His prints covered a wide variety of genres; amongst his best known are his Yokohama-e pictures of foreigners in Yokohama in the 1860s, a period when he was a best-selling artist.
[7] In the 1859 to 1862[2] Sadahide produced a large number of Yokohama-e prints of foreigners and the goods they brought to Japan after the country ended its self-imposed isolation in 1854.
[1] While there is scant evidence of the reception of these works, the number of extant copies suggests they were popular, and they appear to depict foreigners in a positive light.
This in contrast to the philosophy of sonnō jōi ("revere the Emperor, expel the barbarians") that had gained currency since the Convention of Kanagawa of 1854.
There Sadahide made a panorama that was 10 metres (33 ft) long and produced books on the history and geography of Western lands.
[1][11] The first exhibition dedicated to Sadahide's work was held in 1997, subtitled The ukiyo-e artist who flies in the sky (空飛ぶ浮世絵師 Sora tobu ukiyo-e-shi).
