History
Iriya Station opened on 28 March 1961 in Taitō, Tokyo, as an underground stop on the new Hibiya Line, then operated by the Teito Rapid Transit Authority (TRTA). The line was extended through stages during the early 1960s, and Iriya — 4.1 km from the line's northern terminus at Kita-Senju — became a busy local stop in a dense neighbourhood squeezed between Ueno and the historical Yoshiwara entertainment district. The station has two opposed side platforms serving two tracks, with station number H-19. TRTA was privatised on 1 April 2004, and the station passed to its successor, Tokyo Metro, which operates it today.

Notes
Iriya neighbours the JR Yamanote Line's Uguisudani Station overground, and is a few minutes' walk from the Yoshiwara district — historically the most famous of Edo-era licensed pleasure quarters, abolished only in 1958, three years before the metro station opened.
