The movie is delightful, with great images of sushi and every stage of sushi making, from the shopping at the Tsukiji fish market, to the preparation of perfect rice, to the cutting (and sometimes cooking) of the fish and assembly of the finished bite. The subtext of the movie is how passionate Jiro is about his work, and just how hard it is to be a great sushi chef. Early in the movie, Jiro sums it all up, with appropriate Japanese modesty and understatement:
Once you decide on your occupation, you must immerse yourself in your work. You have to fall in love with your work. Never complain about your job. You must dedicate your life to mastering your skill. That's the secret of success and is the key to being regarded honorably.Only in Japan.
