Sakurada Gate

Sakuradamon, the southwestern gate of the Tokyo Imperial Palace's outer moat, is a tile-roofed masugata, or square-enclosure structure, of the kind common to Edo Castle's defensive perimeter. The site is associated with the 1860 Sakuradamon Incident, the assassination of tairō Ii Naosuke by anti-shogunate samurai, an event that helped accelerate the collapse of the Tokugawa order. Hiratsuka's print would foreground the gate's heavy timber framing, plastered walls, and hipped tile roof as a study in mass and silhouette, qualities suited to his bold black-and-white mokuhanga style. He frequently returned to historic architectural subjects in Tokyo and Kyoto, treating them as monumental forms abstracted from period detail. The handling of the tile roof in particular gave Hiratsuka room for the rhythmic carving he favored, with each tile reduced to a unit of repeating graphic notation across the printed surface.
