Three years later, on November 10, 1915, the Sokui no rei (The enthronement of the Emperor) ceremony was held at the Kyoto Imperial Palace; but the Empress Teimei did not attend this ceremony due to her pregnancy with the forth child (later became Mikasanomiya).
3年後の大正4年（1915年）11月10日に京都御所にて即位の礼が行なわれたが、貞明皇后は第四子（のちの三笠宮）を懐妊中のため欠席した。
