The Iron Bridge and Osaka Castle, from the series Famous New Places in Osaka (Hanfu shinmeisho)

This 1870 color woodblock print by Hasegawa Sadanobu II, from the series Famous New Places in Osaka (Hanfu shinmeisho), depicts an iron bridge over an Osaka canal with the castle keep rising in the distance, and belongs to the body of kaika-e (civilization-and-enlightenment pictures) that Sadanobu II produced during his residence in the Kansai treaty ports in the late 1860s and early 1870s. Iron bridges were among the most visible monuments of the early Meiji Westernization program: the Tokugawa-era city had been served by wooden bridges, and the new Meiji administration deployed iron and steel bridges as visible emblems of technological modernization and engineering competence in conscious imitation of European urban infrastructure. The series title Famous New Places in Osaka explicitly inverts the older Edo-period meisho-zue convention, which had cataloged celebrated historical and natural sites, to focus instead on the newly built structures of post-Restoration Osaka — the iron bridges, foreign settlement buildings, railway stations, and Western-style hotels that defined the city's emerging modern identity. The Fine Arts Museums of San Francisco (Legion of Honor) holds the print with accession number 1963.30.5692, part of the Achenbach Foundation for Graphic Arts collection that is one of the most substantial American repositories of nineteenth-century Japanese printmaking. The composition's purple borders are typical of late-1860s Osaka print production.
