Celadon porcelain originated in China and was introduced to Japan by the 10th century. Among the aristocratic classes at that time, celadon wares from China were regarded as the finest imported goods. They adored its mysterious blue and named it "secret-color."
Production of celadon ware began in the Hizen region, the northwestern part of present Kyushu in the early Edo period (1603 CE - 1868 CE), and the technique was later passed on to Kyoto and nearby areas. In 1957, the craft technology was designated a national intangible cultural asset. Celadon is still being loved and worked on by many potters and artists today.
