When the Tokugawa shogunate ended in 1868, Japanese leaders began rapidly transforming Tokyo into a modern capital resplendent with railroads, gas streetlights, and horse-drawn carriages. Upon returning to Tokyo following a six-year exile, self-trained artist Kobayashi Kiyochika set out to capture his new city using traditional and Western techniques. The 93 prints he created between 1876 and 1881 differ greatly from the traditionally colorful works that represented Japanese art previously. Kiyochika’s works are studies in light, capturing the city’s rapid changes at dawn and dusk. Now visitors to the Smithsonian’s Arthur M. Sackler Gallery can view approximately half of Kiyochika’s studies in the new exhibition “Kiyochika: Master of the Night.” Because even though the colors in each print appear dark and brooding, the curiosity they convey about the modern age seems more optimistic than somber. The exhibition is on view daily, 10 a.m. to 5:30 p.m., to July 27, at the Arthur M. Sackler Gallery, 1050 Independence Ave. SW. Free. (202) 633-4880. asia.si.edu.
