Special Feature : Yamamura Masanobu was originally a lord of the castle but when he saw the 2nd generation Nobukuni makes a sword he was so attracted by the smith’s high skill and decided to learn sword marking from the smith.

From Aoi Art : Yamamura Masanobu’s style is very similar to his teacher the 2nd generation Nobukuni.
At a glance, this sword looks like Shintogo’s works, especially in terms of the Hamon, it’s really nice. It makes sense that Dr. Kunzan wrote Kasaku(a fine piece of work), it’s quite rare that he used this word in his Sayagaki.
The Horimono(carving) are also awesome, they are very similar to those of the 2nd generation Nobukuni.
We strongly recommend this masterpiece, don’t miss it.
