A succession dispute in Japan breaks out in 672 following the death of Emperor Tenji.

The name refers to the jinshin or ninth year of the sixty-year Jikkan Jinishi calendrical cycle, corresponding to the Western year 673.

Tenji had originally designated his brother, Prince Oama as his successor, but later changes his mind in favor of his son Prince Otomo, who takes the throne as Emperor,

Otama reigns for less than a year during the course of the violence that erupts as a result of factional rivalries before taking his own life.

His uncle Oama succeeds to the throne as the Emperor Temmu.
