A moonlit woodblock print from Hiroshige's Kisokaidō series, depicting travellers crossing a bridge at Nagakubo station.

Nagakubo is the twenty-eighth station in the series The Sixty-nine Stations of the Kisokaidō. This series was a collaborative project between Utagawa Hiroshige and Keisai Eisen, produced between 1835 and 1838. Hiroshige designed this specific print, which is often cited as one of the most successful compositions in the set. The image depicts a moonlit evening at the Nagakubo station, a location in the mountainous interior of Japan. The composition focuses on a large wooden bridge spanning the Wada River. Silhouetted figures of travellers and a packhorse cross the bridge, their dark forms contrasting with the pale light of a full moon. In the foreground, Hiroshige includes observational details that provide a sense of daily life. Children play with a dog on the riverbank while a groom leads a horse toward a nearby building. The use of bokashi, a hand-applied colour gradation technique, in the sky and water creates a sense of atmosphere. Hiroshige was known for his ability to capture specific weather conditions and times of day. In this print, the cool blue tones and the sharp silhouettes define the nocturnal setting. The dark shapes of the pine trees frame the moon, directing the eye toward the distant mountains. This work is part of the transition in ukiyo-e from actor and courtesan portraits to landscape subjects. It reflects the popularity of domestic travel in Edo-period Japan. The technical execution of the woodblock print relies on multiple carved blocks. Each colour requires a separate block, and the alignment must be precise to maintain the clarity of the fine lines. The artist uses the natural grain of the wood to add texture to the water and sky. This print is a documented example of Hiroshige's landscape work.
