Is sushi in the US the same as in Japan?

A lot has been "americanized":

Article about the sushi war in US

Japanese restaurants in America, Japan has neither jurisdiction, or a stake in dictating how American sushi is prepared.

If within Japan there are many variations of certain foods, why could not be a variation of sushi, specially when is served outside Japan. Avocado roll was invented in California, yet they now serve it in Japan.

Kim said the Japanese do not have much right to claim sushi as a product of their food culture. 'Sushi and sashimi are originally from China and Korea," he insists. "The Japanese have only started eating sushi since World War II. Koreans and Chinese have been making sushi and sashimi for thousands of years."

Well to tell the truth I was not a fan of sushi. Had tried it many different places from NY all the way to Long Beach Ca.. Until we went to Japan for 6 mths. I avoided it at all cost. But one day a friend of ours came over and she made sushi. It is very rude and offense if you don´t try it. And as she was my husbands boss wife, lets just say he would have killed me if I didn´t try it!! Surprizingly I loved it so much I was a little pig about it. From that moment on where ever we went I was served sushi. Made from shrimp all the way to blowfish. But once we came back to the states, it´s just doesn´t taste the same. But compared to the cost of flying over to Japan. The americanize version is good.

Real Japanese sushi should be uniform in taste and appearance anywhere you eat it. And yes, the ingredients will be fresher in Japan.

for the most part it is the same, except for maki sushi, which you would be hard pressed to find in japan (i.e. california rolls).......

in japan you will find alot more of temaki, often served with daikon and pickled ginger.

If you mean ingredient wise, I will say yes>>>>>>>....

probably alot fresher there and shocked probably
