	In 1863, Japan completed her first domestically-built steam warship, the "Chiyodagata", a 140-ton gunboat commissioned into the Tokugawa Navy (Japan's first steamship was the Unkoumaru -雲行丸- built by the fief of Satsuma in 1855). The ship was manufactured by the future industrial giant, Ishikawajima, thus initiating Japan's efforts to acquire and fully develop shipbuilding capabilities.
