Artisan Shodai Nobukuni (信国)
Era Nanbokuchō period
Explanation From old times, the first-generation Nobukuni has been said to have been a disciple of Sōshū Sadamune, and his era has traditionally been transmitted as the Kenmu period. However, among extant works there are no dated examples from Kenmu or its immediate vicinity, nor are there any works that can be inferred to go back so far; moreover, because the style of the earliest surviving Nobukuni blades—those bearing dates from the Bunwa and Jōji eras—connects directly with Sadamune, the prevailing view today is that the Enbun–Jōji period should be regarded as the time of the shodai. According to transmitted records, he is written as the son, or alternatively the grandson, of Ryōkai (son of Ryōhisa). Further, features such as the presence of suguha—a tradition of the Rai school—in works dated Enbun 3 and Kōan 1, and the tendency of the forging to show flowing areas regardless of whether the temper is straight or irregular, suggest the plausibility of such traditions.
This wakizashi has the Nanbokuchō-period form characterized by slightly sun-nobi proportions, a wide width, and shallow curvature. In the jihada, the itame partially becomes flowing, thick ji-nie adheres, and chikei enters well; the hamon is notare mixed with small gunome, with finely appearing ashi. These features of both ji and ha demonstrate the characteristics of shodai Nobukuni, and thus the attribution is readily affirmed. The notare and the rounded boshi are tempered with refinement, and the nioiguchi is bright. Although simple, the bo-hi and soe-hi carved kaki-nagashi on both sides further display the highlights of this smith’s work, making this an example that fully presents his merits.
