Special feature : Ko-mihara is the name of a swordsith group lived in Mihara of Bingo province prospered around the last Kamakura to the last Muromachi period.
Masaie and Masahiro are the representative swordsmiths of this school.
Distinctive points of their swords are shirake-utsuri and slight masame pattern on the jitetsu,
hotsure and uchinoke on the hamon and round boshi though the comprehensive style resembles to the Yamato School’s and neighboring Aoe School’s.
The reason why Yamato School influenced to this School is that there were many shoen manor in medieval Japan especially owned by Buddhist temples or Shinto-shrines in Yamato province.
This katana shows a robust feature: relatively wide Mihaba and thick kasane as a Koto and its longish kissaki.
It makes a well-balanced proportion.

The blade looks Aoe school but NBTHK judged as Komihara.
Komihara and Aoe is very similar becase of neighbor country.
So sword makers had comunicated each other.
