SHIZUO TSUJI was the president of the Ecole Technique Hoteliere Tsuji, the largest culinary school in Japan. He published extensively, writing the best- selling classic Japanese Cooking: A Simple Art and more than thirty books on gastonomy, music and travel in Japanese. Recognized by the French government for his tireless work in promoting French cuisine and culture in Japan, he was named Meilleur Ouvrier de France (M.O.F.). Mr. Tsuji passed away in 1993. KOICHIRO HATA, head of the Japanese cookery facilities at Ecole Technique Hoteliere Tsuji, appears regularly on nationally broadcast television programs, and is the coauthor of numerous cooking books in Japanese. He teaches and lectures on Japanese food not only in his native land, but abroad as well, most notably in the United States and Thailand. A discerning diner by profession, the low-profile head chef is invariably recognized by former students whenever he visits any of Japan's finer restaurants.
