Hi jamerican: I agree about the oysters, they were terrific. My best friend is from and lives in Hiroshima (she and I went to college in the States at the same time)so my wife and I had the grand tour, of course including Miyajima.
But I've also lived in Taiwan and Shanghai, and especially in China there is still an oft expressed hatred of Japan for what happened during that war. So having heard from that side, I'd say it goes beyond "interpretation" into "a gross misrepresentation of history". I can't tell you how many Chinese have told me stories about the death or rape of family members. When it hits your family, you don't forget so easily. They can't understand why Japan doesn't address its wartime behavior as Germany did.
If you're going to build a show around the theme of cities that have suffered from nuclear attack, there's no way you can avoid that issue and consider yourself objective in any way, especially when Anthony Bourdain is involved.
The actual number of estimated casualties for the invasion of Japan from the US side was 1 million US and 5 million casualties. Not sure where you came up with 250 million. The US population didn't reach 200 million until well into the '60s.
The other factor Japan doesn't mention is that if the US had invaded from the south, Russia would have invaded from the north and Japan would have become another Germany, divided with the likelihood of Tokyo also being divided. I think most Japanese are glad that didn't happen.
When I'm in Tokyo, I feel like I'm in just another big international city. But when I'm in Hiroshima, I feel like I'm in Japan. I like Japan much better.
