Artillery in Japan is recorded in the 13th century. It was not used widely before the Sengoku period in the 16th century.[1]
History
In the 1840s, the Tokugawa Shogunate began to anticipate that either British or French military might attack Japan. Takashima Shuhan (1798-1866) submitted a petition to the shogun calling for the purchase of Western firearms. In 1841, a demonstration of Western gunnery made a strong impression.[2] Powerful conservative factions in the shogunate resisted change.[3]
