Line in Tokyo is a bypass line with only one station to itself and cannot be called a subway line on its own. However, the function of this Kamiiida Line is a connection from the Meitetsu Komaki Line to the Nagoya Municipal Subway, hence the building of this <1km line.
