What is the perfect sushi?

One of the hardest reservations to get in the world is a seat at Jiro Ono’s sushi counter, a three-Michelin-star restaurant adjoining the entrance to the Ginza metro station, in the basement of a business building in Tokyo. A meal there, which consists of twenty pieces of sushi served one at a time, costs thirty thousand Japanese yen (about three hundred and seventy dollars), and lasts about fifteen or twenty minutes.

In the video below, produced by WocomoCOOK, Jiro and his son, Yoshikazu, talk about their approach to sushi and what they think are the most important factors in creating perfect sushi.
