History
edit- 15 July 1972 - Sazanami service starts coinciding with opening of the underground Sōbu Line platforms at Tokyo Station.
- 16 March 1991 - Sazanami service are rerouted via the Keiyo Line from Tokyo.
- 2 July 1993 - 255 series EMUs are introduced on View Sazanami services from Tokyo to Chikura.
- 16 October 2004 - E257-500 series EMUs are introduced.
- 10 December 2005 - The View Sazanami name is discontinued, and all services are made entirely no-smoking.[4]
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 Sazanami services.[5] From the start of the 15 March 2014 timetable revision, the number of services was reduced to six return workings daily.[5]
