The Hokusō Line (北総線, Hokusō-sen) is a commuter rail line operated by the third-sector Hokusō Railway (controlled by the Keisei Electric Railway) in Japan. It runs between Keisei-Takasago Station in Katsushika, Tokyo and Imba Nihon-idai Station in Inzai, Chiba. It is part of the primary Keisei route between central Tokyo and Narita International Airport through the Narita Sky Access Line. It uses the ATS Type 1 system. The line's name is derived from its route through the former Shimōsa Province, which is also known as "Hokusō".
