京都御所
With Ōkubo Toshimichi and Saigō Takamori, on January 3, 1868, he engineered the seizure of the Kyoto Imperial Palace by forces loyal to Satsuma and Chōshū, thus initiating the Meiji Restoration. He commissioned Imperial banners with the sun and moon on a red field, which helped ensure that the encounters of the Meiji Restoration were generally bloodless affairs.
