Hisamichi (1626-1711, floruit 1650-1673) was the pupil of Iga Kami Kinmichi. In 1661 he was granted the title of Omi Daijo; the following year he was awarded the title of Omi no Kami and the right to use the kiku mon. He became 0ne of the Kyoto Go Kaji or five great swordsmiths of Kyoto. Although he was not originally a member of the Mishina family, the honour of being selected as one of the Kyoto Go Kaji meant that he established an influential family with in the Mishina school.

Hisamichi followed his teacher's styles. He used gunome midare hamon with box-like patterns, as well as suguha, and toranba with tobi-yaki.

The first generation did not have a son, and it appears that he adopted Kinshiro, the son of the third generation Rai Kinmichi. Hisamichi made quite a few swords with his son. However, the second generation used an edagiku (chrysanthemum and branch) above his mei.

This was originally a huge sword with a blade of well over 30 inches. The date of the suriage is uncertain but to judge from the patination a second suriage was made relatively recently, probably so that it could be fitted to Army mounts during WW2.
