Overview over the areas covered by the JR companies  (click to enlarge)

JR East Japan (JR Higashi Nihon) operates JR trains on the Japanese main island (Honshû) in the three regions Kantô, Yamanashi/Nagano/Niigata (referred to as the Kô-Shin-Etsu area (1)), and Tôhoku. The Kantô area has the city of Tôkyô at its centre and includes the Prefectures of Chiba (with the city of Chiba), Kanagawa (with the city of Yokohama), Saitama, Ibaraki, Tochigi and Gumma. The Tôkaidô Shinkansen from Shin Ôsaka in the west via Kyôto and Nagoya into Tôkyô, however, is operated by JR Tôkai. In Nagano Prefecture JR East Japan has borders with JR Tôkai. The Hokuriku Shinkansen is operated jointly by JR East Japan and JR West Japan, the territorial border being the station of Jôetsu Myôkô; personnel changes at Nagano. In the north the border between JR East Japan (1067 mm gauge) and JR Hokkaidô lies just north of Kanita at the Shin Naka-Oguni signal post; the Hokkaidô Shinkansen (1435 mm gauge), however, already starts at Shin Aomori.
