Why And How Was Yokohama Destroyed In The War?

I think the thing that makes Yokohama special is the fact that it has so many cultural aspects all rolled into one. I have not seen any other place in Japan that does this and I feel that it makes foreigners feel more welcome. In this place they show respect to locals and foreigners alike. Evidence of this is shown because of things like the signs having multi language subtitles, Restaurant diversity and more. I feel that this is the perfect place for foreigners in Japan.
