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. From the start of the 15 March 2014 timetable revision, the number of services was reduced to six return workings daily.
