Help identify japanese pilot Hiroshi Kasai - attack Pearl Harbour

[Adriano Baumgartner]

Hello to all! I am not fond of the Pacific Campaign, so did never read about that. I met here in Brazil the grand-daughter of a japanese pilot who apparently flew on the attack on Pearl Harbour.
His name is HIROSHI KASAI or MYOYA KASAI. This friend of my woman said she did not know if he was a fighter or a bomber pilot. ( I do believe the later ). It seems he survived the war and come to Brazil in mid 50´s. He passed away and I will be looking if she had some photos of his grand-father.
Where could I obtain a list of ALL japanese pilots who took part in the attack of Pearl Harbour? Is there such a list? Does anyone ever heard about this pilot?
Glad to any information on that ( I must say again that I am a ZERO when dealing with Japanese and Marines History, so please excuse any fault ).
Sincerely

Adriano Baumgartner
