Emperor Ninmyō
22 March 833 (Tenchō 10, 28th day of the 2nd month): In the 10th year of Emperor Junna's reign, the emperor abdicated. The succession (senso) was received by his adopted son.  Masara-shinnō was the natural son of Emperor Saga, and therefore would have been Junna's nephew.  Soon afterwards, Emperor Ninmyo is said to have acceded to the throne (sokui).  This was confirmed in ceremonies.
