Raku ware was born out of an unprecedented methodology and technique.
However it was not called Raku ware when Rikyû and Chôjirô were active.
It was initially called Ima-yaki, “now wares”, wares produced at the present time, that is to say, tea bowls that looked avant-garde. They were subsequently renamed juraku-yaki, “juraku wares”, due to the fact that the Raku home was nearby the Jurakudai Palace and also Sen Rikyû who lived inside the premises of the Palace was a central figure to the birth and the promotion of Chôjirô's tea bowls. Jurakudai was a palace built by Toyotomo Hideyoshi (1537~1598), the leading warrior statesman of the time, and was one of the greatest symbols of his age.
Juraku-yaki was eventually abbreviated as Raku-yaki, Raku ware. It is believed that Hideyoshi presented Chôjirô with a seal bearing the Chinese character for Raku.
Raku then became the name of the family that produced these wares.
This is the only example in the history of a family name becoming synonymous with the ceramics they produced. Now Raku ware has become a general term for a type of ceramic technique globally known and practiced. However, at first it meant just wares pioneered by Chôjirô together with Rikyû and practiced exclusively by the Raku family.
