It reflects the wide-bodied style characteristic of the Yamashiro school.
Swords from this era often feature carvings on the blade.
The Nobukuni line continued from the first to the fourth generation.
This piece is likely the work of the late first generation or the early second generation Nobukuni (Saeemon no Jo).
