The sayagaki states, Naotsuna no Ko to Den Nidai Nambokucho Goki (the son and school of Naotsuna late Nambokucho).
There were three generations of Sadatsuna, the first was the son of Naotsuna, working in Sekishu (Shimane prefecture) which produced very high quality tamahagane. used in swords from ancient times.
Naotsuna is considered one of the Masamune jutetsu, and along with Go Yoshihiro ansd Kaneuji, is argued to be the best student of Masamune. However, Masamune ( 1264 -1343), while Naotsuna was active in the later part of Shohei (1348 - 1370), a signed example dated 1375, precludes the fact that he could have studied under Masamune. Nonetheless, his swords are solidly in the Soshu tradition. $23,000
