Almost nothing is known about the life of Nagashima Shungyō. Chaikin and the Tahara Municipal Museum state he was the son of Utagawa Yoshitora (fl. c. 1836-1882).1 Chaikin also writes that he called himself Mōsai after 1874 and was also known as Utagawa Shungyō.2 Most of his extant prints are senso-e of the Sino-Japanese War or kaika-e (prints of modernization and Westernization).
The online database of the Fine Arts Museums of San Francisco, provides the following information on "Shungyo Nagashima":
The British Museum lists the artist Nagashima Shungyo as being active 1850-1910.4
Several sources suggest or imply that Nagashima Shungyō, rather than being the son of Utagawa Yoshitora, is one and the same with Yoshitora. This seems to be based upon their reported family and given names Nagashima Tatsugorō 永嶌辰五郎 being the same5 and their both frequently using the art name Mōsai 孟斎 in signing many of their prints. I think they were two different artists, based upon stylistic and subject matter differences in their prints. In addition, they had different recorded home addresses for the year 1880. Andreas Marks tells us that Yoshitora's home address in 1877 to 1878 was Kandaku Sudachō Yon-banchi, in 1879 Kyōbashi Matsukawachō Roku-banchi, and in 1880 to 1881 Kanda Kajichō Roku-banchi. Shungyō's address on this collection's 1880 print The Glory of the Imperial Flowers is given as Kandaku Sudachō Yon-banchi, matching Yoshitora's 1877-1878 address but not matching his 1879-1881 addresses.6

5 Although I think the addresses given for artists were somewhat suspect as they sometimes were the address of the publisher.
