because he wanted to avoid every member's disposal. Instead of Sanjō, Iwakura became the substitute of the prime minister and prevented the dispatch of Saigō. Due to this decision, some people had complaints, and Iwakura was attacked by nine people led by Takechi Kumakichi in Kuichigaizaka, Akasaka. He was slightly injured but severely damaged mentally. (Kuichigai Incident) In 1873, Kido and Ōkubo raised written opinions about a constitution. Both opinions said that Japan should make a constitution as soon as possible, so to establishing a constitution became an urgent issue in Japan. In this situation, Ōkubo was assassinated in 1878, and Iwakura had to choose Itō Hirobumi or Ōkuma Shigenobu as a successor of Ōkubo. Itō wanted absolute monarchy in Germany, and Ōkuma suggested a parliamentary cabinet system in the United Kingdom. Ultimately, Iwakura chose Itō and Germany system as the constitution of Japan.

This station aimed to translate Japanese history into English. Death Although in poor health by early 1883, Iwakura went to Kyoto in May to direct efforts to restore and preserve the imperial palace and the buildings of the old city, many of which had been falling into disrepair since the transfer of the capital to Tokyo. Soon however, he became seriously ill and was confined to his bed. The Meiji Emperor sent his personal physician, Erwin Bälz, to examine Iwakura; Baelz diagnosed advanced throat cancer. The emperor personally visited his cousin and old friend on July 19, and was moved to tears at his condition. Iwakura died the following day, and was given a state funeral, the first ever given by the imperial government. Just before dying, Iwakura invited Inoue Kaoru over. Bälz and
