Need help with a tang translation!

[Raggedymanny]

Hey guys, I've been a long time lurker around here, and I have seen how good you guys have been with tang translations in the past. My father came by this by way of his father when he came back from WWII. Neither of us has a clue of course, and that is why I am asking here. What the heck does this stuff mean?!

Here are the pics, I am using a high resolution pair of images to make identification easier.

I apologize for the mega image size, can anyone help me out with this?

Thanks!

Blade was made by a smith named Tadahiro. First two kanji are his family name (can't read) and are written in a form of Japanese called "sosho" script which is very difficult for even most Japanese to read! There is a small "Seki" kanji stamped into the blade at the top which identifies the blade as a WWII era non-traditionally made blade for military service. Lacquered marks on the reverse are assembly/stock numbers with no significance. Hope that helps.

Thank you, that is very helpful as I had no clue what it said. We've had it sitting in a closet for many years and I figured I would ask someone that knows a lot more about it than I do! I appreciate you helping me out with it.
