History
The Wakashio service commenced on 15 July 1972, using 183 series EMUs.[8] Evening Hometown Wakashio services for commuters were introduced from 16 March 1991, operating from Tokyo to Kazusa-Ichinomiya.[9] New 255 series EMUs were introduced from 2 July 1993, initially branded as View Wakashio.[9] Morning Oyaho Wakashio services for commuters were introduced from 3 December 1994, operating from Kazusa-Ichinomiya to Tokyo.[9] New E257-500 series EMUs were introduced from 16 October 2004, displacing the remaining 183 series trainsets.[2] From the start of the revised timetable on 10 December 2005, Wakashio services were made entirely no-smoking.[5]
The opening of the Tokyo Bay Aqua-Line road across the Tokyo Bay in 1997 saw increased competition from long-distance bus services offering cheaper fares, resulting in decreasing ridership figures on the Wakashio services.[10] From the start of the 15 March 2014 timetable revision, the number of services was reduced from 15 to 13 return workings daily.[10]
With the timetable revision on 16 March 2024, the number of Wakashio services is scheduled to reduce again and all remaining regular services will only operate as 5-car formations using E257 series trains. As a result, 9- and 10-car trainsets will cease to run on these services. In addition, services to/from Shinjuku will only operate on selected Saturdays and holidays.[4]
