His workmanship was straightforward, similar to that of his father Ryouiri, but his glazes were not without a tendency to be pale. The yellow color of the clay is sometimes exposed.

Following Ryouiri, he was commissioned by the Marquis of Kishu to work on the garden pottery of his Nishihama Palace, and in May 1826, he received the seal of Raku from Chiho. There are five types of seals used. The one called “Kiraku seal” is said to have been written by Onuma Hyuga-mamoru, a Confucian vassal of the imperial court, and is said to have been written by him. The next two types of seals, large and small, in clerical script given by Chiho are so-called “seiryokuin” (seal of receipt). The small seal was used from the time of the Jokei 200th memorial service. The fourth, a small seal given by Sukeisai, is said to have been used on the 250th anniversary of Chojiro’s death. The fifth seal is said to have been made in his later years by the pen of Daitokuji Temple’s Gyokurin-in monk, Tadaso.
