Tameto is a late- swordsmith of Karakawa in , a locality on the border with , attached to the Fukuoka line. Two signed works of his carry the same year. A signed no Karakawa-ju Saemon no Jo Fujiwara Tameto is dated on the reverse the third month of Bunpo 1 (1317), and a signed no -ju Tameto is dated the sixth month of that year. The published sources note that the Meizukushi treats him 'as drawing on the line of Fukuoka Korekuni, but in fact' this is not clearly established. His name also carries a question of transcription. The dated reads Fujiwara, the paper gives Sugawara, and the , as cited for the , records a Bunpo 1 work signed Kuchikawa-ju Sugawara Tameto, admitting that where Kuchikawa lay is unclear.
His is a quiet hand within a school better known for flamboyant . Every blade on his record is built as a . On the two signed the published sources describe the in the same plain phrase, 'forged in , tightly packed, with rising'. The temper on the is 'a with small mixed in, entering', and the dated breaks the same line into . The dated , though shortened, keeps 'a somewhat broad and a healthy figure'. The , judged the same hand, is slender, with a slightly extended point and a pleasing .
The shows the same restraint at a smaller scale. It is a blade with and wide grooves on both faces. The is tired overall and somewhat rough, with a straight , and the temper is a slender shallowly undulating, with and , the a normal small round. Its entry says plainly that 'it does not make his lineage or anything else clear, but it is a rarity', and adds that 'it is a pity that it is tired'.
The other face of his record is the attributed to him. Here the is mixed with and stands overall, the faint. The slender undulates shallowly with , and , entering well and running, and the is straight to a small round. The published sources accept the attribution on the basis the signed work sets. 'Extant signed works are extremely few', and they are 'for the most part with an admixture of and '. In that sense, the paper concludes, 'the traditional attribution may be accepted'.
For the collector he is a rare and carefully documented late- name. Fujishiro grades him Jo , and the Toko Taikan places him in the upper middle of the field. No National Treasure or Important Cultural Property stands to his name. His official record is four works: the two signed designated before the war, the dated , and one . At certification the dated was owned by Nomura Hisatsuna of Kagawa and the by Ninomiya Kojun of Niigata. The , formerly of Tanzan Jinja, is recorded in Honma's inventory of the Imperial collection. These are long-held pieces of heritage rather than blades that pass through the market. A signed Tameto of recorded whereabouts is among the rarer things a student of work could encounter, and one comes to light, when it does, only with patience.
