Some help needed with Shin-Gunto mei and Kokuin on Tang - Yoshida Kaneaki?

[tbonesullivan]

As best I can tell, the tang is signed 関  吉 田 兼 明 - SEKI  YOSHIDA KANEAKI. I found an oshigata with similar style, though it has another character JU. I can't find anything on the kokuin though. Is it for a school and not a smith?

 

Any help would be greatly appreciated.

Ah, 惜っしい! The last Kanji is 門/Kado/door, so this is 関吉田兼門 Seki Yoshida Kanekado.
