I always have dashi in my refrigerator—it's the almighty Japanese ingredient.

When I'm on the road, I wake up early and walk a lot. I'm very healthy. But when I come back home, I am more tempted by guilty pleasures, such as eating too many sweets and sleeping a lot.

Cook more often. Don't study; just cook.

New York is my, you know, second hometown.

Because I'm a chef, I eat out frequently, so it's hard for me to control what I consume in terms of calories. But when I'm at home, I eat what my wife cooks for me. She works hard to avoid making foods that are high in calories and cholesterol, so most of the time, she makes vegetarian dishes.

I've been making sushi for 38 years, and I'm still learning. You have to consider the size and color of the ingredients, how much salt and vinegar to use and how the seasons affect the fattiness of the fish.

Japanese chefs believe our soul goes into our knives once we start using them. You wouldn't put your soul in a dishwasher!
