*We're coming up on the four year anniversary of this thread (had to repost on new forum) so I've revamped it with new Der Eisendrache information, please read until end as much of the beginning is slightly incorrect now*
Shi No Numa and Takeo: The Entwined History
In World War II, there was a biological weapons research and human experimentation team known as Unit 731, and they had many compounds. One of the compounds was in the very southern parts of Pingfang, Manchuria, where their excuse for the facility's existence was that it was a lumber mill, so they had logs and wood everywhere. Rumor from around the compound is that they referred to their human specimens as "logs." In the Rebirth intel for the campaign, it states that there was "Japanese biological research in Manchuria on the part of the Imperial Army's covert R&D group Unit 731."
The Imperial Army was taking part in it, you say? Seems appropriate, seeing as Takeo Masaki is a Captain in the Imperial Army, judging by the stars on his uniform. Also note that Shi No Numa has wood all throughout the complex, not to mention The Flogger, made from wood. Some of you might say that there was no human experimentation going on inside Shi No Numa and that Takeo Masaki likely had no involvement in it, if it was there. However, I will kill two birds with one stone here and quote something from Takeo's biography, given by Treyarch:
That sounds pretty disturbing to me, doesn't seem like a stretch for him to be involved in human experimentation. As noted in the Rebirth intel, it states there was Japanese research in Manchuria. However, some will point out that in Kino der Toten and on the Call of Duty website, quotes reference Shi No Numa as being in Japan, as opposed to where Manchuria was, which was China:
"I found another rock. Maybe they stole this from Japan..." - vox_plr_2_egg_pedastool_1
"... we've pinned what sounds like an SOS signal to a remote jungle location in Japan."
On the original thread, though, I feel as though AlphaSnake put it very clearly:
Then, in a Origins Letter from the Field, Takeo mentions that he fought in the "battle of Muken" and his "leadership & victory" had been brought to the Emperor's attention. Now, there's no such "battle of Muken" in World War I, so what it appears he's talking about is the "Battle of Mukden" that took place between the Japanese and Russians in 1905, which the Japanese coincidentally did get a victory. If you're curious what Mukden is, it was the capital of Manchuria, which puts Takeo in Manchuria.
Two counterarguments that I can't reconcile are the sound files of the Kookaburra and Hyena, both of which aren't found in Manchuria, but can be found in New Guinea, as Matuzz points out in his thread (I can't locate the CoDz version).
DER EISENDRACHE EDIT
New information has recently come to light with Der Eisendrache. In a radio, we heard one Dr. Groph discussing a Division #9's more ambitious weapons designs (prior to discovering Element 115), so it was immediately assumed by me and many others that Division #9 meant Germany's own 9th SS Panzer Division. I mean after all, the SS has heavy Group 935 ties and the division is a Panzer division. Then, we got a cipher (partially) saying that "After the success at the Rising Sun Facility, Division #9 is moving with Phase #2" and that the "island facility" was also operational. Immediately, the frame switched from not a German 9th Division, but a Japanese one.
If that wasn't enough, it was found shortly thereafter that scraps of paper were littered through Der Eisendrache, each with Japanese writing on it. The translation is rough (reason in link above), but Takeo is writing to the Emperor and the very end mentions that he is now on the island. Additionally, he makes clear that Division #9 is present. @Matuzz, being the skilled theorist that he is, then went and found the Imperial Army's 9th Division (and wow). Their 9th Division went to both the Battle of Mukden in 1905 and were permanently re-located to Manchuria in 1940.
I may have been off about the initial Unit 731 information four years ago, but I seemed to be on the right track with Manchuria! Anyway, I hope you all enjoyed,
