Some additional info that I have read over the years not in the report below. After the Philippines campaign, most Japanese oil supplies were completely cut-off. (Largely cut-off by our subs already anyway) The remaining IJN Fleet that survived were basically "grounded" to being moored in ports due to lack of fuel. Remaining fuel was assigned to ASW escorts and submarines. Except for the sortie by YAMATO and her escorts in April 1945.
After NAGATO was camouflage as described at the pier she was tied up to, she was still located and bombed by allied aircraft. At some point her undamaged AA guns were removed for shore installations. If I remember right, the plan was to use NAGATO as a floating battery with her 16-in guns during an allied invasion. I have never seen it stated as to when exactly she was moved from the pier she was tied up to, out into the bay and anchored as seen in these photos.
: I was never clear why they did this to Nagato?
: What did it accomplish or what did they hope
: to accomplish by disarming her and
: mutilating her?

: In my quest of going through the 80-G
: collection at NARA, I have been keeping my
: eye out for "good" images of the
: former IJN NAGATO after the USN acquired
: her. All I have been finding have generally
: been poor images taken in September 1945 or
: afterwards, normally in overcast weather.
: However the last two trips to NARA I have
: come across photos taken by at least two
: different photographers from some of the
: first USN ships to arrive in Tokyo Bay. One
: area of NAGATO at the end of the war that
: has always puzzled me, was the midships area
: aft of the stack and in front of the stack.
: The Japanese had cutdown the stack and the
: mainmast tripod prior to the end of the war,
: but it was unclear what was going on around
: where the stack HAD been. I finally have a
: couple of good photos of that area.
: It looks like a "SHACK" was added
: aft of the stack!!! It is pretty clear from
: the series of photos that moist of her
: secondary armament had been removed as was
: already known. But these photos give a
: pretty good idea of where the guns had been
: and what the bulwarks around those guns
: looked like.
