History
The Takahama Line station at Ōtemachi opened on 3 April 1927 as 'Edomachi Station'. A separate stop on the trackside Ōtemachi Line opened on 1 May 1936, also as 'Edomachi'. On 1 July 1953 the two were renamed — the suburban-rail station became Ōtemachi Station and the tramway stop became Ōtemachi-Ekimae. The Ōtemachi-Ekimae stop received a safety zone before 1967. Today the suburban-line station carries number IY09 and the tramway stop carries number 04.

Notes
Ōtemachi is best known for its diamond crossing — a flat-grade rail intersection between the suburban high-floor train line and the street-level tramway. Once common nationwide, only this station and adjacent Kōmachi Station still have such a crossing in regular use anywhere in Japan.
