Miwa Jusetsu (1910-2012) was born in Hagi, in Yamaguchi Prefecture, at the southwest end of Japan's main island. Miwa, the heir to a long family tradition of Hagi pottery, was known for his stark, rough style, which was inspired by the movements of the sea. He inherited the title of Kyūsetsu XI, and was named a Japanese National Living Treasure in 1983. Miwa's older brother, Kyūwa (Kyūsetsu X) received the same designation in 1970. Hagi-yaki has its origins in the forced relocation of Korean potters that occurred during Japan's 16th century invasions of Korea. The potters were sent to various regions, and those who settled in Hagi created the Hagi-yaki style.

Miwa Kyūwa (1896-1981), born into the legendary Miwa family of Hagi-yaki potters, both continued and revived the Hagi tradition. He inherited the family title of Kyūsetsu X, and is renowned for his work in improving the traditional light-colored Hagi glaze, developing the famed snow-white variant. The glaze is characteristic of Miwa's work and this yunomi is an excellent example. Miwa was named a Japanese National Living Treasure in 1970. His younger brother, Jusetsu (Kyūsetsu X), would later receive the same honor.

Fujiwara Kei (1899-1983) was born in Bizen, Okayama Prefecture, the location of one of Japan's Six Ancient Kilns (六古窯). Fujiwara didn't start making pottery until he was 40 years old. In his youth, his consuming interest was literature. But once he turned his attention to pottery, he quickly became a master potter and received the title of Japanese National Living Treasure in 1970. His son, Fujiwara Yū, was destined to receive the same honor.
