The Semboku 12000 series (泉北12000系, Senboku 12000-kei) is a very similar train type, introduced by the private railway operator Semboku Rapid Railway, a former Nankai subsidiary, for use on Semboku Liner limited express services in Osaka Prefecture. One 4-car trainset was delivered in 2016 and entered revenue service on 27 January 2017.
Design
The new trains feature "Plasmacluster" air-purification technology developed by Sharp Corporation, representing the first use in a private operator (i.e. non-JR) train in Japan.[5]
Passenger seats are 460 mm (18 in) wide, 25 mm (0.98 in) wider than in previous trains, and AC power outlets are provided.[5]
The Semboku 12000 series is similar, but sports a gold livery and has different coloured seat covers in each of the four cars.[6]
Operations
The Nankai 12000 series is primarily used on Southern limited express services operating between Namba on the Nankai Main Line and Wakayamakō or Wakayamashi on the Wakayamakō Line. Its introduction allowed for all Southern services to offer reserved seating.[7]
The Semboku 12000 series was developed for use on Semboku Liner limited express services operating between Namba and Izumi-Chūō, via the Nankai Main Line, Kōya Line, and Semboku Line (Semboku Rapid Railway Line prior to April 2025[8]).[6]
The two train types are also able to operate interchangeably when needed.[9]

Formation
As of 1 April 2016[update], the fleet consists of two four-car sets, formed as follows, with two motored ("M") cars and two non-powered intermediate trailer ("T") cars, and car 1 at the Wakayamashi end.[3][10]

History
Two four-car sets were delivered from the Tokyu Car Corporation (now Japan Transport Engineering Company) factory in Yokohama in February 2011.[14] The trains entered service on 1 September 2011.[10]
Semboku Rapid Railway
Initial details of a new train on order for the Semboku Rapid Railway were announced in October 2016.[15] The four-car trainset, 12021, was delivered from the J-TREC factory in Yokohama to Wakayamashi in October 2016.[16]
On 21 January 2017, set 12021 was used on an invitation-only preview run between Kōmyōike and Namba.[17] The trainset entered revenue service on 27 January 2017, following an official send-off ceremony at Izumi-Chūō Station.[18]
On 10 May 2024, Semboku announced that the 12000 series would receive a redesigned livery.[19] It returned to service in the new livery on 30 May.[20]
Following the merger of the Semboku Rapid Railway into its parent company on 1 April 2025, the set became property of Nankai Electric Railway.[21]
