English: The old Ninomaru Second East Gate of Nagoya Castle, also called the East Iron Gate, was the outer gate of the Ninomaru enceinte on the east side. It was a square, box-like structure with two separate doors opening into and out of the enclosure. In 1963, the gate was dismantled and stored temporarily to make way for the construction of the Aichi Prefectural Gymnasium. In 1972, the gate was relocated to the side of the old Honmaru East Gate, where it stands today. The gate, built in the style of gates in ancient Korea, with a tile-covered slanting roof and plastered eaves, has iron-banded pillars, a crosspiece and doors.
