All members of Pegu's male line to the throne having been exhausted, Shin Sawbu ascended the throne as queen in early 1454.
Two of her brothers, Binnya Dhammayaza and Banya Ran I, and one of her sons, Binnya Waru, had already ruled as kings of Pegu.

In 1457, shortly after ascending the throne, the Buddhist world celebrated the two thousandth anniversary of the Buddha's Paranirvana which in Southeast Asia is dated to the year 543 BCE.

After ruling Pegu for around seven years, in 1460 she decided to abdicate and move from Pegu to Dagon where she could lead a life of religious devotion next to the Shwedagon pagoda.

Shin Sawbu chose a monk to succeed her on the throne of Pegu.
The monk Pitakahara, who had helped her escape from Ava, left the sangha, was given the titles Punnaraja and Dhammazedi, and became her son-in-law and a suitable heir to the throne by marrying her younger daughter Mipakathin.
