Junya Kudo is arguably one of the best sushi chefs in Japan. He is obsessed with ingredients, tries to purvey some unusual fish, source locally without being dogmatic in doing so. He displays a technique which resembles movements of a ballet dance rather than those of a chef. His knife skills are stunning and application of his soy sauce a joy to watch.
One example for his drive to source the best was the bonito we got. On very rare occasions a bonito thinks he is a tuna and starts swimming with a group of them. Of course they swim much faster than he normally would do, so they force him to go beyond his natural speed and therefore transform his muscle. There are less than 1% bonitos doing this but it is worth waiting to taste it.
