hey! sorry to bother you, but I've been doing some hunting around, trying to figure out Yamanbagiri Kunihiro's origins, and I came across a few articles that all reference the same English translation of japanese sword legends. in it, it implies that Kunihiro's duplicate (soon to be name Yamanbagiri) was the one who actually slew the witch - is it true? where did the original get its name? do you have any idea? you seem to be one of the most knowledgeable abt tkrb sword histories around here
Hello, anon, and it’s no bother at all!
To put it simply: there are two different witch slaying legends, one for each Yamanbagiri. I’ll list the important info about it (otherwise it’d get too long with historical master changing…).
Under the cut to save your dash.
?? - Forged by Nagayoshi Chougi of Bizen Osafune, given to Hojo Ujimasa. There’s request issued to slay a mountain witch on Mt. Togakushi in Shinano country, which was where the sword earned its name.
Tensho 14 (1587) - The Chougi sword was owned by the Hojo clan, before it’s given to Nagao Akinaga.
Tensho 18 (February 1590) - Nagao Akinaga commissioned Horikawa Kunihiro to make Yamanbagiri Kunihiro.
Tensho 18 (May 1590) - Horikawa Kunihiro received the request to give Chougi’s Yamanbagiri an inscription.
After the Siege of Odawara (May - August 1590), Nagao Akinaga lost everything to Toyotomi Hideyoshi, including his life. Yamanbagiri Kunihiro ended up with the surviving vassal, Ishihara Jinzaemon, after that.
At this point, the sword picked up a witch slaying legend. In order to make a living, Ishihara and his pregnant wife were making their way to Shinshu. However, along the way, his wife went into labour.
He left his wife with an old woman living in the mountains and went back to get medicine. By the time he return, he found the old woman eating his newborn child. Realising what happened, Ishihara supposedly used Yamanbagiri Kunihiro to kill her. It’s said that when she died, her white hair disappeared like smoke.
