History
Makuharihongō Station (JB 34 / KS 52) is jointly operated by JR East and Keisei Electric Railway in Makuhari-Hongō 1-chōme, Hanamigawa-ku, Chiba City. The JR side opened on 1 October 1981 — the same day the Sōbu Main Line quadruple track was extended to Chiba — and only the Sōbu Line local trains stop there. The Keisei side, with its slightly different name 'Keisei Makuhari-Hongō', opened on 7 August 1991 on the Keisei Chiba Line, immediately south of and connected to the JR station. This makes Makuhari-Hongō one of just five points where JR and Keisei share a station building (the others being Nippori, Airport Terminal 2, Narita Airport, and Higashi-Matsudo) — and the only such interchange between the Sōbu Main Line and Keisei's parallel main lines.

Notes
During weekday rush hour, the No. 1 bus stop hosts a famous queue for the express 'Maku-01' connector to Makuhari New City (海浜幕張) — the line of waiting passengers regularly snakes back to the police box, and on busy days extends right to the JR ticket gate; a temporary ticket gate is even set up at peak times.
