Kengun Line

The line opened more than twenty years after the network's first sections, which had entered service on 1 August 1924. On 6 May 1945 the section between Suizenji — the stop now called Suizenji-kōen — and Mitsubishi-kōjō-mae ("in front of the Mitsubishi factory") was brought into service, and the Kuwamizu-machi, Kengun-kō-mae and Mitsubishi-kōjō-mae stops opened with it. Only weeks later, on 24 May 1945, the Sunatori stop was added along the route.

In March 1947 the Mitsubishi-kōjō-mae terminus was renamed Kengun-machi, the name it still carries. The route continued to gain stops: Shōgyō-kōkō-mae opened in 1950, Kengun-hashutsujo-mae on 20 May 1956, and Hatchō-baba on 16 April 1959. In 1958 the Sunatori stop was renamed Taiikukan-mae — later Shiritsu-taiikukan-mae — reflecting the gymnasium it served.

Further additions and renamings followed over the later twentieth century. On 1 April 1969 the Dōbutsuen-mae ("in front of the zoo") stop opened, and on 1 April 1992 it was renamed Dōshokubutsuen-mae ("in front of the zoological and botanical garden"). On 1 April 1995 the Kengun-hashutsujo-mae stop, named for a police box, was renamed Kengun-kōban-mae.

The twenty-first century brought a further round of stop renamings. On 1 March 2011 the Kuwamizu-bashi stop was renamed Kuwamizu-Shimin-byōin-mae, taking in the name of the nearby municipal hospital, and the Dōshokubutsuen-mae stop became Dōshokubutsuen-iriguchi. On 1 October 2019 the Kuwamizu-Shimin-byōin-mae stop was renamed once more, to Kuwamizu-kōsaten.

The line has nine stops, counting both termini, and is single-track only at the Kengun-machi stop. The network's two routes, A and B, both run over the whole line and continue by way of the Suizenji Line onto the trunk line through the city centre. Kengun-machi ranked third among the network's stops by average daily boardings in fiscal 2015, 2019 and 2023.
