Yoshino Court Swords

Establishment of the Yoshino Court and Tōken

In 1336 (Kenmu 3), Ashikaga Takauji established the Muromachi shogunate and enthroned Emperor Kōmyō (Northern Court). Emperor Go-Daigo fled into the mountains of Mount Yoshino and founded the Southern Court. The Nanbokuchō turmoil that began in this way also produced a special era in the history of nihontō. In the Yoshino Court (Southern Court), the ōdachi and nodachi were prized as emblems of loyal retainers, and the swords worn by Southern Court generals went beyond mere weapons to become political and spiritual symbols.

In this era, Emperor Go-Daigo continued to assert the legitimacy of the Southern Court against the Northern Court. Southern Court generals often faced large armies with small, elite forces, so large weapons that allowed a single warrior to hold off several enemies were practically advantageous. The rapid development of ōdachi and nodachi with a blade length exceeding 3 shaku (about 90 cm) was because the realities of the Nanbokuchō battlefields created direct demand.

Kusunoki Masashige and the Sword Culture of the Southern Court

Kusunoki Masashige, the emblematic figure of Southern Court loyalty, devoted his life to loyalty to Emperor Go-Daigo, from the sieges at Chihaya Castle and Akasaka Castle to the Battle of Minatogawa. The legend that Masashige fought wielding an ōdachi spread widely in later ages, and the equation of Southern Court loyalty with the ōdachi became established. After Masashige's death (1336, Battle of Minatogawa), his spiritual influence continued to raise the morale of Southern Court supporters and became the cultural foundation of the veneration of the ōdachi in the Yoshino Court.

Kitabatake Akiie, as a close attendant of Emperor Go-Daigo, fought campaigns from Ōshū (the Tōhoku region) to Kyoto and led troops. Because Akiie himself was an accomplished warrior-scholar, he is highly regarded as a figure embodying both the cultural refinement and martial vigor of the Yoshino Court. This shows that the sword culture of this era was not limited to the manufacture of practical goods but carried cultural and spiritual meaning.

Bizen's Response

In the early Nanbokuchō period, the activities of Bizen swordsmiths deserve attention. Osafune Kanemitsu was the Bizen swordsmith most active during the Nanbokuchō turmoil. In the style of "Sōden-Bizen," which incorporated the techniques of the Sōshū (Sagami) tradition, he left a wide range of works from ōdachi to tantō. Kanemitsu's ōdachi display the bold form of Nanbokuchō-style proportions (taihai), tempered with the lively gunome-midare of Sōden-Bizen. They are still highly valued today as practical and artistic masterpieces that met the demand of Southern Court generals.

Osafune Tomomitsu and other Bizen swordsmiths, said to be younger brothers of Kanemitsu, were also active during the Nanbokuchō turmoil. While meeting large volumes of orders, they maintained a certain level of quality. Bizen swordsmiths are said to have supplied both the Southern Court and the Northern Court, and their position is thought to have been artisanal rather than political.

Contribution of the Yamato Tradition

Many Yamato swordsmiths were tied to temples in Nanto (Nara), such as the Senjuin school, which belonged to Tōdai-ji. Tachi and ōdachi made during the Yoshino Court period by smiths of the Tegai and Senjuin schools form a distinctive group of works. These fuse the refined Yamato-den style of masame-hada and suguha with the bold proportions of the Nanbokuchō period.

The Taima school, said to have been associated with Taima-dera, also continued into the Nanbokuchō period. It traced its origin to Kuniyuki of the mid-Kamakura period.

Traditions after the Fall of the Southern Court

The Southern Court fell in 1392 (Meitoku 3), when Emperor Go-Kameyama merged into the Northern Court. However, the influence left by the Southern Court's sword culture lasted a long time. Because the lineages of prominent Southern Court generals continued to hold the spiritual authority of "loyal retainers of the Southern Court" through the medieval and early modern periods, the tachi of the Yoshino Court period that they owned were prized as meibutsu, with the added value of "transmitted from the Southern Court." The value system for swords that carry such "historical narratives" is directly connected to the tradition of emphasizing provenance (raireki) in the later collecting culture of nihontō. When appreciating tachi of the Yoshino Court period, being aware that the intense historical context of the Nanbokuchō turmoil is condensed into a single sword, along with the beauty of the blade itself, leads to a deeper understanding.
