Special feature: Yamamura Yasunobu was a student of Nobukuni(Kyoto, the first generation). They made swords for Samurai from generation to generation. At a glance, the blade is similar to Rai school. Suiken’s Sayagaki said that the blade is Rai Kunimitsu. Suiken is the author of a famous book called Encyclopedia of Japanese Swords. It is diffucult to say whether Rai Kunimitsu is correct or Yamamura Yasunobu is correct, but I feel that Nobukuni school is different.

From Aoi Art: According to the Sayagaki, Suiken said that the blade is Rai Kunimitsu. But NBTHK judged the blade as Yamakura Yasunobu. Suiken published the Encyclopedia of Japanese Swords, and we use that book. I feel that it is a little unreasonable for Yamamura Yasunobu. The Jigane is very good and Hamon is also elegant. In general, the Yamamura school has many Suguha Hamon. Yamamura Yasunobu was the lord of a castle and also made swords. His master was Nobukuni. Therefore, he calls himself Nobukuni.
