F100- gentleman above provide to you useful info for finding this pilot. As well you are live in Brazil, I would like to suggest you to try to contact Sidnei Maneta, his is illustrator and work with some proven researchers in the field of the Japanese aviation history. On this board is also active David Aiken and I hope that he would also spot your interest and be able to help you.
One note- term Jap or Japs is used regularly during the WW2 but today this is offending term, something like term n****r for black people. I am sure that you did not have informed about this so please if possible, do not use this term in future.
Cheers
