Special feature : Governer of Okayama prison Shigesaburo Emura impose tough guidance on prisoners for making Japanese swords.
According to the books, Shigesaburo Emura named also Nagamitsu but I think the quality and Yasurime and also Hamon are different.
Emura balde is rather slender and good work hamon.
Nagamitsu was named just only Nagamitsu and Ichihara Ichiryushi Nagamitsu, Ichihara nagamitsu, Bizen Nagamitsu and Bizen Kuni Oite Karasu Jyoka Ichihara Ichiryusi Nagamitsu(quite rare) and so on.
Generally these kind of Syowa-to are not good reputation but I think these blade were polished very poor compare with Yasukuni shrine blade which were polished well known polisher.
If the blade will be polished by good polisher, the blade will be changed a lot.
Sometimes these blades are much better than Yasukuni shrine blades.
It is true that the sword quality is very difference between good and poor swords. Because the sword makers were composed by prisoners and technical standard are quite different. Anyway I polished Emura blade before and changed a lot like shinshinto blade. Please looks at the hamon and jigane around your place. High quality of blades will be good investment in the future.
This Nagamitsu is interesting hamon like shinshinto blade.
