Today we move from the Iron Throne of Westeros (Game of Thrones) to the Chrysanthemum Throne of Japan. Emperor Akihito abdicated his throne in favour of his son Naruhito. Fascinatingly, because Japanese monarchs are not allowed to abdicate, the Japanese parliament had to pass a law allowing Akihito to do just that. It was also a one-time deal. The next emperor would need similar legislation should he ever want to abdicate. You will also note there are a lot of male pronouns in this paragraph. By law, women cannot inherit the throne. And when royal princesses marry, they leave the royal household.
Not surprisingly, the news today had some graphics depicting the family tree of the Japanese royal family. And you all know how much I am a sucker for genealogy related work. This piece comes from the BBC and it is pretty simple. It uses a nice grey bar to indicate the generations and some titling indicates who succeeds whom.
The graphic also makes rather painfully clear that if Japan wants to preserve its monarchy, it will need to embrace some kind of reforms. There are only four males left in the line of succession and only one is likely to have any sons.
