Each of those dishes are Chinese as well. The Chinese weren’t really happy with the Japanese in WWII either. My daughter eats Teriaki Chicken at our local take out. Tofu and edamame are standard Oriental foods. Watch Kimchi Chronicles or Simply Ming on PBS. Those foods are not simply Japanese.
If they had served Sushi and Yakisoba it would have been Japanese.
That being said, bad PR move. Most people don’t know the difference in Oriental food.
Imagine if they'd been serving dorayaki ~ now that'd been something (d'oro = gold piece, and yaki = cooked in skillet on stove or fried ~ not baked) ~ a regular transcultural phenom of ancient etiology.
Rice ~ that'd be the ticket ~ if they'd had Kokuho Rose from Koda Farms ~ flop some fresh minnows on top ~ pour on some sriracha sauce, you'd get something real close to what the hardier Marines at Camp Pendleton eat when they get cut loose to check out Vista.
Teriyaki is just chicken roasted/broiled/boiled/baked part way and finished up with a soyu/brown sugar concoction ~ some dissolved ginger, and maybe a hot spice or two ~ you take that and braise it on a grill for a few minutes until it flames.
Now that's some eats. I don't think the Japanese invented the chicken or soyu or brown sugar though.
Something almost peculiar to the Japanese when it comes to food is the very round little fish that are dried and tossed into the package with the rice senbei (crackers) ~ Otherwise that's all pretty common Asian fare, but the Japanese mix that fish in like a crackerjack prize!
Believe me, all of Japan's Asian victims have long memories. There is far more lingering resentment over Japan's WWII actions in Asia than in the USA.
As I heard right from from the mouth a Japanese Historian, Professor and 'scholar' on the History channel: "Japan has never invented anything." And he was proud of this and Japan's history of 'borrowing' things from other countries.
Their language and writing was 'borrowed' from the Chinese. Ditto for their swords and way of fighting with them - originally from China. And their hand to hand fighting was 'borrowed' from Korea. This Japanese expert then clarified that after they 'borrow' all these things, they just, "improve on them".
And this 'borrowing' and 'improving' things from Japan is still evident today. All electronics in our houses were invented here, or with luxury cars - Germany, and Japan just 'improved them'.
So I'm surprised that Japan 'invented' Sushi. Their history shows otherwise.
Thank you for a reasonable statement
