Awa no Kami Fujiwara Ariyoshi is recognized in -period sword treatises -- including the Kaji Hayamidashi and the Ichiran -- as a disciple of Kunihiro, resident in Kyoto. His sole dated work, a inscribed Keicho 2 (1597), predates the permanent settlement of Kunihiro at in Keicho 4 and is, apart from Kunihiro himself, the earliest dated blade among the master's followers. The craftsmanship of that sword already displays the skill of an upper-ranked craftsman (joko), and its style shares affinities with Kunihiro's celebrated "Yamanbagiri" (Important Cultural Property). From these observations, the concludes that Ariyoshi did not so much learn the later, fully formed manner as study more directly the style of the higher-ranked masters that underlies it. He is thus regarded as a transitional disciple from the period when Kunihiro was shedding the manner of "Furuya forging" and moving toward " forging," and as among the most senior pupils within the group.

Extant works by Ariyoshi are exceedingly few; even counting , , , and together, they would likely not reach ten pieces. Yet the has consistently characterized each surviving example as "indispensable for research on this smith" and "extraordinarily precious as documentary material." His blades convey an archaic, time-worn flavor producing a subdued () taste, and collectively they illuminate the critical transitional moment in which the school took form. As source material for understanding both the individual artisan and the broader genesis of the tradition, Ariyoshi's works are regarded as precious and highly dependable.
