The shogunate also allowed and then ordered various domains to purchase warships and to develop naval fleets, Satsuma, especially, had petitioned the shogunate to build modern naval vessels. A naval center had been set up by the Satsuma domain in Kagoshima, students were sent abroad for training and a number of ships were acquired. The domains of Chōshū, Hizen, Tosa and Kaga joined Satsuma in acquiring ships. These naval elements proved insufficient during the Royal Navy's Bombardment of Kagoshima in 1863 and the Allied bombardments of Shimonoseki in 1863–64.
