Special Feature : Minamoto Kiyomaro was born at second son of the Yamaura Masatomo village head Bunka 10th march 6th(1814) and studied at swordsmith Kawamura Toshinori with his old brother Saneo.
After that they moved to Edo and visited Kubota Sugane who was Military science person and sword battling expert. Kubota Sugane understood his making sword teqnique and made a smithy in his private garden. His skill grew up and called 3 major sword makers in Edo Suishinshi Masahide, Taikei Naotame and Kiyomaro. By the effort of the Kubota Kiyone Bukiko was settled in order to collect Money. and promised to make 100 swords for the customers but he made just only one sword and run away to Cyosyu province.
After 2 years later he returned to Edo and apologized to his master.
He made a beautiful sword for his master Kubota sugane which sword became Jyuyo Bijyutu right now. For Kubota sugane kun Yamaura Tamaki Kiyomaro sei :Kouka Hinieuma Nen hachigatu hi. the blade is long 2syaku 6sun 78,8cm 31 inches long. He was called Yotsuya Masamune.
He killed by himsely Kaei 7th(1845)
From Aoi Art : Nobody can emulate the tremendous Jigane and active hamon by Kiyomaro, especialy Jigane which consist of the itame hada with a lot of chikei like this sword, and active hamon. also the inside temper line is quite different from other sword makers.
It is quite unique that under the Kawamura Toshinori he studied Nioideki cyoji midare like Hujimi Saigyo and kikka hamon but after he moved to Edo, he made sosyu den style sword, it’s a big different subject compare with before studying sword technique.
In the end he killed by himself, in my opinion probably he realized that he couldnt make this kind of sword anymore…
Even though there is a deep rust in the ha, but not serious one.
I guess the reason why the blade was cut shortened is that Et Edo and Meiji era, Koto blade is very expensive compare Gendai blade like Koyomaro, Sa yukihide ,Munetsugu Naotane and so on.
So some bad man made Koto blade by using Gendai sword.
I think this Kiyomaro was changed to Sa, Masamune, Ooshizu and so on. It is very regrettable that the sword was changed to Koto blade. The blade is remarkable item.
