The 521 series (521系?) is a dual-voltage AC/DC outer-suburban electric multiple unit (EMU) train type operated by West Japan Railway Company (JR West) on local services in the Fukui and Kanazawa areas since November 2006.
The 521 series was the first dual-voltage suburban EMU type to be built for JR West. The body of the first two batches was based on the 223-5000 series suburban EMU design, with the same WMT102C 230 kW traction motors. The sets are able to be used on wanman driver-only operation services.
- Hokuriku Main Line (Maibara - Toyama)
- Kosei Line (Ōmi-Imazu - Ōmi-Shiotsu)
- Obama Line (Tsuruga - Higashi-Maizuru, sometimes substituted for 125 series)
As of 1 April 2013, the fleet consists of 35 2-car sets, allocated to Kanazawa (15 sets, G01-G15) and Tsuruga (20 sets, E01-E05, M01-M15) depots.
A further 21 third-batch 2-car sets are scheduled to be delivered in fiscal 2013 (19 sets) and fiscal 2014 (2 sets), and the first three sets of this new batch were delivered to Tsuruga Depot in November 2013. The third-batch sets have cab ends based on the JR West 225 series EMUs, with improved crash resistance, and use LED lighting for interior lighting. These sets are scheduled to enter revenue service from spring 2014.

The first five sets, E01 to E05, were built by Kawasaki Heavy Industries and Kinki Sharyo, and were delivered to Fukui depot between September and October 2006. These entered revenue service from 30 November 2006. The fleet was reallocated to Tsuruga Depot from 1 June 2010.
Ten more sets, G01 to G10, built by Kinki Sharyo, were delivered to Kanazawa depot between October 2009 and March 2010, entering revenue service from 13 March 2010. A further five sets, G11 to G15, were delivered from Kawasaki Heavy Industries in December 2010 and January 2011. 15 more sets, M01 to M15, were delivered from Kawasaki Heavy Industries to Tsuruga Depot between January and March 2011.
16 two-car 521 series sets are scheduled to be transferred to the third-sector railway operating company Ainokaze Toyama Railway for use from March 2015 when JR West hands over ownership of the sections of the Hokuriku Main Line running parallel to the new Hokuriku Shinkansen.
