He was a swordsmith of the Echizen Shimosaka school that produced Yasutsugu 1st and Nagasone Kotetsu. ・Both Shichirobei 1st and Jinsuke 2nd received the title of "Yamashiro Daijo". Jinsuke Kunitsugu 2nd engraved the chrysanthemum crest on the Nakago. ・Kunitsugu 3rd assumed the name "Yamada Shichirobei" like the first generation and received the title of "Yamashiro Daijo" in the first year of the Kanbun era. He later became Yamashironokami and moved to Edo, where he forged swords in the service of the Matsudaira family, the feudal lords of the Echizen domain. He left works from Kanbun 2 to Enpo 2 (1662-1674), and some of his swords are engraved with the chrysanthemum crest on the nakago. 【Blade/condition】 ・The blade is in very good + condition. ・Hamon is clearly expressed and suitable for viewing. ・The finish is good, showing not only the beauty of its appearance but also its sharpness. ・The signature is clearly engraved on the Nakago, and there is also a certificate paper from NBTHK, so you can enjoy it with peace of mind. 【Koshirae】 ・TSUKA's sharkskin is beautiful and the design of the Tsuba and Menuki are beautiful. ・The Saya is also painted black to match the black color of the Tsuka, creating a unified and beautiful Koshirae. 【Attention before bid】 ・This is a truly domestic Japanese sword that has never left Japan. When exporting, an export permit must be obtained. It takes about 20 business days from the time the buyer makes payment to the time the transportation process begins. This is because exporting Japanese swords requires permission from the Agency for Cultural Affairs. ・Export of Japanese swords from Japan to other countries is restricted. Depending on the situation of the shipping company and your country of residence, it may not be possible to ship. We will of course do our best to send the item, but if no carrier is available, we have no choice but to cancel the transaction. (So far we have been able to transport them without any problems in most cases.) ・Regardless of the carrier's situation, China and Russia are banned from importing Japanese swords.
