Unrecorded smith?

[DGARBUTT]

This is the date and signature from a katana that I have been given to sell. I have posted the mounts on another thread. I read the signature as Kashu Haruyoshi saku with a date of Eisho 12. I cannot find any reference to this smith. The only Haruyoshi I find using these kanji worked in the late 1600's and I have no reference to his province or a sample of his mei. If anyone has a reference to this smith please let me know. I believe that the smith is either unrecorded or either the date or the mei are fraudulent. Your comments are welcome. I will be listing the sword in the for sale section when I have priced it.

Hi,

 

Mei reads Ashu Yasuyoshi saku 阿州泰吉作 I think it is one of the Kaifu school.
