History
Heiwa-kōen opened on 25 December 1933 as Matsuyama-machi when the Nagasaki Electric Tramway Main Line was extended from the now-closed Shimo-no-Kawa to Ōhashi. The stop was the tramway's closest to the 9 August 1945 atomic-bomb hypocentre, and the Hamaguchi-machi – Ōhashi segment that contains it suffered the heaviest damage on the network; the line was restored on 16 May 1947. The platform layout was changed in 1961 to accommodate the type-360 cars, the canopy was replaced with a shelter on 19 February 2000, and on 1 August 2018 the stop took its current name after the adjacent Peace Park. It is stop number 19 on the Main Line.

Notes
On the 9 August anniversary of the atomic bombing the stop's normal flow is reversed — a ticket collector is posted on the platform so that passengers can also alight through the boarding door to ease crowding for the peace memorial ceremony.
