Moreover, despite the line’s name, some trains only go between Kanagawa and Shinjuku, without continuing to Saitama. Beside

The Saikyō Line was notorious for having the highest reported number of groping-related incidents (known as chikan incidents) in the Greater Tokyo area. This problem was directly addressed by introducing women-only passenger cars during rush hours, and indirectly addressed by reducing overcrowding problems as

185-535: A result, the construction standards of Line 6 were based on those of Tobu and Tokyu (such as 1,067 mm ( 3 ft 6 in ) gauge track and 20-meter-long cars - today, the Mita Line is the only Toei line to use this gauge). A depot was planned at Shimura, independent of the Nishi-Magome depot on Line 1. However, both Tokyu and Tobu decided the following year to operate their thorough services with

The portion between Ikebukuro and Akabane is officially known as the Akabane Line (Japanese: 赤羽線 ). For most purposes, JR refers to all of these as part of the "Saikyō Line" when being used for Saikyō Line services. There are three types of trains on the Saikyō Line: "Local" ( 各駅停車 , Kakueki-Teisha ) , "Rapid" ( 快速 , kaisoku ) , and "Commuter Rapid" ( 通勤快速 , tsūkin kaisoku ) . Between Akabane and Musashi-Urawa, Rapid trains stop only at Toda-Kōen, while Commuter Rapid trains, which run during rush hours, stop only at Musashi-Urawa between Akabane and Ōmiya.

777-604: The Rinkai Line began on 1 December 2002. The Saikyo Line has had a particularly severe problem of overcrowding during peak periods, especially during weekday mornings. The opening of the Shonan-Shinjuku Line in 2004 and the Tokyo Metro Fukutoshin Line in 2008, both of which parallel the Saikyō Line for part of its route, alleviated some of the worst crowding. Problems resulting from overcrowding have included
