Iemori is a smith whose dated run in an almost unbroken file from Eiwa and Koo through Meitoku into the single-digit Oei years, and the published record opens its account of him plainly: he is a swordsmith of the Oei-era group, of whom 「作品は少ない」, surviving works are few. He belongs to the loose body of late- hands the literature calls , a category fixed by exclusion rather than by descent, the smiths who fall outside the specific lineages of Kanemitsu, Motoshige and Nagashige and are gathered under the one name. Iemori is counted within it alongside Hidemitsu, Mitsuhiro and Nariie, and the reads him in succession: a first generation placed in the group around the late Gentoku era, whose work is scarcely ever seen, and the smith of the Koryaku-to-Oei dates counted the third of some four generations under the name. Earlier entries make him a pupil of Yoshikage, and the published sources resolve the disagreement by reading each surviving blade for its style and its year-date rather than assigning it firmly to a generation.
His hand is a small-patterned , and the recurring judgment that fixes him is one of scale. The published sources describe his manner as Kanemitsu-style, a carrying in the cutting edge, and add at once that 「作位は兼光に及ばない」, the level of execution does not reach that of Kanemitsu, while the features of this group stand out clearly. Where the Kanemitsu line tempers a bolder , Iemori reduces the idea to a small that runs connected and threaded, mixed with angular and pointed elements and at the waist with an open koshi-hiraki , the whole running small and subdued, what the reference texts call a - tendency with . and enter, the temper is -dominant with , and faint and play through it. The answers the temper, a that points at the tip with , or on the quieter blades a straight passing into a .
The is the steel reduced to the modest register. He forges mixed with and a flowing tendency, the grain standing so that the older descriptions call it , and over it lie , fine sunk dark within the steel, at times a -like passage, and the that places his work squarely in the tradition even where the temper runs quiet. On his best blades the iron tightens and the reflection rises clearly. The is archaic for its date: a deep with marked and a small point, the shape the published sources read as the period character of the late into early , and the signature is cut in the manner shared across the group, a small six-character or a longer signature set with a fine chisel toward the .
Read across his dated span the work shows a single hand turning slowly toward the next age. The Oei grow heavy in the and add , and the published sources read this thick-, , small-pointed shape as the incipient features of the Oei- style; one Oei 2 is described as forging with , fine and dark -like lines, a prominent and a koshi-hiraki of small overall pattern that demonstrates the character outright. Yet the temper holds to the older vein, the connected retaining, as one is read, the lingering traces of the preceding era. A few pieces break the restraint: one wide Oei is noted for a unusually florid for so early a date, signed with thick, distinctive chisel strokes, which the literature prizes as study material for the smith. The 's four-generation succession and the absence of any securely first-generation work leave the strict generation-by-generation reading, in the words of the published sources, to await further research.
What sets Iemori apart within his group is told best by his own grounded traits rather than by comparison. His bright and his subdued, small-patterned with pointed and angular elements mark him as even as they keep him below the Kanemitsu mainstream, and his open koshi-hiraki and heavy late point him forward to Oei-, so that he stands on the threshold between the file and the next age of the school. The published sources name his kinship plainly, the austere 「師光・家助などにみる淋しい刃文」 seen in smiths such as Moromitsu and Iesuke, and they call his best work typical of the whole circle: in his finest dated the , and are read as typical for this smith and for his group, a piece they are willing to name 「家守の代表作の一口」, a representative example among Iemori's works. On one folded-signature they go further, noting that in comparison with works of the type 「鉄の鍛えがよく、匂口も明るく冴え」, the forging of the steel is particularly good and the bright and clear, an excellent level of workmanship.
Iemori is rated Chu-jo , and his standing is that of a documentary hand more than a market name. His designated works on record number thirteen and in the rank, with no National Treasure or Important Cultural Property among them, so the , signed and dated blades sound in and that recur in his record are valued as reference material for the group and for the working of at the turn into Oei-. Provenance is thin but real: one blade carries an Imperial line, others descend through the Hojo viscount house and from the collector Shida Sadashige, and recorded current whereabouts include the Hayashibara Museum of Art and the Tokyo and Kyoto National Museums. For the private collector this is a smith encountered chiefly through his dated , which appear from time to time and with patience rather than readily, prized less for flamboyance than for the legibility of a clearly dated, well-forged blade standing at the edge of the Oei- age.
