Hello ijnfleetadmiral,

Could you post the Kanji for the following officers?
MATSUBARA Kanzo (TENRYU)
IWASHITA Akira (TAMA)

MATSUBARA Kanzo (TENRYU): 松原寛三 (39)
IWASHITA Akira (TAMA): 岩下鎤 (41)

1) I have conflicting dates for one of TENRYU's Navigators:
TAKAGI Banjiro
TSURUMI Navigator - 14 March 1922 - 15 October 1923
TENRYU Navigator - 1 December 1922 - 15 May 1923

TAKAGI Banjiro
TSURUMI Navigation Officer: 14 March 1922 - 20 November 1922
TENRYU Navigation Officer: 1 December 1922 - 15 May 1923
TSURUMI Navigation Officers
LT / LT TAKAGI Banjiro: 14 March 1922 - 20 November 1922
LT / LT KURAMOCHI Magoichi: 20 November 1922 - 15 October 1923
LT / LT MURAYAMA Seiroku: 15 October 1923 - 1 December 1924

2) I have conflicting dates for one of KISO's Navigators:
YAMANAKA Hideo
IZUMO Navigator - 15 October 1935 - 15 May 1936
KISO Navigator - 14 March 1936 - 1 December 1936

YAMANAKA Hideo
IZUMO Navigation Officer: 15 October 1935 - 14 March 1936
KISO Navigation Officer: 14 March 1936 - 1 December 1936
IZUMO Navigation Officers
LT / LT YAMANAKA Hideo: 15 October 1935 - 14 March 1936
LT / LCDR TSUKAMOTO Tomoichiro: 14 March 1936 - 1 December 1936

3) Is this correct for one of KISO's Navigators?
YOSHIZU Shinichi
KOTAKA Commanding Officer - 1 June 1940 - 15 November 1940
KISO Navigator - 15 November 1940 - 3 June 1941

I don’t have the data of KOTAKA. LCDR YOSHIZU Shin’ichi was detached from 1st China Expeditionary Fleet HQ on 15 November 1940. Is it sure that a LCDR was the CO of 50tons boat?

Awesome...thanks!

1) In reference to AGANO Navigator LCDR SHINBORI Masao (61) surviving her sinking, here's what I found in the TROM for destroyer OITE, which rescued AGANO's survivors:

16 February 1944:
160 miles N of Truk. At 1644, LtCdr William P. Gruner, on his first war patrol as skipper of USS SKATE (SS-305), fires four Mark-14 torpedoes at AGANO. Two hit her starboard side and set her afire. Between 2000 and 2330, OITE rescues 523 survivors including Captain Matsuda.

18 February 1944:
While entering Truk, OITE is hit amidships by a torpedo from one of Task Force 58's TBF Avengers. She breaks in two and sinks instantly with all but about 20 survivors. Captain Matsuda and 522 survivors of AGANO go down with her. Matsuda is promoted Rear Admiral, posthumously.

LCDR SHINBORI must have been AGANO's sole survivor.

Some more for you:

Awesome...thanks!

1) For NACHI, MATSUMOTO Masaru (54) was not Navigator when NACHI was sunk. I have the following for him:
NACHI Navigator - 15 May 1942 - 5 May 1944
YAMASHIRO Navigator - 15 May 1944 - 25 October 1944 (KIA)

2) Could this be correct for MYOKO Navigators?

KITAMURA Fumio
KAKO Navigator - 15 January 1934 - 15 November 1934
ATAGO Navigator - 1 November 1934 - 21 October 1935

4) For MOGAMI Navigators, I have LCDR YAMAUCHI Masaki (51) as Navigator for the early portion of the war. I believe he was MOGAMI's Navigator at Midway. Could this be correct?
LCDR YAMAUCHI Masaki (51) - 15 November 1940 - 20 August 1942 (YAMAUCHI appointed Navigator of YAMASHIRO this date)
