Hamamoto Miyata, 93, is seen with his roommate, Tokutaro Kojima, at The Hill of Grace Nagasaki A-Bomb Home. &quot;I noticed the big planes in the sky. It was unusual because usually they come from the south but this time they came from the north. I was very busy and continued working, not paying too much attention, and then I saw a flash of blinding light and heard the sound of the explosion.&quot;
