Correction: What do you think of Japanese food?
(The question needs to begin with a capital. 'Japanese' as it is a proper noun, a populace and a language - this also needs a capital letter at the beginning).
I adore Japanese food. It is not only about sushi as there are many different types of other Japanese cuisine such as Ramen, Sashimi, Yakitori, Tempura, Wasabi and the noodles(Udon....). Everything has a delicious flavour. Vegetables are freshly cooked. Spices compliment the dishes. Also the various Japanese teas are a fantastic accompaniment to any meal.
