After the Ōnin War broke the Ashikaga order, a century of Sengoku warfare armed nearly every province in Japan. The era rewards a discriminating eye: routine work exists in quantity, and beside it stand custom blades of the first rank.
This is a tantō attributed to Yamamura Yasunobu, an active swordsmith during the Ōei period (1394-1428) from the Yamamura school of Echigo province. It features a unique blackened dragon horimono with gold highlights and a crisply carved Sanskrit character invoking Fudō Myōō. The blade is accompanied by a fine set of koshirae with a harvest theme, signed by Toshitaka, and a kozuka signed by Ishiguro Masayoshi (gimei).
