Very faded writing on a shirasaya for a mumei wakizashi

[rb87]

I found two Japanese blades in my late grandfather's house. He was an army doctor stationed in Japan in 1946. My dad remembers being told that a Japanese doctor who he worked with gave him a very old family sword. My dad never understood why, and didn't know anything about it. My best guess is that the Japanese doctor gave him the sword to save it from being confiscated and destroyed. It is a 50cm long wakizashi, and is mumei. However, there is some very faded writing on some paper glued to the shirasaya.  The other blade is a more ordinary gunto which does have a signed nakago and seems much newer, so this is the one that I am really interested in. 

 

I know that it is a longshot that anyone will be able to read this given the condition, but if anyone is up for a challenge, I would really appreciate if you could point out anything that is legible. 

Here is a photo of the saya for context:

There are two pieces of paper, both with some writing on them.

I have several more angles and photos in a google album if anyone is interested:

I would be very appreciative (and impressed) if anyone could tell me something about this sword based on these tattered labels.

That is a name and an old address in Tochigi prefecture.

 

都賀郡生井村白鳥 + some numbers (out of the image) – Tsuga-gun, Namai-mura, Shiratori, …

落合靖(晴?)郎 – Ochiai Yasuo(Haruo?)

 

I think that the first part of the address should be 下都賀郡 (Shimotsuga-gun), but I cannot see 下 in the image.

Wow, thank you so much for the help! I imagined that perhaps the writing would tell the story of the sword itself, but this makes more sense really. It's very interesting to have some information on where it came from. I'll have to figure out more about the sword the traditional way.

Hey Ray, I noticed you're a resident of Indiana like myself! I've sent you a message if you want to meet up with another collector.
