The heads of Japan’s parliament are in the final stages of compiling a report on measures to prevent further decline in the number of imperial family members. A central proposal under consideration is the reinstatement of former male royals along the male line through adoption.

The imperial family has decreased from 21 members in 1989 to 16 today. Of the current members, three males remain in the line of succession and five are unmarried women, including Princess Aiko. If all princesses leave the family upon marriage, membership would fall to 11.

The adoption proposal is more controversial within parliament than an alternative measure that would allow female members to remain in the imperial family after marriage. The report is expected to be completed soon. Tsuneyasu Takeda, a member of one of the 11 former princely houses abolished after World War II, has been referenced in coverage of the discussion.
