Oh, I've been dreaming of Jiro style grilled omelet since I viewed the documentary, Jiro Dreams of Sushi, many months ago. I looked for copy cat recipes online but didn't find any that looks like Jiro's but read that his recipe has mountain yam, shrimp called shiva ebi, sugar, salt, mirin, and a little soy sauce. In the movie an apprentice does preparation techniques for 10 years before he is allowed to try making tamagoyaki.
