One single car was converted in February 1986 from former Iyo Railway 100 series car MoHa 106, purchased in October 1985.
This car was built in 1950 by Teikoku Sharyo as KuHa 405, and converted to become single-car MoHa 106 with an additional driving cab in 1961.
The second driving cab was subsequently taken out of use and a gangway door added, but from 1967, the driving cab was reinstated, with the gangway door left in place.

Conversion for use on the Choshi Electric Railway involved sealing the gangway in the later added cab end (at the Tokawa end), and replacement of the original Hitachi MIC bogies with Nippon Sharyo D-16 type bogies.

The car was repainted in 1990 from the earlier red and cream livery to the "new" Choshi Electric Railway livery of brown and red.

It was withdrawn after its final day of operation on 23 September 2010.
It was initially stored in the loop next to Tokawa Station before being moved to storage behind Kasagami-Kurohae Station.
From 1 May 2015, stored next to Tokawa Station, the car was used to house the Keiyo Towa Pharmaceutical Shōwa Nostalgia Museum, containing exhibits of toys from the Shōwa period (1925–1989).
