As part of its efforts to stop the problem of groping on commuter trains, East Japan Railway Co. announced Monday that it will introduce female-only cars on its Saikyo Line trains on an experimental basis next month.

JR East is the second railway to introduce such coaches following Keio Electric Railway.

According to JR East, one carriage on Saikyo Line trains, which link Tokyo's Ebisu Station with Kawagoe Station in Saitama Prefecture, will be female-only on Kawagoe-bound trains after 10 p.m. on weekdays.
