Chichibu Mainline

View of the line near Hirose-Yacho-no-Mori station

Chichibu Mainline (秩父本線, -honsen) is Chichibu Railway's only passenger line, linking Hanyu and Mitsumineguchi, both in Saitama Prefecture, Japan.

Locals living around the line call it the Chichibu sen, or Chichibu line. This is not to be confused with Seibu Railway's nearby Seibu Chichibu Line, which is almost always referred to in full to avoid ambiguities.
