How do japanese, chinese, korean, vietnamese, thailand foods differ?

they are all classified as asian food, but whats the difference? What nation originated sushi and sashimi?

I want to start a asian restaurant in baltimore but with a local twist, making dishes made with indigenous seafood like oysters, rockfish, blue crabs, and perch.How do japanese, chinese, korean, vietnamese, thailand foods differ?
You are asking a VERY broad question here. Each country is vastly different and influenced by different regional cultures, ingredients, and tastes so it's hard to generalize what is dfferent about each. Are you asking about food, spices, cooking styles? They're all very different!

- Sushi and Sashimi ... originated in Japan



Here are some broad generalizations of each I can think of:

Japanese - a lot of it is rice: sushi, sashimi, nigiri, rice wine, rice vinegar. A lot of seafood - fish, shrimp, eel, seaweed. Noodles: udon



Chinese - this country is huge and the northern cuisine is more spicier than the southern. Dim Sum is a southern specialty. Kinda like tapas. Lots of stir frys. Rice is a staple. BBQ meats: pork, duck, chicken. Steamed dishes: fish, etc. Lots of different types of foods!



Korean - bulgogi, chigaes, kim chi, etc. lots of stews, beef, pickled cabbage, side dishes, bean sprouts, sesame oil, pototoes. Kim bap, similar to maki rolls.



vietnamese - pho - beef noodle soup, broken rice with vietnamese pork or sausages, fresh ingredients: bean sprouts, cilantro, basil



thailand - spicy, green and red curries, lots of basil, bean sprouts, (pretty similar to vietnamese food) but lots more curries and stir frys



I may be wrong. But that is my sweeping generalizations based on all those types of foods I've tried.



If you are planning on opening an asian restaurant, I strongly suggest doing some research elsewhere --- go to your local bookstore and find an Asian cookbook to actually see what the differences you are trying to find, try the different ethnic restaurants. You'll get more out of that then asking a question on here.How do japanese, chinese, korean, vietnamese, thailand foods differ?
China is big.their food varies in provinces

i think koreans are good at barbeque

japanese cuisine has good seafood like eel ,but they really eat seaweed(or sth looks similar) a lot

thai food is spicy and sweet

not clear about Vietnamese,but i think it is close to Chinese cuisine

Good luck!
