Here we have three prehistoric Japanese pots from three different eras.
The first one is from the Jomon period (8000 B.C.E. - 250B.C.E.) which was the earliest period in the Japanese history. The word jômon means "straw-rope pattern,"which was used to describe the style of the pottery from that period. The pots were mostly used to storing food but were also used for storing corpses such as that of an infant.
The second one is from the Yayoi period (250 B.C.E. - 250 C.E.). As you can see it’s, much less decorated than the pot from the Jomon period. But what it lacks for beauty it makes up for practicality for it’s much easier to use. These pots were used for storing, cooking and for offerings.
The last one is from the kofun period (250 C.E. - 600 C.E.). This kind of Kofun pottery is named sue, it was brought from korea. The Sue style was almost identical to the original styles of Korean pottery, but while Korean pottery was more decorated, Sue pottery followed the traditions of native Japanese pottery, being more simple. In the Kofun period pots weren’t used to store corpses any more.
