Hachiko Line

The Hachiko Line (八高線, -sen) is a 92 km regional railway line in the East Japan Railway Company system in Tokyo, Saitama, and Gunma Prefectures in Japan. Its endpoints are Hachioji Station in Hachioji and Kuragano Station in Takasaki, Gunma Prefecture. The line has a gauge of 1067 mm.

Komagawa Station in Hidaka, Saitama, divides the line into two pieces. The southern segment from Hachioji to Komagawa is electrified, operating at 1500 VDC. At Komagawa, some trains reverse direction for the return trip, while others enter the Kawagoe Line and continue to Kawagoe Station. A few trains leave the Hachiko Line at Haijima Station, entering the Ome Line and terminating at Tokyo Station.

The northern segment connects Komagawa with Kuragano, providing diesel service. All trains continue on the Takasaki Line to Takasaki Station, where transfer to the Joetsu Shinkansen is available. No through service connects the southern and northern halves of the line.

Japan Freight Railway Company also operates trains on the Hachiko Line.

The Hachiko Line takes the first kanji of its name from Hachioji (八王子) and the second from Takasaki (高崎).
