The Nankai 12000 series (南海12000系?) is an electric multiple unit (EMU) train type operated by the Nankai Electric Railway in Japan on Southern Premium limited express services between Namba and Wakayamashi since 1 September 2011.[1] Two 4-car trainsets were delivered, replacing the older 10000 series sets.[2]


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.[3]

Passenger seats are 460 mm wide, 25 mm wider than in previous trains, and AC power outlets are provided.[3]


The sets are formed as follows.[1]

Designation Mc1 T1 T2 Mc2
Numbering MoHa 12000 SaHa 12800 SaHa 12850 MoHa 12100
Weight (t) 41.5 30.5 32.0 40.5
Seating capacity 60 68 64 50

The two end cars are each fitted with one PT7144-B single-arm pantograph.[1]


The first two 4-car sets were delivered from the Tokyu Car Corporation (now Japan Transport Engineering Company) factory in Yokohama in February 2011.[4]
