Today, there are only four 762 mm (2 ft 6 in) gauge railway lines in operation in Japan.

However, this extension was sold off in 1927 to Ise Electric Railway (Iseden) for use as part of their main line.

Kintetsu developed a plan to straighten the Nagoya Line as well as enlarge Suwa Station, which would be moved about a kilometre to the west; construction began in 1952 and took several years to complete.

In August 2012, Kintetsu announced its wishes to close both the Utsube and Hachioji Lines, with plans to convert the trackbed into a dedicated bus route.

It has since been announced that Kintetsu would transfer the operation of these lines to the Yokkaichi City Government in 2015.

[1] As a consequence, Yokkaichi Asunarou Railway was incorporated and took control of the line as from April 1, 2015.
