The Hirado Sa school, active in Hizen province during the Nanbokucho period, was known for its refined jihada and vibrant hamon, influenced by the Soshu tradition.

In Chikuzen Province, on the northern coast of Kyushu, the Sa school (左, the Samonji line) took shape in the early Nanbokucho period as a deliberate break with the Kyushu work that came before it. Its founder, the smith who cut the single character 左 on his tang, is read in the published sources as Saemon Saburo, commonly called O-Sa or Samonji; he is placed as the grandson of Sairen and son of Jitsua, the old Chikuzen line whose steel, in the words the NBTHK restates blade after blade, ran sunken and rustic in a restrained suguha inherited from Yamato.
