Off with her head!

As for the succession, until this baby was born there was serious talk of changing the 'rules' so a female could inherit the throne, like in many European royal families. I recall the Prime Minister was all for modernising but he was up against a solid brick wall of resistance to the idea from the ultra conservative, traditional, rigid royal household ('the men in grey'), although not necessarily from the Emperor himself so nothing happened. Then little Prince Hisahito was born and the crisis averted, although he's the ONLY male heir at the moment so someone had better provided a spare heir just in case.
