His name was Soubei.He was working for Matudaira Daimyo family as a sword making Samurai.He moved to Kuwana province with his master and then he moved to Edo at Tenpo 2 nd year.At that time he was high reputation of cut well swords maker. some times we found his swords which was done Saidanmei and also possession name on the tang of the blade. Generally speaking, the quality of Munetsugu is one of the top swordsmith in late Edo period and without any faults among his swords.

From Aoi Art: The peace of Koyama Munetsugu with clear Gunome-midare, beautiful Jigane and peculiar Hamon. Koshirae is red Toppei, it is difficult to find this kind of Koshirae these days. This sword is typical Koyama Munetsugu wonderful Gunome and choji midare hamon without kizu and flaw. Bright and clear Hamon. I watched many Munetsugu but I never see a failed sword. therefor many swords collectors judged high reputation.
Probably, He had a strong determination not to release bad works to the market. His subjects are similar with Chounsai Tsunatoshi but some different points. The Munetsugu’s shape of the bo-shi is midarekomi style and very clear Jigane compare with Tsunatoshi.
Also, he seems to have been on good terms with cutting tester human body Yamada Asauemon and said to have been instructed on sharpness from him.
It is well known that many of the works by Munetsugu asked to Tameshigiri by Yamada Asauemon.
It is also described in the sword dictionary, When Kiyomaro opened sword factory in Yotsuya Iga-cho, he was in Samon-cho at the time. There is a story that Munetsugu got angry and wrote a letter to a duel because of Kiyomaro start without greeting to
Koyama Munetsugu
In Edo period, generally, If someone started working, the person must go around to greeting in order to smooth communication.
But Kiyomaro didn’t do that. So he got angry and had a duel. Remembering the sword maker’s temperament.
I’m interested. This Munetsugu is really bright and clear hamon and Koshirae is Toppei style which is now rather difficult to see.
I recommend this fantastic sword with Koshirae.
