The 8.9 km (5.5 mi) section of tramway track between Fukushima and Iizaka Station (present-day Hanamizuzaka) opened on 13 April 1923.

Izumi Station opened in 1940, and in the following years the section between Fukushima and Moriai (present-day Bijutsukantoshokanmae) was converted to dedicated tramway track.

[citation needed] In 1980 two more 5000 series cars were acquired from Tokyu, and two years later Iizaka Onsen Station was moved to coincide with the shortening of the line by 100 meters (330 ft).

[citation needed] 1991 saw multiple changes happen to the Iizaka Line, starting out with the renaming of Moriai to Bijutsukantoshokanmae.

The train continued past Soneda, the next station, and crashed through the buffer stop at Fukushima, the end of the line.

The train continued for 12 meters (39 ft) further, coming to rest in Fukushima Station's East Building.

[citation needed] It was later discovered that due to improper maintenance, the power outage at Bijutsukantoshokanmae had caused the main brakes to become nonfunctional.

As of 1 April 2016[update], services on the line were operated using a fleet of four two-car and two three-car 7000 series stainless steel electric multiple unit (EMU) trains converted from former Tokyu 7000 series EMUs.

[5] In 2017, a number of former Tokyu 1000 series cars were resold to Fukushima Transportation for use on the Iizaka Line.
