Special feature: The Echigo Yamamura Nobukuni school began at the end of the Nanbokucho period. It is said to continue until the end of the Muromachi period.
It is said that Yamamura Masanobu was originally a student of Nobukuni the 2nd. But according to Dr.Kunzan’s theory, Yamamura Masanobu may be a student of the Nobukuni the first.
Please see the text on page 403 of the Kanto Hibisho Book.

From Aoi Art: He was a student Nobukuni the first and moved to Echigo Yakamura province. Yamamura Masanobu is a head of the Yamamura school. NBTHK paper said simpmy “Yamamura”.
So we cannot say that it is Yamamura Masanobu.
But it is similar to that. The blade is wide and Mitsumume Nanbokucho style Tanto. The Jigane has beautiful Hamon and Kinsuji. We strongly recommend this Tanto for you.
