A woodblock print by Utagawa Hiroshige depicting a summer firework display over the Sumida River and Ryogoku Bridge in Edo.

This woodblock print depicts the annual summer festival at Ryogoku Bridge in Edo, modern-day Tokyo. Utagawa Hiroshige captures the moment a single firework bursts above the Sumida River. The composition features a dark, atmospheric sky that contrasts with the pale orange of the falling sparks. Below, the river surface is crowded with various vessels, including small rowboats and larger roofed pleasure boats known as yanebune. The Ryogoku Bridge spans the right side of the image, its wooden pilings and structure rendered with precise lines. Figures are visible on the bridge and along the riverbanks, observing the display. Hiroshige uses a limited colour palette of indigo and grey tones to convey the evening atmosphere. The use of bokashi, a hand-applied gradation technique, is evident in the transition from the dark upper sky to the lighter horizon. This work is part of the series Famous Places in the Eastern Capital (Toto Meisho), published around 1831. It reflects the popular culture of the Edo period, where river outings and fireworks were central to summer leisure. The perspective is characteristic of Hiroshige's early style, combining traditional Japanese spatial arrangements with elements of Western linear perspective. The artist was born in Edo and became a master of the ukiyo-e tradition. He is known for his ability to capture weather conditions and light effects. In this print, the stillness of the water and the dark sky create a sense of quiet anticipation. The firework itself is not a large explosion but a delicate shower of light, which was typical of the pyrotechnics of the era. The Ryogoku area was a major entertainment district during the Edo period. The bridge was one of the few places where people from different social classes could gather. Hiroshige includes small details such as the lanterns on the boats and the silhouettes of the distant shore to provide a sense of scale.
