At least one generation held the official title Saemon no Jō, as attested by signed works bearing the full inscription Bishū Saemon no Jō Hidemitsu. Extant dated works span roughly from through Shitoku and into Meitoku, providing valuable reference material for the chronology of late production.

Works in sound condition are praised as — well-preserved blades in which the forging is well-refined and delicate. The dated inscriptions that survive on numerous pieces are repeatedly characterized as excellent reference material and valuable source material for understanding late production. The open-based found in certain works is noted as already suggesting an anticipation of the stylistic approach of Ōei-period , positioning Hidemitsu at a transitional moment within the tradition. While the acknowledges that the workmanship of the group is generally considered not to reach the level of the Kanemitsu faction and similar lines, Hidemitsu's finest examples are singled out as outstanding among this smith's works — blades whose earnest, straightforward craftsmanship and luminous secure his standing as the leading figure of the tradition.
