The trains represent the first use of aluminium body cars on Tōbu commuter trains. They are also the first Tōbu trains to feature bilingual (Japanese and English) automated passenger announcements.

The first 50000 series set, 51001, was delivered in November 2004 and entered service on the Tōbu Tōjō Line on 16 March 2005, followed by second-batch set 51002 in October 2005. The second set differs in having an emergency door in the front ends, and externally resembles the 50050 series used on the Tōbu Isesaki Line (see below).[1]
Two more sets, 51003 and 51004, were delivered during fiscal 2009.[2] 50003 was delivered to Shinrinkōen Depot in January 2010,[3] followed by 50004 in February 2010.[4] These two sets have pairs of opening windows and interiors based on sets 51061 onward.

The 10-car 50050 series sets were built for use on the Tōbu Isesaki and Nikkō lines, and inter-running services through the Tōkyō Metro Hanzōmon Line to the Tōkyū Den-en-toshi Line displacing the earlier 30000 series sets.[5]
The first set (51051) entered service on 18 March 2006, and as of January 2007, 10 sets were in service. While broadly based on the Tōjō Line 50000 series design with emergency end doors, cars are 30 mm narrower (2,770 mm compared with 2,800 mm) to cope with reduced clearances on the subway lines.
Sets 51061 onward have different seat covers and pairs of opening windows (like the 50090 series) instead of the large single-pane sealed windows on earlier units.
Two more sets (51066 to 51067) were delivered during fiscal 2009.[2]
| Year built | Set numbers | External features | Internal features |
|---|---|---|---|
| 2006 | 51051–51060 | Emergency end doors | |

The first set (51071) was delivered in early March 2007, entering revenue-earning service in July. It differs from earlier variants in having full-colour LED destination indicators, and is also equipped with ATO for subway operation.
A total of four sets were delivered by March 2008.[7]

Four 10-car 50090 sets were delivered in February and March 2008 for use on new Tōbu Tōjō Line limited-stop evening TJ Liner services starting from the start of the new timetable on 14 June 2008.[10] Internally, these trains feature rotating seats that can be arranged longitudinally for daytime services and in forward-facing transverse pairs for "Liner" services. These trains are also used on up "Rapid Express" services. Externally, the sets feature a blue waistline stripe running the length of each car, with a "TOJO LINE" logo.[11]
A public preview run of the 50090 series took place on 23 March 2008 from Ikebukuro to Shinrinkōen station, followed by a photographic event at Shinrinkōen depot.[12]
A fifth set, 51095, was delivered from Hitachi in September 2010,[13] followed by 51096 in November 2010, in preparation for an increase in the number of TJ Liner services from the start of the revised timetable on 5 March 2011.[14]
