District Court of Tokyo, Ryuichi Shimoda et al. v. The State (1963)
“ The doctrine of sovereign immunity is applied not only to the State but also to the highest executive organs of the State, including the President, and it is held that these organs do not incur liability as individuals for their unlawful acts committed in the performance of their duties. It is true that, as the plaintiffs contend, the English doctrine that 'the King can do no wrong' has not been adopted as such by the United States, and how the doctrine of sovereign immunity, quite similar to the English doctrine, has come to be applied in the United State, is not well known. ”
