History.

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. Powerful factions in the shogunate resisted change.
During the 1864 Bombardment of Shimonoseki, European naval guns were shown to be superior to Japanese cannon on shore.
