• Shinjuku Line: Bakuroyokoyama ⇄ Morishita (Tokyo)

Hamachō Station opened on 21 December 1978 as a stop on the Toei Shinjuku Line. The station sits beneath Hamachō Park in Nihonbashi-Hamachō, with the ticket gates on basement level 1 and the platform on basement level 3 along a 510-metre-radius curve. Two single-track shield-bored tunnels were joined into a single island-platform chamber using the pipe-roof method, in which steel pipes about 1.2 metres across were hydraulically pushed into the ground above the running tunnels to support the soft soil while it was excavated — the reason the station is known as a "spectacle-shaped" shield station. During construction in 1976 workers unearthed Naumann elephant fossils near the worksite, catalogued as the Hamachō Specimen. PASMO IC cards were accepted from 18 March 2007.
