Gō Yoshihiro

Gō Yoshihiro (the same name with a different character for Gō) is a swordsmith of Etchū Province said to have been active from the late Kamakura period into the early Nanboku-chō period. He is said to have lived in Matsukura-gō, Niikawa District, Etchū Province (present-day Uozu City, Toyama Prefecture), and his go, "Gō," also derives from this place name. He is counted among the disciples of Sōshū Masamune and among the Ten Great Disciples of Masamune (Masamune Juttetsu), and is said to have died young at the age of twenty-seven. Combined with this tradition of an early death, almost no securely signed works survive. All surviving works are unsigned and are limited to those that later appraisers such as the Hon'ami family certified as Yoshihiro's. Regarding Norishige of Matsukura, who also achieved great renown in the same province, there are views that the two were fellow disciples under Masamune, and views that Norishige was Yoshihiro's teacher. The relationship between the two has given rise to various theories since ancient times.

His style is rooted in the Sōshū tradition. The jigane has tightly packed itame grain, with thick ji-nie and chikei, and yubashiri, kinsuji, and sunagashi appear. The hamon is based on notare undulations mixed with gunome, with plentiful ashi and yō. The nioi is deep, with konie, and it is bright and clear. Both the jihada and the hamon are bright and clear. The quality of the jigane is said to be the finest among Masamune's disciples, and he possesses the bearing of a top Sōshū craftsman, reflecting his teacher Masamune.

His representative works are either unsigned pieces authenticated by appraisal, or pieces bearing gold-inlaid attribution inscriptions (kinzōgan-mei) or red-lacquer attribution inscriptions (shu-mei) by the Hon'ami family. All are transmitted as meibutsu. The Tomita Gō (unsigned Yoshihiro), which was handed down in the Maeda family, is designated a National Treasure and is held by the Maeda Ikutokukai Foundation. The Inaba Gō of the Kashiwabara Museum of Art (Yamaguchi) is also designated a National Treasure. The Samidare Gō of the Tokugawa Art Museum is an Important Cultural Property. It is a single sword that was owned by Kuroda Nagamasa, Tokugawa Hidetada, Tokugawa Iemitsu, and Tokugawa Mitsutomo, second lord of the Owari Tokugawa, among others. The Matsui Gō, named after its possession by Matsui Sado-no-kami, is a Yoshihiro with a shu-mei bearing attribution by Hon'ami Kōjō. It is an Important Cultural Property and is held by the Sano Art Museum. The Kuwana Gō, known for having been owned by Honda Tadamasa, is an Important Cultural Property and is held by the Kyoto National Museum. Murakumo Gō and others have also been transmitted as meibutsu. Because securely signed works are virtually nonexistent, the saying "No one has ever seen a Gō or a ghost" even came into being.

Later evaluation of him is extremely high. Together with Sōshū Masamune and Awataguchi Yoshimitsu, he is listed among the Tenka Sansaku (the Three Great Smiths; also called Meibutsu Sansaku), and Gō works were also prized in the Kyōhō Meibutsuchō. Because his works are unsigned, their value rests on the Hon'ami family's attributions and attribution papers (origami). Their rank is considered saijōsaku, the highest grade. That he was placed among the Tenka Sansaku without any signed works to his name speaks well to the singularity of the reputation of the swordsmith Gō Yoshihiro.
