Osaka jōdai (大坂城代?) were officials of the Tokugawa shogunate in Edo period Japan. Appointments to this prominent office were exclusively fudai daimyō. Conventional interpretations have construed these Japanese titles as "commissioner" or "overseer" or "governor."
This bakufu title identifies an official responsible for holding and defending Osaka Castle (大坂城・大阪城 Ōsaka-jō?), and for administration of the city of Osaka. This office was considered only slightly less important than the Kyoto shoshidai; and this important daimyō officer was charged with guarding the security of the Kansai region. Originally, there were six jodai, but that number was eventually reduced to only one. Conventionally, the man appointed to this essential position would have previously demonstrated his abilities and loyalty by serving as jisha-bugyō or by having succeeded in another similarly important role. From this high position, a career path would have typically included promotion to the office of Kyoto shoshidai and then to a position amongst the rōjū in Edo.
During this period, Osaka ranked with other urban centers, some of which were designated as a "shogunal city." The number of such cities rose from three to eleven under Tokugawa administration.
