following japan's surrender to the allied forces at the conclusion of world war ii, and japan's subsequent occupation, japan's entire imperial military was dissolved in the new 1947 constitution which states, "the japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as a means of settling international disputes." japan's current navy falls under the umbrella of the japan self-defense forces (jsdf) as the japan maritime self-defense force (jmsdf).
