Awesome...thanks! Questions:

1) Do you have anything for Chief Engineers for RO-106? The list skips them.

2) Is the following correct for one of RO-112's Torpedo Officers?
ODERA Shunsaburo 大寺俊三郎
Naval Academy 69 (209/342)
MID - 25 March 1941

I-54 Torpedo Officer - 05 August 1944 - 28 October 1944
LCDR - 20 November 1944 (posthumous promotion) (KIA 28 October 1944)

3) Do you have anything for Navigators for RO-112? The list looks like they were accidentally skipped.

4) If LT OMAGARI Kosuke was KIA as Navigator of I-13, but how did he survive the sinking of RO-115? According to her TROM, she was lost with all hands. Could OMAGARI have been relieved prior to 1 February 1945 by an unknown officer? Here's what I currently have for him:

I can understand your point. But it is certain that 島田万里 was Torpedo Officer, so I think that 大寺俊三郎 was also so.

I missed getting this part of the info in the library.

The only possible reason is "OMAGARI wasn't on the RO-115".
Movement of RO-115
December 28: arrival at Penang
January 19: departed Penang
January 21: arrival at Singapore
January 23: departed Singapore
January 31: sunk
Whether OMAGARI, who had been attached to the 19th Submarine Division, was able to get on in Penang depends on where he was working before. For example, I've heard that the officers, especially junior officers who must move had to arrange their own means of the move to the south from Japan. Regular flights of flying boats may have been available during the stable period of the prewar period, but it was probably difficult to find a means of the move during this period of defeat. Therefore, I think that there were many cases that "He was able to escape the KIA because he couldn’t get on his new ship like OMAGARI." On the contrary, there were cases that "He could not get off and share his fate with the ship".

Awesome...thanks!

On the contrary, there were cases that "He could not get off and share his fate with the ship".

Another case of this could very well be that of LT (Sup.) TAKAHASHI Yasuaki (Pay. Aux. 3), who was Paymaster of CHOKAI from 1 May 1943 - 20 August 1944. On the latter date, he was relieved by LT (Sup.) BABA Yasutaka (Pay. 30), but was still aboard CHOKAI when she was sunk on 25 October 1944. Both were KIA and posthumously promoted LCDR (Sup.).

She was not put into the actual battle in Japan because of her advanced German craftsmanship and inferior Japanese ability, and she served as a target for ASW training.
She was submerged in Wakasa Bay after the War. A project to identify her was recently launched by crowdfunding. It was obtained with Multi-beam Sonar Exploration. In the second photo, we can see that the rudder of her bow is identified.

So you also don't have hard evidence for May 10 appointment.
Originally, OIKAWA Jun’ichi was appointed Torpedo Officer on April 30, but this appointment was invalidated because he became a KIA. I suspect that ISOBE Hideo was appointed on April 30 for "site treatment " for this.
LT / LT ISOBE Hideo 磯辺秀雄 (68): 30 April 1944 - 25 June 1944
It is only my guess.
