Hidemitsu is recorded in the as beginning with a first generation active in the Kenmu era, followed by smiths of the name across four generations spanning the , Shitoku, and Oei eras, with further generations continuing into the period. However, strict generational differentiation remains a matter that must await further research. He belonged to the lineage and circle of Kanemitsu, and is counted among the group of smiths known as the - — a designation used chiefly for those -period smiths within the Kanemitsu tradition who produced blades with comparatively shallow curvature.
Hidemitsu's forging shows tightly worked with extremely fine yet thickly adhering , fine , and distinctly standing . His is principally composed of small mixed with , , angular elements, and -ba, with and entering throughout. The is typically -dominant with , producing a bright and clear workmanship. The irregular intermixture of diverse temper forms, together with the overall small-scale patterning of the , clearly demonstrates the characteristic features of the style. His signatures are characteristically small and executed with fine chisel strokes, a manner that accords with the general practice seen among works.
Across the extant body of work, both and are consistently praised as — sound and well-preserved. The forging is described as particularly excellent and of fine quality, and the bright, clear appearance of the is singled out as especially desirable. That several blades retain tangs with date inscriptions from the period makes them extremely valuable as reference material for the study of this tradition. His rare form, with its markedly extended and distinctive , further attests to the breadth of workmanship within the lineage.
