 In 1894, the Kōbu Railway, predecessor of the present-day Chūō Line, extended its existing railway line between Shinjuku and Tachikawa to Ushigome and opened Yotsuya and Shinanomachi stations.The railway enabled the easy transport of raw materials into the area; soon, pencil, tobacco and other industries moved in and began Yotsuya's rapid industrial development.Many historic temples and graves are located in Yotsuya.
