As Lord Keeper of the Privy Seal of Japan from 1940, Kido became one of the most influential advisors to Emperor Hirohito following the death of Saionji Kinmochi. He recommended to Hirohito that Konoe succeed Mitsumasa Yonai for a second term as Prime Minister of Japan and was active with Konoe in the movement to replace the existing political parties with the "Taisei Yokusankai" (Imperial Rule Assistance Association) to form a single party state.
