The second-generation Dewanokami Yukihiro was the natural son of the first-generation Dewanokami Yukihiro of the Soba- line at Saga. He styled himself Tobanojo, first signed Yukinaga, and received the title Dewanokami in Jokyo 1 (1684), two years after his father's death. The Kokon Kajibiko gives his death as Genroku 14 (1701), but the published sources call this an error, since works dated Genroku 16 (1703) and Hoei 3 (1706) survive. They regard as credible a genealogy submitted by Matahachi, ninth-generation head of the Yukihiro house, which records his death on the eighteenth day of the ninth month of Kyoho 11 (1726). One earlier paper still follows the Genroku 14 date.
His record is small. The published sources state that "the second generation's works are extremely few in comparison with the first, and his manner follows the first generation", and four of his blades stand in the tier. Three of them carry the of the line: mixed with , at times with angular forms, and , or with large and clusters of joined by straight passages. enter, the is deep and adheres well, thickly on one blade with some coarser . and run through the edge, and the is bright. Two of the three open with a straight at the base, and one shows -like and near the . Of one the sources write that over "a refined komenuka-like it masterfully shows the long- distinctive to , and its form too is bold".
The fourth blade is a over a tightly forged with dust-fine and fine , deep in , with fine and . The sources describe it as "a manner of comparatively uncommon for this smith" and single out its evenly adhering and its bright, clear . On his blades the runs to a , usually with a long turnback.
The line between father and son is not always settled. On a signed no Tobanojo Yukihiro with the Aranda- inscription, the sources note that the placement of the signature toward the and the form of the character hiro recall the first generation, while the form of and the Tobanojo prefix make the second generation the stronger view. They conclude that "a definitive attribution between the generations should await further documentation", and still call it a work that "brings its distinctive together without any break". Another, somewhat short is signed on the rather than the usual , which the sources take as the sign of a special order.
Four works are on record, none in a higher tier, and their current owners are not recorded. With so few signed works by the second generation, an example of his hand is seldom encountered, and the published commentary itself shows how closely such a blade must be read against his father's.
