The Tokyo National Museum record
“He was a smith of Fukuoka, in Bizen, in the early Kamakura period, and with Norimune he was chosen as one of Go-Toba’s rotating smiths. The blade is shortened, but it has a slender and elegant sugata, and the hamon is a calm suguha with ko-midare. It is one of his few signed works.”
What belongs to the school
According to the Japanese Wikipedia, the school forges tachi with funbari, high koshizori and ikubi-kissaki, a dense itame with fine ji-nie and midare-utsuri, and chōji tempers. These are traits of the school in general, not measured on his blades.
