On this day of infamy in 1941 the popular restaurant chain Kimmel's was confronted with a surprise challenge to its dominance of the West Coast seafood dining scene when its archrival, the Tokyo-based Yamamoto franchise, opened its first U.S. branch in Honolulu.

"It was like somebody dive-bombed us". Kimmel's vice-president Chester Nimitz said of the effect the Honolulu Yamamoto's opening had on Kimmel's corporate profits; within six months sales had dropped 50% from the previous year and the company was faced with the prospect of having to close a third of its branches on the West Coast.
