The decoration was confined to simple scroll patterns or conventional designs in impure blue sous couverte. The factory of Mikawachi was not then under official patronage. It was a private enterprise, as is proved by the fact that Higuchi Joen (Joen's father had changed his family name of Imamura to Higuchi) and Ishimaru Yaichiemon, a grandson of the well-known Risampei, together with other potters of the district, petitioned their feudal chief to sanction the digging of the Ajiro-tsuchi.

This was the discovery of a very fine porcelain stone at Fukae, in the island of Amakusa. The discovery is attributed by some to Yajibei, a descendant of Higuchi Toen; by others to Yokoishi Tōshichibei, also a man of Korean origin. The former tradition would seem to be correct, inasmuch as Yajibei was afterwards worshipped at Mikawachi under the deified title of "Joen Daimyōjin." The Amakusa stone was not used alone.
