Cooking is like fashion. Always, I like to try to change. If I'm traveling in a different country - to Australia, the Bahamas, Budapest, Moscow - and I see a new ingredient, I like to try it in a new dish.

I love big shrimp, like Japanese botan shrimp and the meaty ones from Santa Barbara, Calif. In classic Japanese cooking, shrimp like these would be dropped into a broth or boiled as served with sushi. But I think boiling dilutes their great flavor, and they are better when stir-fried.

Sushi is something very exclusive. It is not like a McDonald's, not like a hot dog, not like a French fry. It's very high-class cooking in Japan.

My cooking is very simple, so I don't really use machines at all. A knife, cutting board, frying pan and strainer are my essentials.

My business partner Robert De Niro knows a lot about hotels; he opened the Greenwich Hotel in New York City.

I remember watching steak being cooked on TV and wanting to try it. As a special treat, my mother cooked it for me, and I thought this would be the time I would eat with a knife and fork. Alas, I ate it with chopsticks!
