In the wazamono lists
The 『懐宝剣尺』 (Kaihō Kenjaku), of 1797, reissued in 1805 and 1815, places Wakasa no Kami Ujifusa among the fifty swordsmiths of the 良業物 (yoki-wazamono) grade, the third of the four, according to the English and Japanese Wikipedias and the Japanese Sword Index. Some source calls him 最良業物 (saiyoki-wazamono), as if he were of a higher grade; the published lists give 良業物 (yoki-wazamono), and that is the one we take.
The katana of kantei no. 821
A katana signed 若狭守氏房 (Wakasa no Kami Ujifusa) was the answer to NBTHK kantei no. 821: wide, with a long chū-kissaki, a midare of gunome and a jizō bōshi. The translation does not give its length, its date or its owner.
Designated works
The State’s cultural properties database has no work of his (search for 氏房 (Ujifusa) of 4 October 2026), and we have not found any in ColBase or the e-Museum either. We have not been able to check whether the Seki swordsmiths’ museum or other museums in Gifu and Nagoya hold any.
A blade by his son
The JSSUS reviews a hira-zukuri wakizashi by his son, Hida no Kami Ujifusa, of 40.2 cm and of the era 慶長 (Keichō, 1596), with a shortened nakago and its mounting, Tokubetsu Kichō of the NBTHK in 1967. It is not by the father, but it serves for comparison: a medium or large kissaki, coarse itame with masame or tight, whitish itame, a wide, square notare with pointed gunome and a cloudy nioiguchi. In Tomita Kiyama’s ranking of shintō swordsmiths (1933; published in 1935) the son, Hida no Kami Ujifusa, appears, and not the father, according to the Japanese Sword Index.
