First generation Kawachi-no-kami Kunisuke was born Kameyama, Ise province. He studied in HORIKAWA Kunihiro school. He was hired regularly by SEKI Kazumasa. He lived in O-saka. He died on 30th May Sho-ho 4(1647).

First generation Kunisuke's children (e.g. Musashi-no-kami Kunitsugu, second generation Kawachi-no-kami Kunisuke ("Naka-Kawachi"), Higo-no-kami Kuniyasu, Ise-no-kami Kuniteru) were also good at swords making. The family and school were flourished.

[ Highlight ] Considering the situation, the enemy's attack when one rides on "kago" (palanquin), to be able to, and improve the ability of thrust from the inside of "kago", the length of blade is shortened and sharpened. So it is called "kago-yari" as well.

This is rare yari, which was created by first generation Kawachi-no-kami Kunisuke. It may be considered that to meet the requirement of O-saka samurai in early Edo period, the form of yari has high standard of practicability, based of experiences. The tension and consciousness of protection can be felt by its form. It has magnificent clear ji-bas.

On the book "Shin-tos kan-sho-roku (the appreciation records of Shin-tos)" (published in Tenmei 3(1783) by MINOURA Yoshitaka), he referred first generation Kawachi-no-kami Kunisuke and mentioned :
" All of the swordsmiths of this school, they are good at creating Yaris, such as"Sankaku-ho Ho-zo-in", "Chidori ju-monji" and "Sasa-ba-gata", etc. Their forms, distribution of materials are perfect. It was well known fact that at the experimental cutting test, they succeeded high points". It was understandable that he was known as a master of Yari making. Please appreciate the yari on your own hands.

[ Conditions ] There is a tiny scratch on "ha-chu" of yari blade, but it is not significant. The status of polishing is so good. The koshirae, which had ao-gai(blue shell) and shu-nuri(red painting), was created in modern times. It maintains perfect beautiful conditions.
