History
The Tokyo Monorail platforms at Hamamatsuchō opened on 17 September 1964 as the city-side terminus of the Tokyo Monorail Haneda Airport Line, built to ferry visitors to that year's Olympic Games. The connecting JR (then JNR) station next door had been in service since 16 December 1909 as a stop on the elevated Tōkaidō Main Line section between Shinagawa and Karasumori. In November 1965 the Tokyo Monorail company funded a new south ticket gate and an inter-station footbridge linking the two platforms, and a 90-metre platform extension followed in September 1974.

Notes
Tokyo Monorail funded the inter-station footbridge and the JR south gate itself in November 1965, paying the full cost so passengers could change between the two services without leaving paid area.
