The Spin

Japan's male-only succession rule is pushing the Chrysanthemum Throne toward extinction — only three male heirs remain, and the oldest is 90. Blocking Princess Aiko, who has massive public support, in favor of adopting distant relatives nobody knows makes zero sense. The so-called "ancient tradition" of male-only succession only worked historically because emperors had concubines; that era is long gone.
