The Asuka period was a time of simplified burials.
Compared to previous eras, tombs became smaller in scale and their contents simpler.
Simplified burials meant the simplification of funerary acts as a whole. Asuka period tombs thus had smaller mounds compared to those of previous times. Stone chambers also became smaller, compact and lightweight wooden coffins replaced the heavy stone ones used until then, and burial goods changed while declining in quantity.
