The Ito school (伊藤派) was a prolific kinkō lineage based in Kanda, Edo, in Musashi province. The line was established by Masanaga (正長, d.
1727), who received appointment as official tsuba maker (kōgi o-kakae tsubashi) to the Tokugawa Shogunate following an audience with Shogun Ienobu in 1710. Successive heads bore the character 正 (Masa-) in their art names, producing ten recorded generations from the Genroku era through the Meiji period. Learn more →
