了戒
Description
A Master of the Rai School—Ryokai
Ryokai (了戒) was a swordsmith active from the mid- to late Kamakura period in Yamashiro Province (modern-day Kyoto Prefecture) and belonged to the Rai school (Rai-ha), a prestigious Kyoto lineage. He is transmitted to have been either the son of Rai Kuniyuki, the de facto founder of the Rai school, or the son or younger brother of Rai Kunitoshi, and he played an important role in advancing the Rai school. He is known for the distinctive practice of inscribing his dharma name (monastic name) 'Ryokai' as his signature, and his lineage later continued into the Nobukuni school.
Style of the Yamashiro Tradition and Rai School
Ryokai's workmanship exemplifies the characteristics of the Yamashiro tradition and Rai school at a high level. The jigane exhibits well-packed koitame with fine jinie, displaying the refined and dignified grain characteristic of Kyoto work. The hamon is based on suguha (straight edge), interspersed with small midare and ko-gunome, with a bright and keen nioi. His calm and refined work conveys well the sophisticated aesthetic consciousness of the Rai school.
Signature and Transmission
Ryokai's works characteristically bear his dharma name 'Ryokai' as the inscription, and examples are known with long inscriptions including location, secular name, and date, such as 'Yamashiro Province resident Kurogoro-suke Ryokai, Kagetsu 3, third month.' Works bearing dates such as Shōō, Eien, and Kagetsu are transmitted, and some examples are designated as Important Cultural Properties. The use of a dharma name as a signature is rare among swordsmiths and serves as a crucial means of identifying Ryokai's work.
Distinction from the Taima School
Ryokai is sometimes mistakenly spoken of as a swordsmith of the Yamato tradition's Taima school, but this is incorrect. Ryokai was definitively a swordsmith of the Rai school of Yamashiro Province, and his workstyle displays the Rai school's characteristic tightly-packed koitame grain, distinct from the masame-dominant grain of the Yamato tradition. The Taima school was one of the five Yamato schools and a separate lineage based in Nara, distinct from Ryokai's line.
From the Late Kamakura to the Nanboku-chō Period
The late to final Kamakura period when Ryokai flourished marked the height of the Rai school's prominence as Kyoto's representative swordsmith group. Under the reputation of the Rai school established by Rai Kuniyuki and Rai Kunitoshi, Ryokai likewise produced reliable work, primarily in tachi. His works were transmitted to temples and shrines and are thought to have been valued as dedicatory blades. Subsequently, Ryokai's lineage connected to the Nobukuni school of the Nanboku-chō period, serving to transmit Kyoto's sword-forging tradition to later generations.
Touken-za and Ryokai
Touken-za presents Ryokai as a master swordsmith of the refined style produced by the Rai school of Kyoto. Possessing the rare individuality of inscribing his dharma name as his signature, Ryokai's swords—continuing the Rai school's tradition after Rai Kuniyuki and Rai Kunitoshi—are precious legacies that convey the refinement of the Kamakura-period Yamashiro tradition to the present day.
