Though arguably opposed to the shogunate, Satsuma was perhaps one of the strictest domains in enforcing particular policies. Christian missionaries were seen as a serious threat to the power of the "daimyō", and the peace and order of the domain; the shogunal ban on Christianity was enforced more strictly and brutally in Satsuma, perhaps, than anywhere else in the archipelago. The ban on smuggling, perhaps unsurprisingly, was not so strictly enforced, as the domain gained significantly from trade performed along its shores, some ways away from Nagasaki, where the shogunate monopolized commerce. In the 1830s, Satsuma used its illegal Okinawa trade to rebuild its finances under Zusho Hirosato.
