Imperial Household Council

Fifty-one members lost their Imperial status in 1947 with an approval of the Council.

The Council has discussed and approved of six marriages since its establishment.

No princess of the blood needs a marriage approval unless she marries a member of the Imperial House, because she will automatically become a commoner upon marriage and her husband will never be a member of the Imperial House under the rule of patrilineal succession. Seven princesses have married without the Council's approval since it was established.

In the summer of 2016, the aged Emperor Akihito indicated his desire to retire, leading to special legislation permitting the first abdication in over two centuries. The council met in December 2017 to formalize how and when the event would take place.

Kōzoku Giin (皇族議員), literally Imperial Representative, refers to the Imperial Family members elected as members of the Imperial Household Council by mutual election among the adult members of the Imperial Family excluding the Emperor. They vote to elect two reserve members from the Imperial Family in the same way.[1]

Princess Yori ceased to be a reserve member of the Council because she got married and became a commoner on 10 October 1952. Princess Takamatsu became a reserve member in replacement for her.

On 3 September 2003, Prince Mikasa was reelected to his fifteenth consecutive term of office since the Council's establishment. Crown Prince Naruhito was voted out. It was for the first time since 1963 that the crown prince was not elected as a member or reserve member of the Council.[2]

On 5 September 2007, Empress Michiko, six princes and nine princesses voted to elect Prince and Princess Hitachi as members of the Council, and Princess Mikasa and Prince Akishino as reserve members. Prince Mikasa was reported to have excused himself for his old age in advance. Crown Prince Naruhito was not elected again while his brother, Prince Akishino was voted in for the first time. The next election was in September 2011.[3]

On 7 September 2011, the regular election was held by the 18 adult members of the imperial family. This time the elections were not held at the Imperial Palace, but in an Agency conference room to reduce energy consumption.[4] Both the members and reserve members were re-elected.[5]
