The Niō school (二王) worked in Suō Province along the San'yōdō, the western reach of the country where heavy concentrations of temple estates, including lands of Tōdai-ji, drew the province into exchange with the Yamato heartland. The members describe the line as beginning in tradition around the Hōen era (1135 to 1141) with a Kiyozane or Kiyohira, but they agree that no securely attributable work by either survives, so Kiyotsuna is regarded in effect as the school's founder.

A blade of top-grade workmanship and condition, formally judged to rank with a nationally recognized Important Art Object (Jūyō Bijutsuhin). Awarded only at the NBTHK’s competitive annual examination.
Of Japan’s roughly 2.5 million registered swords, only 12,307 (about 1 in 203) have ever attained Jūyō.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
