the imperial japanese navy's history of successes, sometimes against much more powerful foes as in the 1894–1895 sino-japanese war and the 1904–1905 russo-japanese war, ended with the navy's almost complete annihilation in 1945 against the united states navy, and official dissolution at the end of the conflict. japan's current navy falls under the umbrella of the japan self-defense forces (jsdf) as the japan maritime self-defense force (jmsdf). it is still one of the top navies in the world in terms of budget, although it is denied any offensive role by the nation's constitution and public opinion.
