If you have any more pictures of the mounts we'd love to see them, sometimes you can find the officers surname on the guard under the fittings with these.

That is a very fine Daisho, can't recall seeing one with with matching cutting tests before.

Very nice indeed, it appears to be an Utsushi of Yokoyama Daijo Sukesada.

Thanks for sharing, is one of them in military mounts?

The extra material around the Sarute looks to be based off a particular style of mounts often found on Koa Isshin Mantetsu swords: https://www.artswords.com/Mint_Imperial_Japanese_Generals_Gunto_Mounted_Katana_020308.htm

If you can confirm it was brought back from WWII then it may have been made in a Japanese occupied territory.

Nice looking sword, it's an early Type 94 pattern of good quality (note separate Sarute and Mon on Fuchi). The Mon is a variation of Daki Myoga (embracing ginger leaves) rather than Paulownia, unfortunately you won't have much luck narrowing down officers based on the Mon. You may find the officers surname on the fittings or under the Fuchi if you're lucky. The blade appears to be a 1930's Showato, I once had a very similar sword likely from the same shop. As the battle of Iwo Jima is relatively well documented you may be able to find detailed Japanese unit documents or staff photos from the 109th Division: https://en.wikipedia.org/wiki/109th_Division_(Imperial_Japanese_Army)

Many of us would appreciate some photos of the tables and show if possible.

For comparison:

Agree with Ray, the sword is in a perfectly reasonable state. Was there any writing on the Shirasaya?

The mounts themselves appear to be original and of good quality, as you would expect with the Suya stamp. Suya Shoten was known to have supplied Koshirae for a number of Imperial clients, and Gassan Sadakazu was a Teishitsu Gigei-in. The blade itself is somewhat uninspiring for a Gassan work, but that could be the photos.

At a glance many of the swords look too good to be true, when you examine the pictures closely you'll quickly see why they're so cheap. That being said if your goal is to simply own one genuine Japanese sword that's papered I doubt you'll find a more affordable source.

From the Sugata it would more likely to have been a polearm, such as a Naginata or Nagamaki.

Hi Mike, well you've just about exhausted all the wrong ways to put it together so looks like some assistance is in order. Two piece Habaki fit like so and sit above the Tsuba:
