Queen Himiko/Pimiko set the tone for the Tomb period, however this period can be separated into two separate eras, the Kofun 250 - 538, and the Asuka 538 - 710.

​

The Kofun era is named for its burial mounds.  Shintoism emerges at this time as the prominent belief system.

​

The Asuka era is distinguishable by the arrival of Buddhism 552 CE, as well as the Taika reforms in 645 CE.

​

These two eras are often referred to as the Yamamoto period.
