His style
- For the Japanese Wikipedia his typical manner is an itame with midare-utsuri and a chōji midare hamon that, in his best pieces, has 重花丁子 (jūka-chōji), double chōji like double-flowered cherry trees: the showiest blade of the school.
- The Tokyo National Museum gives him as the Fukuoka Ichimonji swordsmith with the showiest chōji, and his manner, with a wide, robust blade, a showy chōji and utsuri, as the most mature form of the Bizen sword.
- The NBTHK uses Yoshifusa’s hamon as a point of comparison for that of Bizen Saburō Kunimune, whose chōji have a narrow base and are not jūka-chōji.
