The ambush of Yamamoto’s aircraft was, according to what I have read, was attributable to SIGINT, which had recovered his itinerary. U S Army Air Corps assets knew where and when he would be and they were there to take him out of the game. I got to the Philippines in 1961 and there was still a lot if ill will toward Jap. Then I got assigned to Japan in 1965 and I must say that they’d done a magnificent job of rebuilding in the two decades since the surrender.
I was in Dutch Harbor (Unalaska) Alaska in 1969 when a disabled Japanese fishing vessel put into port. There was Damn near a riot by some of the old locals, they were still smarting from getting bombed and damage done by the Japanese in WW2.
