He taught a large number of pupils, among the most important of whom were Ishibashi Kazunori, Satō Shien, and Yamamoto Shōun. In terms of style, Katei's work sits within the broad lineage of bird-and-flower painting associated with Tani Buncho and Tsubaki Chinzan. His output consisted of both monochrome ink paintings and richly coloured works in opaque pigments. He possessed a repertoire of auspicious imagery and themes derived from Chinese culture that were popular during his day. In his earlier decades he produced an equal number of landscape compositions to those depicting birds and flowers, as well as some portrait paintings, but in his final decade he concentrated on producing densely coloured paintings (saimitsuga) of birds and flowers on a large scale for both exhibitions and imperial commissions. Katei's student, Ishibashi Kazunori, took a large group of drawings from the studio with him to Britain in 1904, which he sold to the Liverpool businessman, Cedric Boult and his wife, Katharine, in 1913. The couple's son, Sir Adrian Boult, donated these in 1956 to National Museums Liverpool, and some were transferred to the Royal Ontario Museum and the National Museum of Scotland.
