[ijnfleetadmiral]

I have an officer named FUMIZAWA Yoshimizu as being appointed Commanding Officer of netlayer NISSHO MARU NO. 3 on 30 March 1946. Was he a former Reserve Officer or an Eta Jima Graduate? I have an officer named FUMIZAWA YOSHINAGA 文沢義永 from Eta Jima Class 68, so I'm wondering if this is the same person and just a mis-translation of the name. TIA for any help on this.
