Details	Chōgi was a swordsmith of the Nanbokuchō period, counted among the many Bizen smiths known as the Sōden-Bizen group, and he is regarded, alongside Kanemitsu, as one of the foremost masters of the school. The dated examples of his works range from the Jōwa era (1345–1350) to the Kōryaku era (1379–1381). His style shows two distinct tendencies: one leaning toward a nioi-dominant temper, and the other displaying a strong nie presence in both ji and ha. In the latter case, the influence of the Sōshū tradition is emphasized even more strongly than in Kanemitsu’s works, leading to the long-standing description: “Among Bizen swords, the smith most removed from the Bizen style is Chōgi.” His hamon is often strikingly individual, with bold undulations and varied activities. The forging typically shows itame hada, with abundant ji-nie and fine chikei running throughout. This particular blade has a wide mihaba and an impressively large ō-kissaki, giving the overall form a sense of power. The hamon displays a variety of activities, the forging is skillfully executed, and the workmanship is of a highly distinguished quality. The sword is accompanied by a koshirae mounted with a vermilion ishime-ji lacquered scabbard (shu ishime-ji nuri saya uchigatana koshirae). Kumagai Yoshiyuki, the metalworker associated with this koshirae, was active in the mid-Edo period. He was born in Sendai, Mutsu Province, and upon moving to Edo first resided in Shiba Gensukechō. While remaining in Edo, he served as a retainer artisan to the Hosokawa clan of Higo Domain and later established himself in Yotsuya. He became known as “Edo-Higo” or “Yotsuya-Higo” for his distinctive style of fittings.
