Is the rendering of the name in that post correct? The source has been removed. Was it "西沢義子", or are they different characters that look rather similar? There's also a "Nishizawa Yoshiko" on post #412194 , but the second kanji in that name is different (澤). From what I can gather from a wiki, based on Nishizawa Hiroyoshi, Japan's "ace of aces" in the war. Who also seems to have different kanji associated with his name, depending on source...
