Tamekiyo (為清) is a swordsmith of the Fukuoka school in Province, active during the early period. Reference works place his career around the Kenpō (1213–1219) or Tenpuku (1233–1234) eras, though no dated works survive and all known signatures consist of only two characters, leaving a firm chronology unresolved. While smiths bearing this name appear in , Karakawa, and lineages in the , every extant authenticated work is appraised as belonging to the group.
Tamekiyo's exhibit the robust characteristic of early work: broad , pronounced -zori with retained at the base, and a compact . The forging is a tightly worked with adherent and fine , over which vivid rises prominently, at times approaching the appearance of . The characteristically divides into two registers — a flamboyant mixed with in the lower half, transitioning to a quieter -based in the upper half — rendered predominantly in with slight . The intermittent appearance of , a distinctive tempering effect at the blade's base, is identified in the designation literature as a reliable hallmark of this smith's individual style.
Tamekiyo's surviving oeuvre demonstrates an outstanding level of workmanship among smiths of the period. Designation scholars have noted that while individual blades vary in the degree of flamboyance, the consistency of signature style across extant examples points to a single accomplished hand. One notable blade bears a provenance tracing to the Mizuno house of Domain, having been bestowed by the shogunal household — testimony to the esteem in which these works were held. Collectively, Tamekiyo's blades make manifest the high technical achievement of the Fukuoka tradition at its formative stage.
