Iwakura Tomomi
On 3 January 1868, when Iwakura Tomomi arranged the seizure of the Kyoto Imperial Palace and initiated the Meiji Restoration, which resulted in the creation of the post-Shōgun Empire of Japan, Nakayama was among the courtiers who supported this action. According to Peter Kornicki, "Nakayama's cooperation with Iwakura had been essential to the success of the coup d'etat". Nakayama and Iwakura both became influential courtier-politicians in the Meiji period.
